While "Trashman Emerald" might sound like a joke or a poor-quality version of the game, it is actually the most respected and widely used version of Pokémon Emerald
Use an isolated emulator (like mGBA with save states disabled for the "pure" experience). Do not use real hardware unless you know how to reflash a GBA cart. The ROM has been known to corrupt SD cards on certain flashcarts (EZ Flash Omega users report strange "1986" folders appearing on their storage).
If the file size is standard for a GBA game (~16MB to 32MB), this is likely a legitimate copy of Pokémon Emerald that has been modified to run on flashcarts or emulators of the era.
You will likely find the ROM on Internet Archive or specific "Fangame" subreddits under the search term trashman_emerald_final_v2.gba . The file size is usually not 16MB (the standard Emerald size), but 17.2MB—an impossible size for a GBA ROM, suggesting header padding or steganography.
