PPSSPP iOS Port

[rock88]

Hi everybody!
Recently I have started to port PPSSPP on IOS Devices. After a couple of nights have run the first build on a iPhone 4s.





Since impossible to work on IOS with memory by ASHMEM, I always get a message "MemoryMap_Setup: Failed finding a memory base." And code in MemArena.c slightly changed, I took the code from Dolphin and allocated by mmap 64Mb memory.

Demo with cube work perfect. Puzzle Bobble show title "Please wait ..." and very often the screen flickers.

I think this is because that the main emu loop occurs during image rendering (mipsr4k.RunLoopUntil (nowTicks + frameTicks)). Are there any ways to run emu loop in background thread? I tried to run it in the background, but the result was the image flickers and no signs that the emulation is work not.

In the PPSSPP for Android video the Puzzle Bobble started very fast and works just as well as you might think, which is why in the IOS with this such a problem? May need to allocate more memory or, more importantly, as a default C++ compiler is not a GCC?

Testing device - iphone 4s, IOS 6.0.1, without Jail.
