I have retroarch 1.7.0 and Launchbox premium. In my emulator settings I have "extract rom archives before running" checked. All of my roms are redump and 7zipped. For Saturn and Playstation I use mednafen core. I can run my 7zipped playstation games from launchbox without any trouble. However, when I try to run sega saturn I get the little progress circle mouse pointer thing and then nothing happens. I extracted the same sega saturn games and ran directly from retroarch and they run just fine (I have all the right bios files in the system folder). What do I do get this running properly?
