Medarot 2 - Parts Collection is one of those weird little Game Boy Color spin-offs that only makes sense if you're deep into the main game. It's basically a trading tool for Medarot 2—lets you swap robot parts between cartridges using the link cable. Not exactly a standalone experience, but if you're trying to min-max your Medabots, it's kinda handy.

Just don't mix it up with Parts Collection 2 (yes, that exists), since this one only works with Medarot 2. The whole thing feels very late-90s Japan—obscure, slightly janky, and weirdly charming if you're into that era of portable gaming.
