You're right - it's a two-fold problem. I did a few tests and played through the opening area of Turrican 2 a few times with different settings. I found that 50hz always jitters, but 60hz only jitters at high audio quality settings. If I drop audio down a notch or two to 22k or 32k then the...
Hmm - I still get the jitter even when I set the refresh to 60. I can see the fps change in the status line, but the jitter only goes away if I disable sound.
Great emulator - it's almost perfect! Been having a lot of fun with it.
50fps games (Turrican 2 and Apidya are good examples) suffer from jitter. I think it's a performance problem as the jitter goes away and the game updates perfectly smoothly if I disable audio.
Also, some games are offset...
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
