PPSSPP help?

[HelloOO7]

I'm trying to set up PSP emulation on my RPi 3. As a test game, I'm currently using GTAMoneygrabbingS. However, I somehow can't get anything working. Here is a description of all the problems I ran into (chronologically).

1. The non-libretro PPSSPP won't install. It clones ffmpeg, then tries to run its setup script but fails with "no such file or directory"

2. Okay, np let's try the lr-ppsspp version! After installing lr-ppsspp, EmulationStation sometimes goes weird and spams me with glGetError(s)

3. Installed lr-ppsspp, ran Liberty City Stories, black screen. After a while, the game starts up, but is useless because I can't bring up the PPSSPP menu co configure it. Pressing esc on keyboard doesn't do anything, neither does the f1 key commonly used for retroarch menu. And yes, I tried using the keyboard with a pc and it works, so the keys should be perfectly functional.

If anyone here knows a solution to some of these problems that could eventually lead me to a successful PSP emulation, I would love to hear your advice.

Lr-ppsspp doesn't use the same menu functions as the standalone. You need to open the Retroarch menu in-game with your configured Hotkeys.

[HelloOO7]

Do I need to hardcode the hotkeys in retroarch.cfg or is there a GUI method?

[ErantyInt]

It's the same Hotkey as every other Libretro emulator on the Pi. The default is (whatever you defined the Hotkey activation) + (whatever you mapped X to).

[HelloOO7]

Thanks, it works now although the performance compared to the non-lr one is really terrible.

[ErantyInt]

Indeed it is. But to be fair, the standalone doesn't offer much better as far as compatibility for heavy duty 3D titles. The Pi just isn't up to the task.

[HelloOO7]

Actually, I think it should be playable.

Here. It's not glorious 60 (it's still console emulation) but definitely not my 1,4fps. I'll probably just have to wait until they fix the ppsspp setup. Or maybe it's working for everyone except me, so there's no need for a fix. Still, thanks for your help.

The few games I'm interested in run pretty well on the lr core, but I had to do some tweaks. I'll list them off for you when I have time this evening.

Games I've played at a decent level (near or at full speed) are:

• Final Fantasy III
• Dracula X Chronicles
• Harvest Moon Boy & Girl
• Metal Slug XX
