Hi. Memory split is 256M for vram. I used to have it at 384M but decided to scale back because I thought that the games might be running out of memory (I checked later and that wasn’t the case)
The freezes happen randomly. I played Ocarina of Time for 4 hours with no problem, but when changing games it happens more rapidly. Try playing a little of more. Usually, the first game I start is stable, but when I change game, the freezes occur faster. Even shutting down an emulator and starting it again makes the freeze occur more rapidly. I hope it helps.
If there’s anything else I can do to help you pinpoint the issue I’m happy to help. Just tell me what files to provide for debugging.
