Hyperspin modified for RetroArch 32bit (aka Retroarch_ra32) in HyperSpin Android Posted July 31 2 hours ago, monoculero said: Ok, the parameters are incorrect. I have done some custom system, like cps, and these are correctly funcionals. The error was mine, because on retroarch the roms are working like a charm. Thanks for help. Happy to hear you sussed it out. Part of the reason I modded Hyperspin to use RA32 was so we got that Mame2010 core to use, it's missing in the 64 bit version of RetroArch. All the best with your setup, have fun with it!
