"Dr. Mario" for the GameBoy gets a colour remaster romhack by Marc Robledo featuring new playable characters
"Dr. Mario DX" is a romhack originally released on July, 2020, which revamps the GameBoy's original classic with fully coloured graphics akin to a GameBoy Color title, as well as adding new and modified sprites to closely resemble the NES version of the game but with the better colour palette of the GameBoy Color. However, as of November 7th, 2023, Marc has released a new update to the romhack that adds new content, implementing a number of Quality of Life changes into the game's original code, and not only that, but he has added 3 new additional playable characters to the title, with the full cast being Dr. Mario, Dr. Luigi, Dr. Wario and Dr. Daisy to choose from!
You can download the patch for Dr. Mario DX from Romhacking.net's webpage for the hack.
As usual with romhacks, you're required to bring your own ROM of Dr. Mario (Rev 1 / Rev A) for the original GameBoy to be able to patch and play the romhack. Enjoy this beloved classic in its most definitive iteration yet, courtesy of the expertise of Marc Robledo!
