Do I need the original game files to run Pokémon Emerald Decompilation?

Yes. The project does not include the original game's assets, so you need your own copy.

Pokémon Emerald Decompilation

DecompilationHalted

A disassembly of the Japanese version of Pokémon Emerald. It builds one ROM, pokeemerald_jp.gba, identified by a SHA-1 hash.

You must have a Japanese Emerald ROM named baserom_jp.gba in the project root. Setup instructions are in a separate install guide in the repository.

Original game files required. The project ships code only; you provide your own copy of the game (Game Boy Advance version).

The team can be found on Discord and IRC, and the README links related Pokémon disassembly and decompilation projects.
