For sure it is doable in MSX1, but in this case I wouldn't
see any real improvement with respect to the original game,
and I have already an intellivision emulator to play at it
The port in MSX2 would be great, even using scr4 for the dungeon.
I think that scr5 whould be also doable but a much more
difficult as the scrolling should have at least two speeds.
