Nah... I've lost my hope... Nor even my brother - who used to play the game with me - remembers the game's name, just like my friends.... and we searched our old (and useless) msx disks... searched all the net sites... wasted hours testing roms in msx emulators... for nothing.
Anyway, what about "The Reap"? I downloaded a demo version a long time ago. But never had the actual game. And never found it anywhere (it was quite big wasn't it?).
