A Pokemon Leaf Green 386 hack I did myself with minor changes (including starting with the National Dex ) Be sure to read the Notes.txt file BEFORE you start playing the game! Apply the patch to a clean US version Leaf Green rom (release #1637)
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
