[Linux | JIT | DeSmuME 0.9.9] Can't have battles in Pokemon Black 2.
[Linux | JIT | DeSmuME 0.9.9] Can't have battles in Pokemon Black 2.
When JIT is enabled, the game is speeded up but it will crash whenever a battle begin. Turn JIT off, everything's alright but the speed drop down.
Hope it can be fix soon.
This what on my terminal.

It doesn't work. The same error.
Decrease the jit block size to 1 or 2, still the same.
The jit block size = 15 has some differences. Instead of crashing, the game freezes with black screen, repeat sound and no error report in terminal.

You're experiencing an assert() termination, which is caused by emulation errors on the JIT engine. Normally, assertions are disabled in release builds, but this doesn't seem to be the case with your build. You will need to disable assertions to avoid this type of program crash.
You should be able to disable assertions by recompiling DeSmuME with #define NDEBUG.

I tried to add the line
#define NDEBUGto arm_jit.h and recompiled DeSmuME.
Now I can enter battle. But when the battle's ended, I have black screen with no sound. Pause then run the game still varies the frame rate.

If I load the savestate that has been saved before the battlefield appear, I will have the black screen.
But if that savestate has been saved after the battlefield appear, there's no error when battle end.
So I have the temporary solution for myself.
1/ Begin a battle.
2/ Wait for the battlefield appear.
3/ Savestate then immediately loadstate.
4/ End the battle without problems.
These are the savestates of two battles. Each battle has 2 files, one before and one after the battlefield appear.
