I have tried everything. All ROMs are AES and work with BIOS on Retropie PC and RP3 with no issues. However when I use the same ROM's and BIOS in Botocera x64 PC, I seem to have an issue where there is sound, a black screen and no way to exit. I have tried "Libretro" with "FBA" core as you are supposed to do. I have also tried the other cores however those are unsuccessful too. There is no way to exit out of the black screen unless you power the machine off.
Any suggestions would be great. Thank you.
