The only console version I know is the Nes one and I haven't explored it much.. I'm more familiar with the ST versions but the two are not too far apart graphically. I wouldn't like to have to design as many levels as you could possibly fit in though! ;)
I'd like to have a go at re-creating the Nes sprites and movement routines on a test screen. If I got something like that working would it go some way towards helping if combined with more graphics and your map ideas?
