I managed to break bbakraid, it turns out yesterday the game didn't break because i increased its cpu clock, when you do that you get a "sound error" at boot and the game never seem to stop working, i can't seem to reproduce it after changing samplerate from 48k (libretro core's default) to 44.1k (standalone's default) either (edit: nvm, it finally happened), so i suppose the issue is tightly related to sound board emulation, it happened on both arm and x86_64. The issue i encountered seemed kinda different from what was reported though : the game seemed to keep rebooting while showing garbage for me, the game had some kind of huge slowdown right before that issue. I ran the game for ~15 minutes at x7 speed to get this.
Attaching a screenshot of the garbage screen and a savestate.
Edit : duration before crash seems very random, nothing in asan/ubsan, playing it safer on cflags didn't help either
