There is no "Pokémon Trading Card Game" for the original Game Boy (DMG, Pocket, Light). It was released exclusively for **Game Boy Color (GBC)**.
A faithful adaptation of the Base Set / Jungle / Fossil / Team Rocket TCG rules. Story mode: travel islands, defeat Club Masters, collect cards, build decks. Includes **link cable multiplayer** and **Card Pop!** (IR trade with another GBC).
If you have a monochrome Game Boy, it won't run. You need GBC, GBA, GBA SP, DS/DS Lite (GBC mode), or emulator.
