Someone would need to first get it, send it to the correct person and check if it can be dumped though.
Grandstand - Ghostcatcher? I never heard about it, however I did own two LCD games as a kid and one was ghost themed. Turns out it's a bootleg from this one apparently. It was called Ghost Buster. I found two videos from them.
I loved that game (along with Car Racing -another bootleg-). I never owned a GameBoy or a GameGear, so these games were my favorites when I wasn't playing my Sega Genesis (or was it my Atari 7800?, I can't remember how old I was).
I would love to see it on MAME someday, but even if the original doesn't show up I'm sure some of the bootlegs will at some point.
