I usually use SNES9x but it wasn't working with hacks, as in the roms froze after a bit and the sound went off, which all SNES emulators did on my old computer. But when I use ZSNES, it still has that weird muffling that happens to the spin dash and other sounds. How do I make it so the sound syncs on ZSNES?
The ROM is probably corrupted. Use a clean rom when patching. Or are you opening the IPS patch. ''
Check if the ROM you are using to patch the IPS patch, is clean here.
Also, if its keeps on happening, the game you are currently playing, is bad. Something is causing it to crash, in game, not your computer.
