Here are a couple of scans from Marukatsu 93 Vol 01 Marble Madness http://img853.imageshack.us/img853/2021/marblemadness01.jpg Off the wall http://img222.imageshack.us/img222/4249/offthewall01.jpg
Marble Madness has been announced in september 1991 and delayed until 1993. It seems a few prototypes of Off the wall have been released, but I guess it hasn't been dumped yet. The development hasn't been completed.
It seems Off the wall was planned on Game Gear too: http://www.atariage.com/forums/topic/166942-unreleased-game-gear-proto-off-the-wall/
