I hope I don't derail the thread, but I feel like this is an opportunity to ask about a couple of games myself:
How are the two PSP Valkyria Chronicles games and do they perform well on PPSSPP? Preferably Android (Snapdragon 670, Adreno 615, if that helps), but PC is fine as well.
I really enjoyed the first on PC and bought IV ages ago, but I haven't played it because I kind of want to play the others first (which were never ported to PC or any other console for whatever reason).
From what I understand, all the games are more or less self-contained, so I can play IV without missing much but I'd really like to give II and III a shot if I can.
Lol, I saw the same thing when I hopped onto F-Droid.
I think the better options there are probably RetroArch or Lemuroid, which seem to be better maintained and can both use PPSSPP as the backend (though I think you need to add the libretro core for the emulator in RetroArch).
Hopefully their versions of PPSSPP are more up to date, but I'm not certain.
Edit: Actually best option seems to be the official site where they have a standalone APK, so you don't need to use Google Play (also, there's no difference between the "Gold" and regular version, it's just an option if you'd like to donate).
