can someone tell me the name of this thing, I forgot

It was some little cheap mini game system that I think only played pokemon LCD games. They could be bought at new york pokecenter and I think they were about $10 or $20 for a game or maybe there were mini cartridges and they were $5? I think there was a chansey game, and some other ones. It came out around the same time as Pokemon Channel Gamecube game (maybe)

I believe you're thinking of Pokemon Minis. Not too sure though, since during that time, I didn't have anything of the like or any way to go to the Pokemon Center in NY. lol

This is what Sydian was referring to. Is this it?




I believe this is it. Here is a link about it.
