Your hack is on the site now.
Yay for the first romhack I was involved with that runs on something besides an arcade board!
Oh that will awesome to see than real system gameboy color system.
We took a quick look at marioland 2 yesterday. It's going to be tricky. We need some free space somewhere in bank 0 to add bankswitching code so we can call colorizer code from empty banks instead of inserting it over existing game code. Marioland 2 has no free space at all in bank 0, meaning we'd have to relocate some of the existing game code
which is anything but easy. It's possible to do, but it's going to take a huge amount of work. We also looked at metroid 2 and metroid 2 has more than enough free space in the beginning of bank 0 to add bankswitching code. Therefore we're next working on colorized metroid 2, and then marioland 2 I assume would come after since that's the only other colorized gb rom I know that was done using gbcolorizer.
What I'd really like is for someone (or group of people) to use gbcolorizer and colorize all of kirby (first kirby) and / or trip world. These games really deserve a colorization.
