Been setting up my collection, and one system giving me problems is the Saturn. Games booted through yabuse core, however most were not emulated properly (VF1 physics were off, instant ringouts, VF2 had no sound). Tested the same games on Beetle through Retroarch, and all launched and ran properly. Problem is, games set to launch with the beetle core through launchbox just don't open. The big box launch screen pops, then nothing, back to game select. Is mednafen_saturn_libretro not the Retroarch Beetle core? I should have the correct bios files in the right place, as retroarch launches properly. All games are set to launch the cue file, directories are named right, kinda at a loss for words. Any help?
