It's been 2 months since I've lost my FF7 Crisis Core edition PSP 2000's battery cover, I swear to god it magically disappeared while I was taking my consoles out of the drawer...
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
And it's even better today because you can buy that storage expansion and install it without difficulty.
