PredecessorCP System II

The CP System III (CPシステムIII, CP shisutemu 3), also known as Capcom Play System 3 or CPS-3 for short, is an arcade system board that was the successor to Capcom's CP System and CP System II arcade hardware. It was first used in 1996 with the arcade game Red Earth. It would be the last proprietary system board Capcom would produce before moving on to the Dreamcast-based Naomi platform. The arcade system saw new releases up until mid 1999. Technical support for the CPS-3 ended on February 28, 2019.[2]

Like its forerunners, games can be exchanged without altering the core hardware. The CP System III uses CDs instead of separate daughterboards to store the games on, which are then loaded onto the system's CD drive to be stored into memory to allow for it to be played. Like its predecessor, games are encrypted, and must be decrypted via game-specific security cartridges, which will decrypt the contents stored within the system memory in run time.

History

[edit]

The CP System III became the final arcade system board to be designed by Capcom. It features a security mechanism; games are supplied on a CD, which contains the encrypted game contents, and a security cartridge containing the game BIOS and the SH-2 CPU[3] with integrated decryption logic, with the per-game key stored in battery-backed SRAM. Capcom chose the CD medium in order to keep down the price of the system.[4]

In a change from its predecessors, the CP System III consists of a single board instead of two separate boards. The board contains components common to all CP System III games, and includes a slot for the security cartridge. The games themselves are stored on a CD instead of on a separate board, which is then readable by the provided SCSI CD-ROM drive that is connected to the main board. The CP System III has extensive sprite scaling capabilities that all games for the system used. It does not contain the QSound sound chip used on its predecessor, the CP System II, and in its place is a custom 16-channel stereo sound chip. One of the unique features of the CP System III is widescreen support for certain games; only one game has officially made use of this feature, which is Street Fighter III: 2nd Impact.

When the CP System III board is first powered on, the contents of the CD are loaded into a bank of Flash ROM SIMMs on the motherboard, where it is executed. The program code is then decrypted at run time via the security cartridge. The security cartridge is sensitive to any sort of tampering, which will result in the decryption key being erased and the cartridge being rendered useless. Games become unplayable when the security cartridge has been tampered with or when the battery inside the security cartridge dies. The lone exception is Street Fighter III: 2nd Impact, which uses a default set of decryption keys that are written to dead cartridges on boot,[3] making it the few, if not the only CPS-3 games prevalent after support was dropped, due to its immunity to cartridge tampering or suicide.

In June 2007, the encryption method was reverse-engineered by Andreas Naive,[5] making emulation possible.[3] Later developments led to the eventual bypassing of the suicide and security routines of the games as well as a development of a so-called "super cartridge" capable of running all CPS-3 games.[6]

Capcom ceased manufacturing the CP System III hardware after 1999. Capcom ended most of the technical support for the hardware and its games on March 31, 2015.[7] Battery replacements ended on February 28, 2019,[2] ending all official support of the CP System III hardware and software.

from Grokipedia
The CP System III (CPS-3), also known as Capcom Play System 3, is an arcade system board developed and released by in 1996 as the direct successor to the (CPS-2), marking the company's final proprietary 2D-focused arcade hardware platform. It employed a hybrid storage system paired with security key cartridges (dongles) to authenticate and load games, enabling enhanced 2D , fluid animations, and high-fidelity through its custom , while incorporating anti-piracy measures to protect arcade operators. The board supported JAMMA+ compatibility for standard arcade cabinets, accommodating two-player simultaneous gameplay with 8-way joysticks and up to six buttons per player, and was powered by a SH-2 32-bit RISC CPU clocked at 25 MHz, alongside via modules for game data storage and a drive. Despite its technical advancements, the CPS-3 had a brief production run, with only six official games released between 1996 and 1999, primarily fighting titles that showcased its capabilities in sprite-based visuals and Q-Sound audio. These included Red Earth (known as Warzard in Japan, 1996), the Street Fighter III trilogy—New Generation (1997), 2nd Impact: Giant Attack (1998), and 3rd Strike: Fight for the Future (1999)—as well as JoJo's Venture (1998) and JoJo's Bizarre Adventure (1999). The system's high manufacturing costs, complex security implementation, and vulnerability to piracy contributed to its limited adoption, leading Capcom to abandon further development by 1999 in favor of third-party platforms like Sega's NAOMI for subsequent arcade titles amid the industry's shift toward 3D graphics. The CPS-3's legacy endures through its influence on competitive fighting game culture, particularly via Street Fighter III: 3rd Strike, which remains a staple in and emulation communities due to its innovative mechanics and character depth, though original hardware is now rare and sought after by collectors.

