Editing Kid Chameleon Levels

I always loved the game "Kid Chameleon" on the Sega Genesis growing up. It was always very addicting. Kid Chameleon was a unique game in that you could get helmets that transformed you into different beings. It was also unique in that it was an extremely long game -- over 100 levels! Clearly that was a big deal.

Recently I rediscovered this game, and I began wondering what it would be like to modify the game's levels and create my own levels. Since I'm out of school and have some free time, I decided I wanted to hack Kid Chameleon and see about doing this. After several days, I created a huge collection of notes. I also wrote a program that decompresses and extracts tile layout data from the Kid Chameleon ROM itself. I have some screenshots available:

1 - Displaying basic info grabbed straight from the ROM.
2 - Debugging info showing the decompression statistics being displayed.

Now I just have to write code to compressed the data again and put it back into the ROM. Once this is complete, a level editor can be created.

Hey Sax, wouldn't the compression be just doing the same thing backwards?
If it isn't, try looking at other compression techniques. Maybe making a few changes might work?

Sadly, it doesn't work like that. You have to do things completely differently when you go to reverse the process. An example why... let's say we have 2+2. Well when you do that, you get 4. Now we have 4, we want to take it back to the way it was... and that could be 4+0, 3+1, 2+2, 1+3, or 0+4. How do we know which one it is? That's why you have to write entirely new code to reverse it, because you can't do time travel with these types of things sadly =(
