@mrayzarc I'm not sure, you have not even made it clear what Rpi you have, according to the Wiki, it only works on Rpi3 / 3 +, and slowly:
https://github.com/recalbox/recalbox-os/wiki/Board-Compatibility-(EN)
I do not know if it's all the games that run, I think not, and I've had problems with the PSP not working in the previous version of Recalbox, what I know is that it is not recommended to have many systems, because it overloads VRAM, and the theme should being at maximum resolution of 720p for the PSP to work.
Some people use PSP ROMs on a USB stick, so you do not have the problem of having many systems together ...
