Description

in r3110 first time was fixed Sonic Unleased loading screen hang bug after
it it was fixed properly in r3312 but these changes to
Jit_FloatingPoint.cpp in fcmpx instruction causes very rare hangs to
Metroid Prime 2
removing DENToZero fixes this hang but makes Sonic Unleased broken again
Here's the MP2 save which is closest to
issue place http://depositfiles.com/files/dfm16ihq1
and the video that sows how to rech the bug

***I have no bug in the video cause i prefer MP2 ove sonic games and play
without DENToZero

Forgot to mention this bug is JITIL only, normal JIT works fine in both cases

Ummmm... Metroid Prime(U) hangs for me in a corridor right before the Power Bombs,
when passing by Phazon Mines... I thought my Disc was screwed up, but it works on my GC

More info
i tested Sonic on last revs without DENToZero in fcmpx, and it seems it no longer
hangs at loading screen thanks to last FPU changes i think, game still have hangs
but it's not related to this issue

Yeah, it still freezes for me in that corridor. Also, Twilight Princess freezes for
me on the cutscene after defeating Morpheel...

found something interesting (still testing):
I'm also trying to play Sonic Unleashed, but with normal dolphin, Hang at loading-
screen + 0 FPS. dolphinIL hangs short after loading-screen.
The first one who posted a problem like that (Issue 398) has a AMD Phenom CPU.
I'm using an AMD Phenom II X4 940.
On the PC of my little brother, the Game stops at same places (he has an AMD Athlon
64 X2 4200+).
I tested the Game with the current Versions of dolphin, but no luck till now.
But: I tested the Game on my Notebook (Intel Core2Duo P8600) and the Game has no
problem (only lagging^^).
So far I think it has something to do with AMD CPU's...
