The or Capcom Play System 2 is an ''. HISTORY The earlier Capcom System Board , CPS-1 , while successful, was very vulnerable to bootleggers making unauthorized copies of the games. In order to rectify the situation, Capcom took the CPS-1 hardware (with QSound) with minimal changes and employed encryption on the program ROMs to prevent illegal copying. The CPS-2 consists of 2 separate parts; the ''A'' board, which connects to the JAMMA harness and contains components common between all CPS-2 games, and the ''B'' board, which contains the game itself. The relationship between the ''A'' and ''B'' board is basically the same as that between a home video game console and cartridge. CPS-2 ''A'' and ''B'' boards are color-coded by region, and each board can only be used with its same-colored mate. The exception to this is that the blue and green boards can be used together. The ''B'' boards hold battery-backed memory containing decryption keys needed for the games to run. As time passes, these batteries lose their charge and the games stop functioning. This is known to hobbyists as the "suicide battery". It is possible to bypass the original battery and swap it out with a new one in-circuit, but this must be done before the original falls below 2V or the keys will be lost. Due to the heavy encryption, it was believed for a long time that CPS-2 difference tables to produce this data from ROM images, making emulation possible, as well as restoring cartridges that had been erased because of the suicide system. The legality of these difference tables is disputed. In . Also thanks to the encryption, the system was never bootlegged until unencrypted program data became available. SPECIFICATIONS
