How to donwngrade PPSSPP to v1.5.4 (solved)
-
@stumcbill I don't have a pi4 to do that for you but presumably yes you can. install that "first official" version of Retropie for rp4 on some sdcard, copy the same folder as I did and voila. If you only have one sd card back it up using some software like win32diskimager, install the "first official" retropie, copy the folder, restore your original sd card using the backup, and voila
@BuZz and others intersted in this.
Here's some footage comparing the currently available binary (f1a3ba7) and the 1.5.4 one on a Raspberry pi 3 (non b+). Same Iso, same settings, same SD card, same Retropie version, etc. (sorry for the shaky patato cam footage)If more footage or discussions is needed about this I'll probably use the github ticket from now on.

@buzz Can I use this somehow to install the older version directly from RetroPie?
-
@stumcbill update retropie-setup script, and it’s available in optional packages.

I’ve done that, and I can’t seem to see it. I’ve still just got the option for ppsspp and lr-ppsspp, both which (installing from binary) install the latest version?
I’m using a pi4 if that makes a difference?

Yes, it does - the older version is for Pi3 or lower. Do you have issues with the default PPSSPP emulator ?
-
@mitu yes, when I installed the first version of RetroPie for Pi4 (4.7 I think), Ridge Racer and Ridge Racer 2 ran almost perfectly. Since updating my RetroPie install they are both unplayable so was looking to downgrade if possible.

@stumcbill PPSSPP Version 1.5.4 is from 3 years ago, so I don't think your issue is similar to the one in this topic, given RetroPie 4.7.1 was released this year and it's using a much recent version of PPSSPP.

Ah ok, is there anyway I can reinstall the version that comes with 4.7 to see if it makes a difference?
I might backup my installation and reinstall 4.7 (if I can find it anywhere).

Since PPSSPP isn't installed on the 4.7 image by default, even if you download the 4.7 image, installing from binary will still get you the current/last version. So, no - you can't reinstall the old version from RetroPie-Setup.

Ah, I never realised that. Sounds like I’m out of luck then.
