I commented recently that I adore this initiative to have a kernel which boot emulators super fast. If you read my blog you know that Richard Howell is doing that happens, but some users are not cleared with the method to copy the boot and root. For them I have prepared a .img file of 140 MB size only for you to try it...
I loaded two homebrew games for SNES and Game Boy Advance that are completely legal. If you want to add yours, put inside the /usr/share/roms folder.
