Rockman 4 Minus Infinity repro guide
The past few years I’ve picked up the hobby of repairing old game consoles, modding them for things like region-free gameplay or RGB output options for the best possible video quality.
One of the things I heard about along the way was a romhack called Rockman 4 Minus Infinity, an amazing hack that redoes the entirety of Rockman 4/Mega Man 4. Most people will probably play this on an emulator because the de facto flash cart, the Everdrive N8, doesn’t support ROM files of this size. The creator has said though he plans to release a new version of the N8 that supports larger games like this.
So, enter the 8-bitter from Voultar. Assuming you have experience with a soldering iron, it’s an easy solution to use to apply translation patches and romhacks to real NES and Famicom cartridges.
But I specifically wanted to make my own copy of R4MI. The only problem is most of the information online is using old methods of wiring messes before a solution like this existed. Not that they’re bad, they just haven’t been updated for modern methods.
And while Voultar’s video covers just about everything you need, he didn’t go over the process of replacing CHR ROM with CHR RAM.
So I spent several hours hitting various forums and sites to gather information on how to make my own. This guide serves as a way to demonstrate a fairly modern way (though there are probably a few things that could be cleaned up) to do this in 2019.
