afaik .z64 roms dont work as well as the .n64 roms in this emulator. Sometimes for games that work flawlessly in .n64 just crash in .z64
Wasn't z64 the only way to boot up a rom on vanilla 0.2? I had to convert all my backup roms to z64 because of it. I'm confused. Did not start DX64 in months. However that would kinda explain a lot of freezes lately I have?!
