Any help?
That log doesn’t tell us much. Try launching from a command line with --menu and --verbose. It will print any errors to the console window.

Have you tried an NTSC version of the ROM? Conker is notoriously temperamental but I seem to recall some people getting it working…
I tried like 20 different games, not a single one is starting.
Are all of them in n64 format? I think the libretro core only supports v64 ROMs…?
n64, z64, rom, v64 nothing works
It’s working fine in linux but I went to test in Windows and i’m getting the same behavior you’re describing. I’ll look into it some more…
Under retroarch 64bit no problems at all, it seems the 32bit version is broken.
Last time I tested on my brother’s PC (loading roms from the same network share I use on my PC, so, same files), Mupen wasn’t working. The main difference was that my PC is using a x64 Windows, while theirs is x86 (32-bit).
I changed the mupen64-cpucore option and it worked (not sure if I used cached_interpreter or pure_interpreter, tho. And of course, it presents some compatibility and performance consequences, but since it wasn’t working before on that pc…
Mine was doing this too. But it was only a few different games. Now i can get them to load but they are so jumpy. Hope you got it fixed!
