Gumboot
Gumboot is a MINI-based boot menu for the Wii, created by neagix, specifically for use on his wii-linux-ngx project. Techflash ended up making a fork of Gumboot to fix bugs and update it for the modern era. Gumboot was previously the main bootloader used by the Wii-Linux project, though it is now considered legacy, and NPLL should be used instead, as it offers numerous advantages.
