The [[VMU]] for the [[Sega Dreamcast]] can be modified to accept as a power source an alternative to the pair of CR2032 batteries the VMU is designed for such as AA batteries or an AC adapter that supplies 6V of direct current. The new power source can be soldered directly to the VMU, or a common connector can be soldered to the VMU to enable you to detach the new power supply.
Basically all we'll be doing is soldering the positive and negative ends of our new power source to the corresponding terminals of the VMU. Now, there are two ways to go about this: one is invasive and involves drilling and soldering directly to the VMU's board, and the other involves soldering directly to the battery terminals, which doesn't even require you to open the VMU. The former method will result in a better looking VMU, but the latter is easier, less risky, and entirely reversible. This guide will cover the second, easier method.
Tools needed:
*Small phllips head screwdriver
*Soldering iron
*6VDC power source
*Voltmeter (optional but recommended for troubleshooting)
