Everything including PS2 and Wii (upscaled to 2 or 3 times the resolution), as well as 3DS. It runs Android, so any play store game will run as well.

I've lived too long with Bonk's Revenge as the only pcengine game I know. I'll definitely check it out! Thanks!

Is anyone able to name all these? I'm trying to get into shmups and would like to know more about the ones on pcengine 😄
