Play! is a Work In Progress PlayStation2 emulator. Thanks to the great efforts of Zer0xFF, who took three days out of his busy schedule to port the emulator to the libretro API, we can start rolling out this emulator to our buildbot soon!
It must be stressed that Play! is a Work In Progress PS2 emulator, and we mean that literally. Don’t expect every game to run perfectly, far from it. However, it has a solid foundation and already has working dynamic recompilers for all the popular architectures, its value which cannot be understated. The libretro core also already has working savestate support.
This core will require OpenGL on the desktop and OpenGL ES3 on mobile devices.
Game compatibility is entirely dependent on the state of the upstream #Play! emulator. So as Play! improves, so too will the libretro core!
#Libretro is currently a Patreon backer of the Play! project, and we are very grateful to Zer0xFF from the Play! project for getting this port up and running in less than 3 days! Good open source PlayStation2 emulation deserves to get more funding, and we are happy to do our part. We hope you will as well!
Note too that the PCSX2 core bounty is still alive and well, and can still be picked up by any developer willing to port it to the libretro API.
