PPSSPP is a really great psp emulator for Windows. It allows for custom controller configuration, including Xbox 360 PC controllers. It has HD display, it really has great resolution especially for a psp game emulator.
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
