Capcom Play System 3 (CPS3)
Capcom Play System 3 (officially short for CPS-3 ) is an arcade system developed and introduced by Capcom in 1996 with the game Warzard (known outside of Japan as Red Earth ).
The CPS-3 was the last arcade system developed by Capcom. The system used the following copyright protection mechanism: games were shipped on a CD with encrypted game content, and a special cartridge containing the game's BIOS and a SH-2 CPU with an integrated logical decryption system and a game key stored in a 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 falsification, 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 it was necessary to change it in order to continue working. 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 (notably those from Sega and Namco) already used 3D graphics playback facilities.
