Main executable

Depending of which software is used the name of main executable may change since it's not stored in the GCM file: boot.dol / Start.dol and so on.

The page DOL (Gotcha Force) group ongoing researches, technical details and characteristics of the mains Gotcha Force dols.

The main executable embeds MetroTRK, a Target Resident Kernel for embedded systems allowing to remotely debug the game.

We found differents staticly linked libraries in it and in particular HSD engine (HAL Sysdolphin engine). Source files haven't been leaked on the internet but we can find an awesome work realized by "Super Smash Bros. Melee" GameCube community on which we can refer:

-Global description of HSD elements

-Reverse engineering of assemblies rewritten in C

Beta version

The beta version of the game contains differences from the final releases. The 3D map is isometric with 3D elements in it and Borgs descriptions were contained in the screen with two sections: one for characteristics and the other one for the Borg story.
