I used this editor many years ago. It had a really nice GUI where you could edit items in your inventory.
I one on 360haven is NOT the one I'm looking for as that one is really limited. Bruteforce has a few more cheats but the inventory editor doesn't work too well.
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