Overview

Background and Purpose

The Play System III (CPS3) was 's third-generation proprietary arcade hardware platform, released in 1996 as the direct successor to the CPS2 system introduced three years earlier. This platform marked a pivotal shift for from ROM-based boards to a SCSI architecture, which allowed for vastly expanded data storage to accommodate more intricate game designs without the prohibitive costs of large ROM chips. Developed amid escalating issues that had undermined CPS1 and CPS2—where bootleggers reverse-engineered hardware to produce cheap unauthorized duplicates—CPS3's core purpose was to safeguard Capcom's through robust hardware encryption and secure CD loading protocols. These measures deterred illicit copying, which had previously led to widespread revenue losses and glitch-ridden fakes in arcades worldwide, while enabling the creation of advanced 2D fighters and RPGs with richer content. In the mid-1990s arcade landscape, where operators sought enhancements like audio and video to compete with emerging home consoles, CPS3 addressed rising development budgets for ambitious titles such as by leveraging cheaper optical media amid falling ROM production expenses. The system debuted in late 1996 with Warzard (released internationally as Red Earth), Capcom's fantasy-themed that showcased the platform's capabilities in a transitioning market.

Key Innovations

The CP System III (CPS-3) introduced integration via a interface, enabling storage of high-fidelity graphics, detailed animations, and CD-quality audio on discs with capacities up to 650 MB, a substantial increase over the CPS-2's ROM limits of approximately 40 MB. This shift allowed developers to incorporate larger asset libraries, supporting richer visual and without the physical constraints of cartridge-based systems. A major advancement in security was the hardware security , known as the key chip or security cartridge, which contained a dedicated SH-2 CPU and SRAM to store unique decryption keys for each game. Paired with encrypted CD data protected by algorithms, this mechanism was the first in Capcom's systems to employ per-game unique keys, effectively preventing unauthorized copying and bootleg reproductions by requiring the physical cartridge for data decryption during loading. The system enhanced 2D graphics processing with support for advanced sprite effects, including scaling, , and transparency, which facilitated more dynamic and fluid animations compared to prior hardware. These capabilities were particularly evident in fighting games like , where they enabled smooth character movements and visual effects such as variable-sized sprites and blended overlays. Additionally, CPS-3 utilized Flash RAM modules via seven SIMM slots—with variable capacities per game (commonly 16 MiB modules, but up to 128 MiB for some slots in later titles such as Street Fighter III: 3rd Strike)—for non-volatile storage of operator settings and high scores, eliminating the need for battery-backed CMOS memory used in earlier systems like CPS-2 and improving long-term reliability in arcade environments.

