Water, Water Everywhere II

What water bug of Sonic 2? o.o?

(Sorry, just curious ^^; )

 

The water has a different palette, and the game tells the Genesis to switch palettes when it gets to the y position of the water level. That's two palette switches. In 2-player mode, it would have to switch it 4 times, and since it can't do that, it glitches.

 

I like the sound of Sonic 2 with water in each level, could be fun! :D But I think you'll have to forget the idea of 2 player water zones because if the bug could be fixed, Sonic Team surely would have fixed it. Good luck on your hack

 

The 2 player split screen uses the hblank interrupt to draw two screens. The water effect uses hblank too for switching the palette. Both are using the same technique, and since copying 4 palettes at one vblank is impossible while making the split screen hack, there will be no way for you to fix anything that can't be fixed.

 

...Unless you make the water completely transparent in the 2 player mode, I guess.
