- The Emerald Source Code Commentary is a book that examines and explains the source code of Pokemon Emerald, based on PRET's decompilation work.
- Pokemon Emerald is an ideal case study for video game implementation due to its GBA platform, modest scope, and C-based code.
- The game's source code is fully available but unauthorized, with Japanese comments and variable names that are hard to decipher.
- PRET's decompiled source code is used for the commentary, as it compiles exactly to the official English Emerald ROM.
- The decompilation is based on the commercial release, lacking debug tooling present in beta builds.
- Emerald has many bugs, and PRET's code base includes optional fixes via #IFDEF blocks.
- The commentary recommends having the PRET Emerald repository open while reading for reference.
