So i was wondering if these changes will ever be ported to the core?
Also, what’s the state of Mupen 64 core? Last time i checked, there were stuttering problems in some games (Mario 64 tested). Gonna test it again tonight.
Edit: Just tested the latest Mupen Core. Mario 64 still has stutters 
I couldn’t backport bsmiles changes, which moved a bunch of stuff around, but I can probably cherry-pick logan/jamman’s changes. I’ll try to work on it some this weekend.
The stuttering you’re just going to have to live with until we can get around to reconciling the fix with the crashes that were caused by the same commit (maybe not related to the actual fix, but we’ll have to look into it to find out).
