A Novice needs HELP!

Hey guys,

So heres where im at:

Have an Old PC (2011 HP) that im trying to make into an incredible retro system. I can get SNES, NES Master System, GBA, GB, SEGA Genesis & SEGA 32X games running, No problem. However…When i get to N64, PSX, Neo Geo, MaMe or anything more advanced, I fail completely. I can detect the content but when i go to run it, I get a black screen with the Lakka Logo then it kicks me back to the main menu, BUT after that i cant run any thing and need to completely reinstall LAKKA and all the Roms.

Whats going on? How am i failing?

A ny help is GREATLY appreciated

PS: I’ve wiped all other OS’s off the PC and am strictly trying to run Lakka

Not an expert but have you located the BIOS files correctly?
