I still remember having to save up GBQuid100 for my 1 meg expansion - the only game of note that needed it at the time was Dungeon Master - and when I finally got to play the game - I didn't really like it. Oh well.
As for my game - OK people, I get the hint!
Thanks to amigaboy for PMing me some feedback.
I suppose you can't do a retro game in 2003..
