This is an edit of TuxSH's usr2arm9ldr, which in turn is a standalone and sane implementation of 2xrsa. The source code was modified to work with OoThax. Use with the gspwn ARM11 OoThax savegame.
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