Development History

Design Origins

The CP System III (CPS3) represented a direct evolution from Capcom's earlier (CPS2), maintaining the modular board architecture that allowed for flexible game daughterboards while introducing substantial enhancements to address limitations in performance and security. This design philosophy built upon the CPS2's success in powering blockbuster titles, but shifted to a more advanced SH-2 32-bit RISC processor running at 25 MHz to deliver superior computational power for complex tasks, including real-time graphics rendering and data processing essential for next-generation arcade experiences. The transition to storage via interface further marked a departure from ROM-based systems, enabling larger game assets while aligning with the emerging market shift toward optical media in arcades during the mid-1990s. Development of the CPS3 was spearheaded by 's in-house hardware engineering team, motivated by the monumental commercial triumph of on the CPS1 and CPS2 platforms, which had generated billions in revenue and established as a leader in fighting games. The system's conceptualization emphasized longevity and resilience against the rising threat of home console ports, such as Sony's PlayStation, by prioritizing hardware capabilities that exceeded contemporary consumer systems in 2D sprite handling and fluidity. A primary design challenge stemmed from rampant bootlegging of CPS2 games, particularly variants, which proliferated unauthorized copies and eroded Capcom's arcade revenue streams. To counter this, the CPS3 incorporated robust mechanisms from the outset, with game data stored on encrypted CDs that required on-board decryption, elevating production costs but ensuring greater protection against replication compared to prior systems. This focus on security over affordability resulted in a premium hardware price point, reflecting Capcom's commitment to safeguarding in an era of widespread arcade piracy. During the prototyping phase in the mid-1990s, conducted initial evaluations of integration to confirm viable data loading speeds compatible with seamless, real-time gameplay, laying the groundwork for the system's 1996 debut with Red Earth (Warzard).

Production Timeline

Mass production of the CP System III hardware began in mid-1996 at 's facilities in , marking the company's transition to a new arcade platform amid the evolving demands of the late-1990s gaming industry. The system's design emphasized advanced features and -based game loading, but its high manufacturing costs—driven by custom encryption hardware and battery-backed mechanisms—resulted in a limited production run, with estimates suggesting only a small fraction of the volumes seen in prior systems like the CPS-2. This constrained output contributed to the platform's short operational lifespan, as prioritized cost efficiency in an arcade market increasingly challenged by home consoles. The initial release occurred in Japan in late 1996, debuting with the title Warzard (internationally known as Red Earth), which showcased the system's capabilities in a hybrid fighting-RPG format. This launch was followed by a measured international rollout in 1997, introducing Red Earth and Street Fighter III: New Generation to markets outside Japan, allowing Capcom to test global reception while managing distribution logistics. Over the next two years, additional titles like Street Fighter III: 2nd Impact and JoJo's Bizarre Adventure expanded the library, but the platform's rollout remained focused primarily on established arcade regions to mitigate logistical challenges. By 1999, following the release of on May 12 and the final CPS-3 game in September, discontinued production of the hardware, pivoting toward more affordable alternatives such as Sega's Naomi arcade system and direct console ports to capitalize on the growing home gaming sector. The decision was influenced by the CPS-3's escalating operational expenses and vulnerability to , which deterred widespread adoption. Regional variations included adaptations for the U.S. market, where JAMMA harness modifications addressed voltage compatibility issues common in North American arcade cabinets operating at 110-120V, unlike Japan's 100V standard. Exports to and other parts of were notably restricted, primarily due to heightened risks that the system's robust anti- measures were designed to counter but could not fully prevent in unregulated markets.

Technical Specifications

Core Hardware Components

The CP System III (CPS3) utilizes a SH-2 32-bit RISC processor clocked at 25 MHz as its main CPU, which is embedded within the security cartridge and manages essential tasks such as game logic processing, data decryption, and AI computations. The system's memory architecture includes dedicated RAM for operations such as 256 KB color RAM and 32 KB system support (SS) RAM, while game storage is handled by variable-capacity configured using modules (e.g., combinations of 32 Mbit, 64 Mbit, and 128 Mbit modules, totaling up to 768 MB or more depending on the game, such as 2×64 Mbit + 5×128 Mbit for Street Fighter III: 3rd Strike). These store game data loaded from , with in the security cartridge. Storage is provided by a CD-ROM drive ( CR-504) operating at 4x speed, which loads game data from discs into the flash SIMMs, complemented by a security key chip in the form of a cartridge that stores encryption keys to protect and game assets. Input/output interfaces feature a standard JAMMA connector for integrating with controls and power supplies, RGB analog video output supporting a of 384x224 pixels, and stereo audio output through a custom (DAC) for immersive sound delivery.

