just today i got e[mulator] for psp and when i open up a gameboy game, go into the menu and press "save state" all of the slots are grayed out and when i click on them nothing happens. the game plays completely fine btw.
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
