Here's a couple that annihilate JIT.
0.9.11 could handle them but nothing recent. I said it corrupts DynaRec but don't know much about any of that kind of stuff. Best I can do is follow instructions and use Google.

AR 1 021E55C000000000 ; No Random Battles (corrupts DynaRec)
what does "corrupts DynaRec" and "annihilates JIT" mean? I'm not sure you're writing about the problem this issue is about.
If I have JIT enabled with that No Random Battle code then the game is unresponsive. Moving across the world map pauses for a couple of seconds then picks up and pauses again. I don't know what the terms mean just that JIT has to be off if that code is on otherwise the game is unplayable.
Doesn't happen in Retroarch, just desmume/src/frontend/posix.
Just In Time always sounded like Dynamic Recompilation to me anyway - like they're synonymous.
ok, that does sound like the bug we're talking about here. Here's what you should have said: "Here's an example of thrashing the JIT: enable no random battle code then walk across the world map. Youll see the game bog down when the random battle is suppressed"

This code causes the JIT to reset each frame, since it's fighting with the game. Ideally only the affected jit blocks would be reset, but I only know how to reset the entire JIT.
I TRIED to reset only the affected blocks, but it didnt work; so maybe all self-modifying code is actually broken? Or maybe I did it wrong.
