Hi, all. As there are still a couple things I want to add and thus it's only a beta right now and can't be posted on RH.net yet, I wanted to let everybody know about Metroid II EJRTQ Colorization, which converts Metroid II: Return of Samus to full color. This mod combines the art of the beautiful but buggy EJRT colorization 1.2 with entirely rewritten code, fixing bugs and crashes, allowing it to run on most emulators, and adding additional graphical improvements.
The beta is fully playable and the only changes planned before full release are graphical and a suite of changes to make it more useful as a base for other mods (in particular allowing larger, more complex mods with more graphics, maps and scripts). It is known to have been fully completed on BGB, and partially completed (with no known gameplay-affecting bugs) on mGBA, Higan, Game Boy Player, and PocketSprite. It should work on just about any emulator, but is known to not work properly with Game Boy Online.v1.3 Release Candidate
