I remember hearing about Kid Chameleon here and being sure I'd seen a game about a kid who turned into a chameleon on the NES at some point. I think this is what I remembered (badly). I think it's that cover art that confused me. In-game, the kid turns into a frog man rather than that lizard (among other things). Now I've got to pick this one up.

It was a rather insane translation wasn't it?

That '80s to early '90s style is great stuff in retrospect, though. :)

Holy carp, I remember that cover art. Can't say I've ever played it though. Someone emulate it and tell us if it's any good.
