Because yeah, I can't help: the SuperNES draws me like a magnet. No matter how many times I refrain myself from looking deeper into it, I keep wondering how school rush would feel on the 16-bit queen.

But there is no easy answer. The SNES means only 128 colours for all 3 tiled layers. It means that either the ink or the owl must be patched to work with only 4 colours per tile. And it most likely mean that the twin playground layers of School Rush levels must be merged into a single one, with sprites automatically used where Bilou must enter objects like big binders.

But even with all those limitations, I feel like it would be the only mass-marketed 16-bit  that could host ports of the game. Both Mega-Drive and Amiga lack colours , and I don't feel like asking my bro to give Sega FM chip a try, even though 68000 assembly has more hex appeal than SNES 6502+ instruction set.
I tried other approaches, like using a row of sprites for the owl statue if the ink approaches enough, since there isn't enough sprite resources to implement ink waves as sprites as on the DS (more on that in a later post). But I had to come to the conclusion that merging the two layers into one is the only practical thing to do. So the next question is: how much overlap between layers is there in the levels of School Rush"
 
I have fairly simple tilesets in School Rush, and used overlap to make object-bridging tiles. Merging means that these tiles now need new slots in the tileset. ...
