MS43X Custom Firmware

MS43X is a custom firmware that's based on MS430069, but with several new and some extended functions. Summing up it can be seen as the successor of patchlists for 430069 and will include all future feature updates. We decided to go this route because of the raising difficulty of adding new features without butchering existing ones and optimization of execution time.

Overview

All the basics and resources will be explained here. For a more detailed explaination check out the sub views.

Downloads

The main difference to existing firmwares is that we will no longer be publishing patchlists, because that left room for problems and lead to frustrating results in the past when used incorrectly. Every new MS43X firmware release will get new definition files that will come bundled with it.
