One of the more recent developments is the addition of Capcom CPS-2 titles. Jotego, the developer behind this project, has now stated that the entire CPS-2 library will soon be playable on the handheld:
CPS-2 was Capcom's arcade-based successor to its popular CPS-1 system, and was home to titles like Super Street Fighter II, X-Men vs Street Fighter, Aliens vs Predator, Marvel vs. Capcom and Progear. You'll need to be subscribed to Jotego's Patreon to gain access to these cores.
