Capcom Play System 3 (CPS3)
Capcom Play System 3 (official abbreviation CPS-3) & mdash; arcade system developed and presented by Capcom in 1996 along with Warzard (known outside Japan as Red Earth).
CPS-3 was the last arcade system developed by Capcom. The system used the following copyright protection mechanism: games were delivered on CD with encrypted game content, and a special cartridge containing the game BIOS and an SH-2 central processor with an integrated logical decryption system and a game key stored in the SRAM memory card. When the machine is first started, the contents of the CD are transferred to the SIMM memory on the motherboard, where the contents are played. The security cartridge is very sensitive to any tampering, since the decryption key could be erased, and, accordingly, the cartridge became useless.
Games became unplayable when the battery located in the security cartridge stopped working, and therefore needed to be changed for further operation. Also, the CPS-3 could only support more complex 2D graphics, which was both an advantage and a disadvantage of the system, while many other arcade systems (in particular, from Sega and Namco) already used 3D playback tools. graphics.
