PPSSPP Problem

So i was running the ppsspp emulator and it ran everything including metal slug anthology . But i wanted to use retroarch but here is the problem. I was using this version i found RetroArch Master v1 an older one. It runs almost all my games but a few like my favorite metal slug anthology just loads a black screen. Whats the cause for the black screen? So i downloaded the latest retroarch cores to see if the new core would run metal slug and i get this message (look at image). Could some one please help with these issues?? Error message WrieRest: op out of range (0x7feea5448d uses 0x66da580) That is the message with the new ppsspp core. Please help with either core o i can play metal slug?

So i got all my games to work but 1 and that is metal slug anthology. When i start it starts to load then screen goes black and stays. It does that with any ppsspp core. But if i use the stand alone ppsspp emulator metal slug anthology works perfect. What could this be? I really want to use retroarch, could some one please hep?

It’s a known issue: https://github.com/libretro/libretro-ppsspp/issues/22

I’ve uploaded a 64bit build of the core from before that error started happening: https://www.dropbox.com/s/ojxrc6lvmqhh3os/ppsspp_libretro.zip?dl=0
