Can you get custom firmware from another 3DS and put it on your 3ds? eg: if I get 11.3 on his 3ds and put the .cia on my 3ds will i have 11.3 or 11.4 still???
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
