================================================ DR MARIO DX v2.1 by kensuyjin33 & marc_max ================================================ This patch transforms Dr. Mario Game Boy game into a Game Boy Color game. Enjoy the Game Boy classic now in full color with a very cool new feature: character selection! That's it! Dr. Luigi, Dr. Daisy and Dr. Wario join the virus battle!

They are the authors from Dr. Luigi hacks for Game Boy and NES respectively, which were the inspiration to add him in v2.0. We also borrowed temporarily a few graphics from both their hacks during the development, although we ended up doing new graphics from scratch.
