I downloaded a game from itch.co and it was a .d64 file, it's a Vic 20 game. It plays fine with the Vice emulator, so it seems to have all the correct files.

Do I need a bios?

I am using Vice with the xvic.exe. I get ?UNDEF'D STATEMENT ERROR when I try to run them.

I'm trying to set up Vic 20 roms with Vice through Launchbox. The rom set I have the roms are .60, .20. a0. Vice doesn't launch them. Do I need a different set? Thanks for you help!

Works perfect!! Thank you!

I checked them, they are large .iso almost 7gb. When you say file format is that all the separate files like .wav, .sfd, .dat files in one folder? I have those as well as the .iso.

I am using Xemu. Most of my Xbox games load. Everything is in the .iso format. I have also got ones that are .xiso.iso. The thing is there is a section of them that won't load. What I mean is it starts with Night Caster and goes through Outrun. Those 2 and anything inbetween won't load. I get the insert an xbox disc message. The games in that run are Night Caster, Night Caster 2, Oddworld: Munch's, Oddworld: Strange Wrath, Outlaw Golf 1& 2, Outlaw Holiday Golf, More holiday golf, Outlaw Volleyball, Volleyball Red Hot and Out Run. Any help would be great! Thanks

I am trying to boot Jaguar cartridge games. They boot to a black screen and nothing happens. The CD games play fine. I am using BigPemu.

Changed to Vulkan. Seems to be working great now!! Thanks!

Got it, will try in the morning. I will let you know what how it works. Thanks!

Where are the settings?

Just tried the Blastem Core with the same result.

Yes, all the bios are present. All the roms will work for about 5 minutes and then Retroarch closes. Is the Genesis Plus GX stable? There are several cores, I'm not sure of the difference between them.

The Genesis emulator I am using in Retroarch is Genesis Plus GX. The roms play fine for a bit and then they crash. It happens on all the Genesis roms. Not sure why. I have attached the log.
