CPS2, or the Capcom Play System 2, is an arcade system board developed by Capcom in the mid-1990s. It is known for its advanced graphics and sound capabilities, allowing for high-quality 2D games. The system was widely used for popular titles such as Street Fighter Alpha 3 and Marvel vs. Capcom. The CPS2 features a unique security system that uses encrypted ROMs, making it difficult to pirate games. It supports multiple games on a single board, which was a cost-effective solution for arcade operators. The CPS2 was succeeded by the CPS3 system in 1996, which introduced 3D graphics.
