This is a mini-project I made just for fun and for practicing with bitwising and the Rust language. This is a mini-project I made just for fun and for practicing with bitwising and the Rust language.
The code is not the cleanest ever, but I have plans to improve it later (I hope so). The code is not the cleanest ever, but I have plans to improve it later (I hope so).
The 1st generation Pokémon sprites are compressed with a very interesting algorithm very well explained [here](https://youtu.be/aF1Yw_wu2cM) and [here](https://youtu.be/ZI50XUeN6QE) by the Youtube channel [Retro Game Mechanics Explained](https://www.youtube.com/channel/UCwRqWnW5ZkVaP_lZF7caZ-g).

I tried to implement the whole algorithm by myself (by only taking the videos as reference) but I struggled a bit with the delta-coding step, so I took some reference from [this project](https://github.com/xvillaneau/poke-sprite-python/) (Thanks btw!).
