@ -34,6 +34,7 @@ This game got some attention on 4chan: [1](https://archive.li/Yzcwt), [2](https:
- Gamebino Meta (80 x 64, 48 MHz ARM, 32 KB RAM, 256 KB flash)
- Ringo/MAKERphone (160 x 128, 160 MHz ARM, 520 KB RAM, 4 MB flash)
- ESPboy (128 x 128, 160 MHz)
- Nibble (128 x 128, 160 MHz)
- unofficial [bare metal Raspberry Pi port](https://github.com/msx80/anarch-baremetalpi) by msx80
- Has **completely NO external dependencies**, not even rendering or IO, that is left to each platform's frontend, but each frontend is very simple. Uses **no dynamic heap allocation** (no malloc).
- Can fit into **less than 256 kb** (including all content, textures etc.).
