Myself and spikeman have been tag-teaming the gbcolorizer code and have managed to get colorized gb games running on real hardware:
Here's the patches in their current states.
Metroid 2:

Spikeman is working on fixing that annoying random glitching tile bug. Once that's fixed really these will be running flawlessly. I'm currently getting people to playtest metroid 2 since I don't know the game very well and I figure someone with experience could plow through it much faster than myself.
Hardware testing was done on a couple of gameboy devcarts I built. My mbc 5 devcart supports uv eproms up to 1mbyte and dip flash chips up to 512k. Also my mbc5 cart has the largest size sram and a battery circuit so it can save your game as well.
