Yay, I finally found some time to work (a bit on this game!
And let me tell you, I didn't do much on the game itself, because I was busy coding my image converter for the game boy.
You see, the game boy uses it's own format when it comes to images. Tiles and tilemap, sure, that was expected. But the "color" information too!
Not unlike some old 8bits (or 16 bits) computers, the GB uses "bitplan" (kind of) to store the color information of the graphics.
Well, it's not really true bitplan, but basically, instead of storing colors with numbers (0=white, 1=llight gray, 2=dark grey and 3=black) one after an other like lot of systems, the GB splits it. You can view it like first, "is it black or white?" and second, "was it pure (white or black) or a grey(light or drak grey)?".
So you have to "knit" the bits of the bytes, and even if it seems funny at first, it gets old really fast.
So, I spend like 1h correcting bugs in code, and 2h coding a python script to convert images XD
Oh well, progress is progress!
