Installing PicoBoot

PicoBoot requires soldering directly to the motherboard. Wrong pads or cold joints can permanently damage your console. Unplug it first, take your time, and double-check every connection before powering on.

Installing PicoBoot

PicoBoot turns a cheap Raspberry Pi Pico into a modchip that auto-boots Swiss. The job has two parts: flashing the Pico, then wiring it into the console with roughly five wires.

Flash the Pico
Hold the Pico's BOOTSEL button while plugging it into USB. It mounts as a drive; copy the PicoBoot firmware file onto it. The Pico reboots itself once flashing finishes.
Open the console
Disassemble the GameCube to expose the motherboard. Identify the solder points listed for your board revision.
Solder the wires
Solder the small set of wires from the Pico to the designated pads. Keep joints clean and make sure nothing bridges to neighboring points.
Test
Before fully reassembling, power on with a prepared SD card inserted. Swiss should launch automatically. If it does, close up the console.

From now on, every power-on drops you straight into Swiss with no disc or save needed.
