Game Boy Pocket Compatibility: Only Original Game Boy (DMG) Cartridges

The Game Boy Pocket only plays original Game Boy (DMG) cartridges (gray, black, or gold labels). It cannot play:

• Game Boy Color (CGB) exclusive games (clear/black carts with "Game Boy Color" logo).
• Game Boy Advance (AGB) games (half-size carts).

Why?

• Hardware: Pocket uses the same Sharp LR35902 CPU (4.19 MHz) and monochrome LCD as the original DMG. It lacks the Color's faster CPU, VRAM, and color palette.
• Cartridge Slot: Physically accepts CGB carts (same shape), but the software handshake fails—game either shows "This Game Boy Color game cannot be played" or glitches.

For Color/GBA games, use a Game Boy Color, Game Boy Advance SP, or Nintendo DS/DS Lite (GBA slot).
