PhobGCC v2.0.5 Gamecube Controller Motherboard Kit

The PhobGCC v2.0.5 is an open-source replacement motherboard for the GameCube controller, specifically developed for competitive gaming. The hall-effect sensors operate without contact using magnets and therefore do not develop drift, even after months of intense training. The integrated snapback mod compensates for the stick's overswing when springing back, preventing unwanted inputs. Phobvision allows configuration directly on the TV via an integrated NTSC composite output.

Note: For installation, the original board must be desoldered, the stick boxes and slide potentiometers transferred, and small magnet holders printed and equipped with magnets that must be procured separately. Shell notches for consistent angles in wavedashes, Firefox angles, and shield drops still need to be physically filed, but can subsequently be freely calibrated with the PhobGCC and are no longer bound to a specific shell.

Features:

• Hall-effect sensors enable drift-free sticks through contactless position sensing with magnets
• Snapback mod prevents unwanted inputs when the stick is springing back
• Notch calibration makes filed shell notches freely configurable and shell-independent
• Digital LR mod allows switching of the triggers to digital mode with definable analog value
• Phobvision offers direct configuration on the TV via integrated NTSC composite output
• Tournament lockout prevents accidental start and taunt inputs in competition

Examples of Use:

• Competitive Super Smash Bros. Melee with precise wavedash and Firefox angles
• Super Smash Bros. Ultimate with digital triggers and snapback-free gameplay
• Long-term training without worry of stick drift or degradation
• Tournament deployment with consistent shield drops and optimized pivots
• Individual controller customization for different characters and playstyles
