Cool!
Seeing this prod, I have questions: How does the roto menger cube things work? 🤔
By rendering the frames at build time. :)
Unfortunately, playing back the animation isn't straight forward. There are some limitations in the SMS hardware that makes it a little bit tricky.
The SMS only really supports tiled graphics, with 8x8 pixel 16 color tiles and 768 (32x24) tiles on the screen. With 8k VRAM there is room for 512 unique tiles, but in practice about 448 since some of the VRAM is used by the tilemap. In addition, updating the VRAM is quite slow since the CPU only has unlimited VRAM access during VBLANK. About 53 tiles can be updated during VBLANK with an additional 60 when the display is active.
To play back the full screen animation at 25 fps I had to cheat a bit. Only 192 tiles are used per frame, but fortunately the SMS hardware supports tile mirroring in x, y and both. The menger sponge looks pretty nice with the tile mirroring and by using different tilemaps there is some variation even though the tiles are the same.
In addition, each frame only use 4 colors (2 bpp), so each tile contains the pixels for two consecutive frames. Switching between the two is done by changing the palette.
If my calculations are correct, only 48 tiles (1.5 kB) must be written per video frame (50 hz), which is well within what the SMS can handle. - isokadded on the 2025-01-11 20:50:49

- AI or not, in my opinion, in this intro the tech is the main point and the image is more or less just a prop.
