Capcom Play System 2 Roms
Capcom Play System 2 System Information
The Capcom Play System (CPS-2), was a powerful pice of hardware developed in 1993 by Capcom. It was the hardware that games like; 1944: The Loop Master, Marvel Super Heroes, Marvel Super Heroes Vs. Street Fighter, Marvel Vs. Capcom, Pocket Fighter, Street Fighter Zero (Alpha) 1-3, Super Street Fighter *, The Vampire (Hunter) / DarkStalkers series, X-men: Children of the Atom, X-Men VS Street Fighter, etc. were based off of.
It should be noted that the CPS-2 system had complex-encryption methods used which were initially used to prevent cartridges from being easily reproduced and pirated, however an off set to the complex encryption\decryption scheme has caused great trouble with emulating the games through emulators such as MAME. Also a method known as “CPS-2 Suicide” was implemented where by if the machine is unassembled the connection to the lithium battery would most certainly be lost causing the decryption keys to be lost from the S-RAM located inside one of the onboard custom chips, thus making the board a paperweight. The bad (and perhaps unintentional) side effect is that eventually over time the board would just die anyway, meaning even if you were using it legally you could not play it after a finite amount of time (unless you paid Capcom a fee to replace it that is...).
