lr-ppsspp crashes Retroarch when Save State selected

[PiperCalls]

What happens?

When Save State selected RA freezes/crashes. Tried several games, all same result. Note: all games tested are playing fine, just can't save. Assests from git are in place in RA/system/ppsspp.

What should happen?

Save State correctly

What hardware, operating system, and PPSSPP version? On desktop, GPU matters for graphical issues.

Samsung Note 8+
Android 9
lr-ppsspp (PPSSPP 07a5adc)

Not sure if related, but assets from git contain ppge_atlas.zim which has an md5 of (f46570c34bcf6a01cf20b93add725c3b) which does NOT match what the RA reports in core info (a93fc411c1ce7d001a2a812643c70085) as the correct md5.

Same issue here on a Samsung S7 but the crash/freeze is not systematic when saving state.

Same is happening to me on the Shield. It wasn't happening back in February though. Was that a different version? Can we revert to that version somehow?

There was a change made in #11990 which was supposed to make this work better on libretro. It's a hack though.

As I recall the problem is that libretro assumes all emulators will be single core, but PPSSPP is multicore. PPSSPP needs to create a save state when everyone has put their pencils down, or crashes may occur. libretro's assumption probably makes sense for NES and Gameboy emulators, but doesn't really work for a PSP emulator.
