It's a [hexadecimal](https://en.wikipedia.org/wiki/Hexadecimal) byte from $00 to $FF. +- `hhll` is the RAM address to write to. Note that it's [little-endian](https://en.wikipedia.org/wiki/Endianness) in the code, low byte first. We can reverse-engineer the meaning of particular codes, and discover our own new codes, with the [**symbol files**](https://github.com/pret/pokecrystal/tree/symbols). When we run `make` to build the ROM, along with the .gbc file it creates a .sym file. This file lists all the labels from the source code with their corresponding banks and addresses in the ROM. |
