Working on Chu Chu Rocket NES
I am working on a Chu Chu Rocket 'port' for the NES.
Here is a mock-up screenshot showing what it might look like:
Right now, I have the CHR file containing all the possibilities for mice movement finished, it adds up to 100k.

Here come the fortune cookies! Here come the fortune cookies! They're wearing paper hats!
Got the MMC3 interrupts in now, so it is bankswitching every 8 lines now. Wish there was a better way to handle them though, right now I need to burn 165 PPU cycles to delay the bankswitching until the end of the scanline. Obviously graphics are still incorrect here, looks like I have some invalid data in my lookup tables.
I expect to be able to blast the playfield nametable from the buffer into PPU memory within 2 vblank periods.
It will use bankswitching to animate the mice moving to the next square, for all possibilities of mice travelling in all directions. Of course, the walls stop certain possibilities. Arrows and rockets will be sprites.
Should be silky smooth at 60FPS once it's working.

IT'S ALIIIIIIIVE!!!
Blue stuff at the bottom is from turning off the screen early. My nametable updates were 3 scanlines too long.
Edit: replaced image with one including all frames of animation. The old image still available, but it's missing half of the animation frames. You probably can't tell the difference.
