ok, so basically i have a issue. I have luma3ds flashed to the ctrnand there is a boot.firm file in there. Although if i remove the SD card, it shows a ARM11 undefined instruction error. I am not a amazing modder so i do not know how to fix this. Although it boots with the SD card perfectly...
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
