This system has always confused me, I never owned one back in the day and it wasn't until I started playing Zelda DX on the 3DS this week that I even played a GBC game.
Can someone please answer the following?
1. Why are its sales counted as 'Game Boy' sales? Isn't it a new system all together? According to wikipedia it has a 8MHz processor compared to the original Game Boys 4.19MHz (faster than the SNES 3.58MHz wtf?) as well as various other improvements.
2. How the hell are some (the black carts) playable on original Game Boys? Zelda DX was one of these and it clearly displays more than 4 colours which is what the GB was capable of?
