what is ssx3-gc-add-4th-grab fr?

This project is a small modification for the GameCube version of the racing game SSX 3, created by a modder going by Some in July 2026. Its purpose is to restore eight grab trick combinations and a fourth grinding trick that exist in the game's disc data but were switched off in the GameCube release, apparently because the GameCube controller has three shoulder buttons compared to four on the PlayStation 2 controller that the tricks were originally designed around. All of the animations, trick names, and scoring for these moves already exist on the GameCube disc, the mod does not add any new content or patch the game's executable. Instead, it changes 38 lines across two small text configuration files that map controller inputs to trick numbers, rebinding the previously disabled tricks so that holding the X button, alone or together with the shoulder buttons, now triggers them. The existing default combos are left working exactly as before. To use the mod, you need the Dolphin GameCube emulator and your own legally obtained disc image of SSX 3 for the USA region. The included instructions walk through extracting the disc image into a folder using Dolphin's built in tool, then copying the mod's two configuration files into the extracted files, overwriting the originals. From there, the game is launched directly from the extracted files inside Dolphin. The author notes the mod has been verified working in the Dolphin emulator but has not yet been tested on real GameCube hardware, though it is expected to work there too since it only uses the console's real X button rather than any code injection or cheat codes. The project does not state a software license, and it explicitly says not to redistribute the game's own files, only the small patch itself.