Graphics and Audio Systems

The graphics subsystem of the CP System III utilizes a custom rendering engine capable of displaying up to 32,768 colors (15-bit RGB) on screen, with individual objects supporting 256 colors each. This setup enables vibrant 2D visuals suitable for arcade fighters, where up to 1,024 sprites can be rendered simultaneously, incorporating hardware scaling for dynamic resizing effects. The tilemap system includes four independent scrolling layers plus one text overlay layer, allowing for complex background and multi-plane environments typical in Capcom's titles. Complementing the visuals, the audio system features a custom 16-channel, 8-bit sample playback chip derived from Q-Sound technology, which supports positional audio processing to create immersive 3D soundscapes. This configuration delivers high-fidelity effects and voice work, enhancing spatial awareness in scenarios like fighter clashes, with amplified output for cabinet speakers. The chip's design emphasizes realistic audio rendering, drawing on Q-Sound's legacy for surround-like effects without additional hardware. Video output is handled at a of 384×224 pixels in standard mode (or 496×224 in ), running at 60 Hz to ensure smooth 60 frames per second playback. This configuration integrates with JAMMA+ connectors for direct monitor compatibility, supporting RGB signals that maintain sharp without interlacing artifacts. The CPU-driven rendering coordinates with these subsystems for efficient DMA-based decompression, optimizing performance for real-time arcade demands.

Security and Software Features

Anti-Piracy Mechanisms

The CP System III (CPS3) incorporated advanced cryptographic protections to safeguard game content from unauthorized replication and distribution. Central to this was an encryption scheme where each game's contained encrypted data protected by unique keys stored exclusively in the accompanying security cartridge. During the loading process, the cartridge's SH-2 CPU performed decryption of the data. The security cartridge housed critical components, including a battery-backed custom ASIC with the decryption keys and logic for secure verification, rendering the hardware inoperable without it. The battery prevented key loss, and detection of tampering—such as voltage variations, , or improper removal—triggered a suicide mechanism that permanently erased the keys. In the boot process, CPS3 loaded the cartridge, which used its CPU to verify the CD-ROM's legitimacy and . Failure or tampering resulted in permanent key erasure, locking out the cartridge and requiring servicing for revival. These mechanisms proved highly effective in deterring widespread bootlegging of CPS3 titles, maintaining Capcom's control over distribution until hardware hacks and recovery methods emerged in the mid-2000s. However, the system's reliance on proprietary cartridges increased operational costs for arcade operators, often necessitating Capcom servicing to replace or reprogram components after battery failure or suspected tampering.

Game Loading Process

The game loading process on the CP System III (CPS3) commences with the operator inserting the game-specific security cartridge—containing the , decryption keys, and authentication data—into the dedicated slot and placing the corresponding into the drive. Upon powering on the system, a (POST) verifies the integrity of the hardware components, including the flash SIMMs and the security cartridge, before loading the kernel from the cartridge into system RAM to initialize the SH-2 CPU and core peripherals. The controller subsequently accesses the to read the encrypted game sectors, which the cartridge's CPU decrypts using the provided keys and algorithms. This data, encompassing , audio, and program assets, is then decompressed and copied to the onboard flash SIMMs for storage. For the initial installation of a new game, this transfer process requires 25 to 45 minutes, as the SIMMs must be fully populated according to the game's memory requirements (e.g., up to 128 MB for larger titles like Street Fighter III: 3rd Strike). Subsequent boots bypass the full CD transfer by loading the pre-installed assets directly from the flash SIMMs into VRAM and SRAM, enabling a rapid initialization typically lasting under a minute. During runtime, the system facilitates dynamic asset streaming from the SIMMs to support level transitions and progression without full reloads. Operators access a service menu during the boot sequence by pressing the dedicated service button, allowing configuration of DIP switches for parameters such as game difficulty, credit allocation, and cabinet settings. Error handling includes halting the process and displaying numeric error codes (e.g., ERROR XX indicating SIMM slot failures) if verification or decryption issues arise; severe security breaches, such as cartridge battery depletion or tampering detection, trigger a suicide mechanism that erases the decryption keys, rendering the cartridge inoperable and requiring replacement. Original CPS3 hardware does not support CD hot-swapping for multi-game operation, necessitating a full cartridge and exchange for title changes.

