Issue 5401 has been merged into this issue.

The revert is not a solution, is complicated because of Exceptions timing, the actual trick is not perfect, but help to ramdoms hangs because of pe exceptions

OK, thi issue is interesting and is related with VI timing.

Autoran could you make me a favor, please test your patch commenting beside these lines in coretiming, Can you reproduce the desync again?

while (g_video_backend->Video_IsPossibleWaitingSetDrawDone())
{
	ProcessFifoWaitEvents();		
	Common::YieldCPU();
}

Commented out these lines in CoreTiming, everything is pretty much the same way
There is desync without my patch and no with it

made more tests, my patch also syncronizes fps in Metroid 1&2 map rendering, and makes No More Heroes 1 much more synced, tested other games, no negative impact so far, will report if i'll find some

Thanks, autorun but your patch revert the commit that solves hangs in Simpsons, Monkey Isaland, etc is dificcult to explain here. The Exteranal Exception checking is not like the real HW, that affect the FIFO. I will try to find out a better workaround, but the perfect solution depends of PowerPC implementation. You can see the delroth commits in ARAM DMA branch trying to fix EE timing flag for example.

Thanks, marcosvitali :)
