SNES Assembly Extractor

This tool converts Mesen emulator txt log traces, into structured asm files.

It handles code repetitions and SPC700 audio code.

This was developed using Mesen, but I don't guarantee if it works for other emulators. Contact me if it does.

It should work for any SNES game.

Important

No rom, game assets, nor extracted code in this repository.

Example result

Using a log named DKC1_USA1_2.txt :

Overview	Bank_00.asm

How to use it ?

Before using it, you will need to get trace logs.

bash run.sh

This will reads all .txt from traces/, delete double code, and generate .asm files in result/{FILE_NAME}.

Note

This process can be long depending on the trace files size.

How to get game code trace ?

1. Launch Trace Logger

On the toolbar at the top, select Trace Logger :

Make sure you got these exact settings for better compatibility :

3. Log to a .txt file

Select Log to file... :

Warning

Trace logging can quickly generate VERY large .txt file, a file from a 20min session can take up to ~60 Go ! Make sure you got large free space.
