Sega Dreamcast MODE External Button for Disc Changing
Adding this button to your Dreamcast console with MODE allows you to peform the "Disc Swap" necessary to switch discs in multi-disc games easily by simply pressing in the button.
2 wires plug into pin headers on the MODE. These wires first get routed through the vents on the back of the console, where it is mounted (peel protective film and stick)
See pictures for more details on installation (hover over each picture for descriptions of each)
No longer will you need to remove the top of your console shell just to access the disc swap button on your MODE.