Games and Software Library

Released Titles

The CP System III supported only six official games, all released between 1996 and 1999, with primary distribution in Japan and the United States and no major European variants. This limited library stemmed from the system's high development costs, driven by its advanced hardware requirements and robust security measures, combined with the platform's short lifespan as the arcade industry transitioned toward 3D technologies. The inaugural title, Warzard (released in Japan on October 23, 1996, and internationally as Red Earth in 1997), is a hybridizing RPG elements, where players select from four characters to battle sequential fantasy bosses in a quest-driven . Street Fighter III: New Generation, launched in 1997, introduced a fresh 2D installment with 16 initial characters and pioneering mechanics like the parry system. Its update, Street Fighter III: 2nd Impact - Giant Attack (also 1997), expanded the experience by incorporating Super Arts, additional stages, and two new fighters, Hugo and Urien. JoJo's Venture (1998), the first game in the series on CPS-3, is a 2D fighting game featuring characters from Hirohiko Araki's with stand-based combat mechanics. The trilogy's finale, : 3rd Strike - Fight for the Future (1999), shifted to a 3-on-3 structure with polished mechanics and a complete roster of 16 fighters. JoJo's Bizarre Adventure: Heritage for the Future (1999), an updated version of JoJo's Venture, expanded the roster and refined stand-based combat mechanics with additional characters and stages drawn from the .

Technical Adaptations in Games

The Street Fighter III series exploited the CPS3's sprite processing hardware to enable rotation effects, facilitating dynamic camera angles that simulated 3D-like movement in 2D fights. This adaptation contributed to the series' renowned fluid animations and system, showcasing the board's 1024-object limit with hardware scaling. The games also integrated Q-Sound audio for voice-acted taunts, delivering immersive, directional sound cues that enhanced character personality without compromising performance. In Street Fighter III: 3rd Strike specifically, developers optimized streaming to preload assets for super moves, ensuring seamless transitions during high-intensity sequences like Super Art activations. Red Earth (known as Warzard in ) utilized the CPS3's capabilities to load detailed animated backgrounds, blending static sprites with environmental elements for a more cinematic RPG-fighting hybrid experience. The game employed a password system for continuing character progression, allowing players to resume leveling and equipment upgrades across arcade sessions—a novel feature for the era. Large boss sprites, reaching up to 4MB uncompressed, were decompressed dynamically from CD storage during runtime, balancing the hardware's 16MB RAM constraints with detailed, multi-layered visuals. JoJo's Bizarre Adventure pushed the CPS3's graphics pipeline with alpha blending for ethereal stand effects, creating translucent overlays that amplified the supernatural combat mechanics drawn from the . The title also implemented 3D positional audio, utilizing the Q-Sound derivative's 16-channel capabilities to simulate arena echoes and spatial sound for ability activations, maximizing the system's potential. Across all CPS3 titles, developers applied custom asset compression algorithms to adhere to load times between rounds or levels, mitigating the CD-ROM's seek latency while fitting expansive sets into available RAM. The system's per-game keys precluded multi-board linking configurations common in prior CPS hardware, as the added overhead would have exceeded processing limits and increased risks.

