PPSSPP iOS Port

[infernoxzx]

There is progress with Jit(dynarec)?

[rock88]

I modify Jit::RunLoopUntil function to

Code:

void Jit::RunLoopUntil(u64 globalticks)
{
    // TODO: copy globalticks somewhere
    mprotect((void *)enterCode, 1024, PROT_READ | PROT_EXEC);
    ((void (*)())enterCode)();
}

I do not know correctly it was to do, but now app crashing in other function, log -

did you give it root access?
EDIT:also any idea why it is grey like this everytime i build it
   

[Henrik]

It's grey because it can't find assets/ppge_atlas.zim

I didn't read the whole source, but you have to see if there is any file which calls ppge_atlas.zim, with all of these mods you made to the source trying to get JIT working it maybe have been lost

[rock88]

the avenger,
See my previous post
Also you can add some printf function to VFSReadFile in native/file/zip_read.cpp, for print full file path, and view if something is wrong.

I have managed to get crisis core working on iPhone. I have screens if anyone is interested. I don't no much about emulation (backend anyway) but if jit gets working on iOS then this game will run pretty well

[xsacha]

The mprotect function you gave removes the PROT_EXEC flag. So now it doesn't have permission to execute (which defeats the purpose).

Yes, crisis core works.

Merged your assets fix rock88.

Just saw this in git builds list "Fix iOS assets. Thanks rock88".The cydia repo is not updated so where exactly do all the iOS fixes go?

@the avenger

same question,so jit working now?

How to fix it?

[xsacha]

Try cleaning and then compile again.

And no, JIT not working. But it's nothing to do with PPSSPP. It's to do with packaging/how you run it. Needs to be done like other emus that use JIT (but I couldn't actually find any).

[brujo55]

actually any emu for ios using JIT.

---

i think maybe robert brogglia emplement JIT in future update for satur emu ios.

is possible to add custum frameskip [selectable 0,1,2,3,etc]
