Hi. As a followup to the NES version of Dr. Garfield, I did a quick graphics hack for the Game Boy version of Dr. Mario, also for Game Boy Color.http://www.romhacking.net/hacks/5542/
This is based off of the Dr. Mario DX Game Boy hack by marc_max and Da_GPer, seen here:https://www.romhacking.net/hacks/5281/
This hack added color to Dr. Mario (making it a Game Boy Color game) and also created more NES-like graphics for the viruses.
I've worked on a few NES hacks and gotten familiar with that format. This is my first time attempting Game Boy and Game Boy Color.
I'm using Visual Boy Advance for an emulator, which can look at and export palettes. Not as good as Mesen for NES, but all right.
I don't know much about Game Boy Color palettes, how to generate them, and how to change them. Google searching hasn't been helpful on this topic.
The Dr. Mario DX game cycles through a few different palettes on the title screen and during gameplay. Some work better than others. I need a palette that's basically one color to work with my greyscale title graphics (or I'll have to simplify them).
Since I haven't changed Mario/Garfield's palette, he's a bit pink right now instead of orange.
There is a Mario happy "winning" sprite, I'm not sure where that shows up in gameplay.
I also don't know how to access 2 player mode for testing.
On an unrelated NES note, I am trying to learn how to enable custom music and custom backgrounds in Mesen HDPacks. There's a lot of discussion about this but not much good info, probably because it differs for each game and isn't done automatically by Mesen or related tools.