Legacy and Modern Relevance

Industry Impact

The CP System III (CPS3) represented Capcom's final foray into proprietary arcade hardware, but its development and deployment costs—significantly higher than subsequent third-party alternatives—prompted a strategic pivot away from custom systems. Priced as a premium board compared to Sega's NAOMI, the CPS3's complexity, including reliance on CD-ROMs for game data and battery-dependent security cartridges, escalated production expenses and maintenance challenges for operators. By 1999, Capcom shifted to more cost-effective platforms like the Sega NAOMI (a derivative) and Sony ZN-2, enabling broader game distribution without the burdens of bespoke engineering; this transition marked the end of Capcom's in-house arcade board era, allowing focus on software for multi-platform releases. In the genre, the CPS3's flagship titles, particularly the series, established enduring technical benchmarks that elevated competitive play and inspired subsequent designs. Innovations such as the mechanic—allowing precise timing-based deflection of attacks—and refined input buffering systems enabled fluid, high-skill combos and defensive options, shifting emphasis toward execution depth and strategic layering over simpler patterns in earlier fighters. These elements, combined with the series' emphasis on accessible yet analyzable frame data, influenced genre evolution by promoting detailed community breakdowns of move timings and interactions, a practice that became standard in tournaments. Developers like of cited Street Fighter III as a personal favorite. The CPS3's market footprint was brief, spanning releases from 1996 (Warzard) to 1999 (Street Fighter III: 3rd Strike), a period when arcades faced existential pressure from advancing home consoles like the PlayStation and . This shortened lifecycle amplified the system's exclusivity, as operators hesitated to invest amid declining coin-op revenues and the allure of domestic ports—Street Fighter III: New Generation arrived on in 1999, accelerating the migration of arcade experiences to living rooms. While the CPS3's robust anti-piracy measures, including encrypted CDs and real-time authentication via security carts, curbed bootlegging more effectively than the CPS2's battery-vulnerable encryption (which inadvertently prolonged CPS2's dominance through widespread cracking and board revivals), they also introduced trade-offs like fragility and limited game support, deterring broader adoption in a contracting arcade sector.

Emulation and Preservation Efforts

Emulation of the CP System III (CPS3) has been hindered by its sophisticated mechanisms, which were implemented to deter and unauthorized replication of game data. Initial support in the Multiple Arcade Machine Emulator (MAME) was achieved in June 2007 through efforts by developers including Andreas Naive, Tomasz Slanina, ElSemi, and Philip Bennett, enabling basic functionality for titles like Street Fighter III: 3rd Strike. Subsequent updates refined the emulation, addressing issues such as video timing and no-CD configurations, with notable improvements in MAME 0.139 (2010) that separated ROM data into individual flash components for more accurate loading. These advancements relied on dumped and analyzed security elements from original hardware, allowing cycle-accurate playback without physical dongles in later versions. Official ports to consumer platforms have contributed to the preservation of CPS3 games by making them accessible beyond aging arcade hardware. The Street Fighter Anniversary Collection, released in 2004 for and , included a port of : 3rd Strike with enhancements like high-resolution modes. In 2018, : 3rd Strike was re-released as part of the Street Fighter 30th Anniversary Collection for , , , and PC, featuring online multiplayer and updated . Red Earth, previously unavailable outside , was ported in the launched on June 24, 2022, for modern consoles and PC, including rollback for competitive play. Preservation of original CPS3 hardware faces challenges from component degradation, including failing CD-ROM drives that load game data and security dongles prone to battery failure, which can erase decryption keys and "suicide" the cartridge. Community initiatives, such as those on Arcade-Projects forums, offer repair guides, including SCSI emulators like BlueSCSI to replace optical drives with SD card-based alternatives, and archives of verified ROM sets for emulation. Modern hardware recreations via field-programmable gate arrays (FPGAs) aim to replicate CPS3 functionality without relying on scarce original parts. project features an ongoing CPS3 core developed by Jotego, with schematic tracing completed by January 2023 after 3.5 months of full-time effort; the core remains in development as of 2025.
