Nintendo Gamecube Games with Debug Symbols

Edit on Github | Updated: 25th April 2020

If you are interested in reverse engineering a Gamecube game, the first step is to find out if the game has its debug symbols available, this makes it much easier to reverse as all the functions will have nice friendly human readable names.

Gamecube game executable can come in a number of different formats, one is the standard .DOL file (short for dolphin) and the other is the ELF which is a standard format for Unix based systems.

If a Gamecube game disc has the elf file available then it is possible that it will have debug information embedded inside it, the easiest way to check is to look at the size or run the strings command on it.

ELF Files

ELF files can contain many debug symbols such as the function, variable and sometimes even file names.

You can normally see the symbols by opening in a dissasembler such as Radare2 or IDA Pro.

ELF Executables with Debug Symbols

The following table lists all the known Gamecube games that contain ELF files with debug symbols embedded inside.

Link Maps (.MAP files)

Many Interactive Demo Discs contain link maps which are files that the linker generates and contains the function names. Also in retail games such as Animal Crossing and Final Fantasy Crystal Chronicals. One good way of finding these is to do a string search of the GCM ISO files for “.text section layout”.

Prototype Games with Debug Symbols

Prototype games are even more likely to contain debug symbols as they are intended for either testing or journalistic usage, thus having the symbols available would help the developers fix bugs before the final retail release. The table below is an incomplete list of prototypes that have debug symbols, if you know any more please let us know!

Game Name Map File Number of Symbols Genre Notes
NFS Underground (Preview 10-09-2003 Console+ 26669 - 010) Speed.elf 9,604 Racing Uses SNSystems Library + Debugger
Resident Evil 4 (Debug Build) Bio4.*.SYM 10,380+ Action Contains SYM files for the main executable & the REL overlay files (some RELs are stored inside DRS containers) - unknown what created the SYM files, but a parser is available.

Pikmin 2

Thanks to Nikki (@NWPlayer123) on Twitter we now know that the pikmin2?P.MAP file in the retail Pikmin 2 release is full of junk data, as Nintendo had a tool to scrub the debug map file but the file entry on the disk still remained.

The good news is that there are 2 Demo Discs of Pikmin that contain a valid Pikmin 2 symbol map, as mentioned in this twitter thread by Nikki:

Nintendo Puzzle Collection

Nintendo Puzzle Collection (Japan) contains an ARM executable for running on the GBA that has developer symbols in it called: ponagb2m_client.elf (Panel de Pon game?).
