whats meant by NOTE: For license reasons, these files are not in the SD image so you have to provide them yourself or download them elsewhere.
does that mean i'll have to find all those files he mentioned online and put them into those locations? im pretty new to this and what to make sure i have an idea what im doing. As in find duke.rts, duke3d.grp, game.con, ultramid.ini, user.con, defs.con AND gba_bios.bin of the internet and put them in said mentioned folders?
thanks OP for making this too!
