Maybe you should link the fix in the first post (or update the download folder)? Just to get people testing the newest version and not the old one.megavolt85 wrote:I hope now it will work, in any case, my freezes are gone

gdemu clone With the latest fix test. The game works fine on 3 stages, but has the same problem since stage 4 when I do the super move (as I mentioned before), freeze and repeating the character's voicemegavolt85 wrote:I hope now it will work, in any case, my freezes are gone

try to make a save state in demul if you can, when to execute and show the bug. the performance/bugs should be the exact same as the ones on real hardware to make it easy to fix.pentarou wrote:gdemu clone With the latest fix test.
