The {{Nihongo|'''CP System III'''|CPシステムIII|shīpī shisutemu surī}} or '''CPS-3''' is an [[arcade system board]] that was first used by [[Capcom]] in 1997 with the arcade game ''[[Red Earth (video game)|Red Earth]]''. It was the second successor to the [[CP System]] arcade hardware, following the [[CP System II]]. ==History== The CP System III is the latest arcade system board 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 [[SuperH|SH-2]] CPU<ref name="mamedriver">[http://www.mamedev.org/source/src/mame/drivers/cps3.c.html MAME's CPS-3 driver]</ref> with integrated decryption logic, with the per-game key stored in battery-backed [[SRAM]]. When the CP System III board is first powered on, the contents of the CD are flashed onto a bank of [[SIMM]]s 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 became unplayable when the battery inside the security cartridge died, which had to be replaced at cost to the owner. Furthermore, the CP System III was only capable of 2D graphics at a time when most games were being developed with [[3D graphics card|3D]] hardware in mind. In June 2007, the encryption method was reverse-engineered by [http://andreasnaive.blogspot.com/ Andreas Naive], making [[Video game console emulator|emulation]] possible. The encryption turned out to be a fairly straightforward combination of rotates and XORs.<ref name="mamedriver"/> ==Specifications== * Main [[CPU]]: [[Hitachi, Ltd.|Hitachi]] HD6417099 ([[SuperH|SH-2]]) at 25 MHz * Storage: ** [[SCSI]] [[CD-ROM drive]] ** [[RAM]] (variable amount) ** [[Flash ROM]]: 8 x 16 [[MiB]] * Sound chip: 16-channel 8-bit sample player, stereo * Maximum number of colors: 32768 (15 bit colour, 555 RGB) ** Palette size: 131072 pens ** Colors per tile (backgrounds / sprites): 64 (6 bits per pixel) or 256 (8 bits per pixel), selectable ** Colors per tile (text overlay): 16 (4 bits per pixel) * Maximum number of objects: 1024, with hardware scaling * Scroll faces: 4 regular + 1 text overlay 'score screen' layer * Scroll features: Horizontal & vertical scrolling, linescroll, linezoom * Framebuffer zooming * Color blending effects * Hardware RLE decompression of 6 bpp and 8 bpp graphics through DMA * Resolution, pixels: 384×224 (standard mode) / 496×224 (widescreen mode) * Known games on this hardware: 6 ==List of games== <!-- To edit the text of this article, skip past the table. --><!-- Dates given are the earliest possible dates shown in the game's bootup screen, any region. --> {| class="wikitable sortable" style="width:100%" !
