i'm having a issue with the emulator, when i use some cheats from DeSmuME database and have the option dynamic recompiler enabled, the fps on the games drastically falls, as example, i was playing Castelvania Order of Ecclesia and when i enable infinite double jumps or infinite jumps, or other codes that alter in game option, the fps falls making the game unplayable. The same happens with Castlevania Portrait of Ruin, when i toggle the cheat infinite luck and try to change the equipment, the game almost freeze. If i turn the dynamic recompiler option off, this issue doesn't happens, but i can't play any DS roms on full fps.
I'm sending a image to exemplify the issue.
Thanks for the attention.
Beste regards.

It could be fixed by invalidating every basic block backwards from the patch address, up to "jit_max_block_size" rather than flushing the jit entirely. The thing is, this should have been easy, because the jit needs to do it internally for self-modifying code. However, it doesnt appear to be functioning properly. For instance if you look at the end of _MMU_ARM9_write32() you will see that only two instruction slots are cleared when the memory is written to. Shouldn't it "invalidate every basic block backwards from" the address? This makes me doubt some of the fundamental internal integrity of the JIT. Now, since it's slow, the cheats WORK, even if they're slow. If I try to make it work properly and the foundations are wrong, then I will fail to make it work properly.
This needs attention from someone who cares about jits. I do not want to take custody of maintaining desmume's JIT.
How do you use cheats on the linux version? I just switched versions and the cheats Action Replay button isnt there. How do you enter the cheat code itself?
