So while saving the game in Mario & Luigi: Partners in Time, it freezes to "Saving File. Do not touch the Power Button or remove the Game Card."
It actually saves, but it just freezes to that part.
I have the latest version of AKAIO.
Not sure about other models of Pi4 but the Pi 4 B with 8GBs OCed to 2Ghz handles PSP really great except like 1 game I found and it is playable it just looks bad lol Motor Storm Arctic something or other.
