Step 6Bonus Round - Difficulty: Medium
Since the Dreamcast doesn't have a Select button, we have one button that is completely unused. This and the next Bonus Rounds show you two ways to make the Select button usefull.
The first is using a memory card. Both Sega and Pelican made 4 page memory cards. Each has a small button on it to toggle between pages. There are some made that use a sliding switch to change banks; these will not work for these instructions. Only use a memory card with a button. I have used these directions on both Pelican memory cards, and the Sega memory card shown here.
Using a small screwdriver, open up the memory card to get a good peek at the board inside. You will see a small tactile switch, the one used to change banks on the card. Tactile switches work exactly like the microswitches in our arcade buttons; they connect two lines when pressed. In both of the four page VMU's I've worked on, they both work the same. When pressed, it will connect a line to Ground, exactly like what our Select button does. If we connect Select to whatever this other line is, we'll be able to change the VMU banks just by pressing the otherwise useless Select button.
Use your multimeter to figure out which line on the switch is Ground, and which is not. Connect the Select line from the ribbon cable to the line that is not, and you're done.
