I like your custom build of Luma. If you don't mind a suggestion, you should try to remove the autocopy of the boot.firm to the nand. Don't know why they thought that was a good idea.
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
