The NES is Nintendo's first real console that everyone really know about.
Target the PowerPak
Since the PowerPak is the most common flash cart which is available, it should be the target. This way the code can run on native NES systems, otherwise it would not be a novelty.
The PowerPak on the NES has the following space limits:
- 512KiB Program
- 512KiB CHR
- 32KiB Battery RAM
The NES has the following limitations:
- 2KiB RAM
The NES has a very limited means for drawing graphics. When it comes to the background, everything is an 8x8 tile. I would like to have pixel level control and have a framebuffer, so this likely means that there would need to be quite a number of tiles which make much pixels. For all possible pixel combinations I would need 4,096 tile for each unique combination of tiles. However if I instead reduce the resolution by half, they all fit.
