Thank you so much for the kind words and the compliments! I really appreciate you taking the time to test the game and report this. I’m glad you're enjoying the fork! I will look into those level-loading crashes and try my best to get them fixed for v3.6.
Thanks,

Sonic Superstars compat row (#12); CB4 video-state instrumentation
Raise guest RAM to PS5-like 12.5GB, capped by host memory
Coder787-source commentedon Sep 23, 2026
Hello @ztaxEvador, v3.6 is live! This build should help Sonic Superstars get closer to playability. However, I don't have this game myself, so I couldn't test it directly - your retest on the new build would mean a lot.
Thanks,

It still crashes here's the log
crexception.txt
runtimeLinker: dump last stubbed imports called in the AV handler
runtimeLinker: detect host-pointer leaks into guest registers on AV
runtimeLinker: add Superstars crash-class dump + fix stub-log flushing
runtimeLinker: route stub-call logging through LOGF (crash-file visible)
Coder787-source commentedon Sep 24, 2026
Hello @ztaxEvador , v3.7 is live - could you give it a try?
I can't guarantee this fix resolves the crash on its own, but the crash diagnostics in this build are much sharper: if it still crashes, the crash file will now name the exact mechanism (the missing function's NID and the fault class), which points directly at what to implement next. Either result moves us forward.
Thanks,
