ARM as well? Does disabling any of the Comp* files help (swapping CONDITIONAL_DISABLE defines)?

Where is in the file ?

Test in lg nexus 5 also work in interpreter .

Well, what I meant is, if it's a jit bug, it may be specific to x86jit (e.g. it may work fine on ARM with jit enabled.)

Anyway:

ppsspp/Core/MIPS/x86/CompALU.cpp

Line 40 in 27870aa

//#define CONDITIONAL_DISABLE { Comp_Generic(op); return; }

If you swap the CONDITIONAL_DISABLE define lines there, it'll disable the parts of jit in that file. Most of the Comp*.cpp files in that same directory have this. If you turn them all off, jit is "basically" disabled, except the core mechanics of it.

If it doesn't work even when everything is disabled, it's a "core mechanics" problem. If it does work, then it's a matter of narrowing down which file. I described this in that One Piece issue.

I swap in CompALU.cpp,CompVFPU.cpp,CompFPU.cpp,CompLoadStore.cpp
I get a crash strace.

Hmm, it seems to be reading a vector to 0.

ReadVector((float*)Memory::GetPointer(addr), V_Quad, vt);

So, seems like it must be related to jit mechanics...

You must follow rule:1 game 1 issue
btw:This game first you need disable JIT,
Then in-game enable JIT

Yes, it works.
But you shall switch, very quickly the lever in home position (JIT).
After arrival to the finish.

JIT = ✔
