Been messing around with the psx core, and so far so good, compatibility seems awesome, but the memory card issue seems so screw some gamee up. Basicly, the memory card doesnt seem to be persistent, each game appears to use their own, and using savestates will somehow make it look like a different memory card after loading a stavestateonce. Example in spyro 3 follows:
Retroarch will then crash after about 3 seconds, on an ipad 4. I’ll check if its just a bad rip later using pcsx on my pc. Anyway, tekken3 seems to work fine, and so far no problem on metal gear solid (tho i haven’t saved there yet, no clue how i’ll get from CD1 to CD2, maybe using VGui)
