I’m not seeing anything on their websites for how much power it needs to run. I’m guessing the pi isn’t powerful enough for it, but if you can get it installed from their github (where everything is 1.1, but you have to install from source) here: https://github.com/hrydgard/ppsspp
If you can get it running it would be awesome! Please give it a try and let us know.
Please. Compile it and make a guide for us, or at least link to a guide already up. The guys on Retropie are busy on other things in improving this for us all, so making it easier for them is always appreciated!
I’m unfortunately overencumbered with projects to do it myself currently, or else I’d do it.
