Now here's something you don't see every day. Thanks to Dano2k0 of the Assembler Forum, we now know that Rare was developing Jet Force Gemini for the Game Boy Color nearly a decade ago. According to the screenshots uploaded by Dano2k0 (which was a "Cheat Version 2.3," whatever that means), the game looked to be from a top-down perspective, much like PD GBC. Juno seems to be initially playable, yet if the N64 version is anything to go by, it's reasonable to assume that Vela and Lupus would be playable down the line. In regards to the cart, Dano2k0 mentioned that the game "actually seems somewhat complete in terms of sound and menus."
