I passed on a few Neo Geo carts at a thrift for $7 each. Nothing special. All I remember is a Golf game and a Baseball one.

I picked up a few sealed copies of some Bandai Pippen games at a swap for cheap. I left a lot behind though because they were more edutainment than actual games (well there was a Power Ranger game too but buying that one was just plain wrong to me then.

Another thing that is sort of along the same lines is at a CGE two years ago I was talking to a guy there that claimed to have a lot of Bandai Pippen equipment. Gave him my email address but never heard from him.
