Thanks, though the reason why some people do this kind of thing, myself included, is mainly for the challenge, not the profit. I also don't post everything I'm working on online either, so I have a bit more than a lot of what's needed to make up some pretty amazing boards.
The 2 people that did the CGnome are already working on the Mark-II for repaving that remap road also, 8 lanes both ways, instead of a dirt road like last time.
Board costs like that are only feasible if you have hundreds made up at a time, otherwise you're looking at a good bit more than that per board, plus components and labor spent making them or having them made. Just the wired 360 controller alone is around $30 so you can get the 2 ICs from it you need, then waste the rest. There's no way you're going to make a remap chip, board and the rest of the components for $20, plus have to swap the parts from the CL over to it, unless you already own the machines that can do that type of work and have money to burn on top of it. It's part of the reason the CGn was so expensive, as there's only a handful of them around and that thing was a witch to install. The project was also a money pit, but we didn't make it for selling, it was made for the sake of doing it. I personally wouldn't want to do another one of those things the way it was, and the new MII project idea takes all of the good from it and tosses the bad, so we'll see how it all goes sooner or later.
Your idea would also make it a remappable wired controller, which wouldn't fly in a lot of people's book as they have already 'cut the cord' and wouldn't like going back, even for that feature, and having to solder a 56 pin QFN correctly for someone that would like it, that's more of a challenge than doing the rest of the components, plus takes the right tool for that job.
I'm not shooting down your idea or anything, like to hear all kinds of them, good, bad, simple or insane, cause just about everything has something in it that can be used some place or another, and you're not too far off the mark with your idea.
The 36X board I have partially wired up right now is for an N128 controller project I'm working on, mainly just to see if I can do it, then once it's completed it'll be on it's own board to wire up to the 36X, or outright on it's own 360 style board.
I've also been kicking around a DuXe board as well.TOPBOTTOM
