The CPS-1 system is an "A" and "B" board pair. The B-board contains all the actual ROM data for the game. You can swap any B-board onto any A-board. There are some differences in A-boards, however. For instance, Street Fighter II Turbo Hyper Fighting has a faster clock, so if you put it's B-board on a slower A-board, it will run slower. The clock speed is printed on the oscillators on the A-board, so you will know.

The board uses no encryption, unlike the CP System II.


Some games that use this system have "suicide batteries". When these batteries die, the game will no longer operate. A hack exists to revive these games, even if both batteries are dead. The hack involves burning one or more new EPROMs, using the c-board from a different CPS-1 game (one that does not have a suicide battery), replacing the custom Z80 with a standard Z80, and with a few of the games, adding a couple of TTL chips and doing a bit of soldering. The CPS-1 games known to use suicide batteries are King Of Dragons, Knights Of The Round, Three Wonders, Captain Commando, The Punisher, Saturday Night Slam Masters, Cadillacs And Dinosaurs, Warriors Of Fate, Quiz & Dragons and the Japanese version of Varth: Operation Thunderstorm.
