Sega Master System power cycle mod

snaker has posted a complete hardware and firmware tutorial in the forums.

This document describes, in full technical detail, the complete process required to make a Sega Master System 2 work reliably with an EverDrive, a Mega Drive controller and the Light Phaser, without manual power cycling, without unreliable soft resets and without electrical side effects. This is not a simple mod, but a tightly coupled hardware and firmware project built on top of SMS++.
