Nice! I can safely say it works now. I've installed it on an external SSD, by reformatting it with 50MB partition in FAT32 at the start of the drive with the bzImage and initramfs, and the rest is an ext4 partition on a PC, and unpacking the tar on the ext4 partition. Everything works, but I've noticed a lot of graphical glitches in the UI, and especially, Minecraft Java runs well but all the UI and character textures are broken. Still, thanks for the work you've put into this, it's awesome!
