Lucky1s color work is fantastic! I've been spending quite a bit of time getting all of my DMD displays optimized with your EXTDMD and palletes and wanted to share/contribute. I took his original pack and then organized them by color and found the best stern rom replacements for different color themes and added a bunch of new games.
There are about 296 folders in this archive
For any replacements, I copied the original pin2dmd in the rom folder as a backup.
The stern DMDs, even the not color patched ones look much better I think with these. This set does assume you patched the ones with color rom versions as well.
Be sure to backup your altcolor directory to revert any of your customizations.
