I don't think he's done anything to advance portablizing. I may be missing something here, but all I've known is that he makes proprietary stuff, and the only time I've really spoken with him, he wouldn't help me. I believe what he'd said was he didn't want his info getting out because then anyone could replicate it. What that told me is that his priorities are keeping what he has to himself, to either maintain a steady profit or monopoly. I could be wrong, so feel free to present any information I may be missing, but I did not get the community-spirit vibe that I've come to adore about other people I've worked with.
As far as what he charges, us poor people consider it a lot. We are natural dumpster divers, and most of us are still in school and still have to squeeze pennies. For making commissions, sure, because then we've got the money to spend. But the majority of portablizers start with whatever they have in their pocket and whatever they can get their hands on, and they generally have to pick their battles financially.
For example; let's take a practical look at the N64 chip breakout board. I'm told it's ~$50. From the pictures I've seen, the breakout points don't look to be much bigger than the actual IC points, and it doesn't appear to have any joystick conversion method. Either way, it's an impractical product, because the CNT-NUS does not require any supporting components aside from the crystal and 2 supporting resistors, and can be cut the size of the chip, with the pins/traces wired to directly. And it's been verified to work 100% with the transfer pack, as well as the basic joystick conversion chips. This information has been publicly available since at least 2009. So in this case, the component cost is, or rather should be, only be the cost of the board. The official N64 board is also single layer, so the majority of R&D is transferring over the preexisting design and making some changes. I'm not sure how much research went into it considering the amount of unnecessary components that are retained, likely for no sake other than posterity.
On the joystick conversion point, that has developed a lot over the last few years, in both circuit size as well as the addition of proper software deadzones to compensate for the 3DS ghosting. But the component cost has remained low, to where anyone can do it for as low as $10 (and in most cases, lower.) So we're talking about $10 + original N64 controller cost, which has to be factored in regardless for a donor CNT-NUS chip. And that's a one time expenditure, you'll already have a programmer for any future endeavors.
I've personally never been able to justify the price when I can do the same thing better for free and teach other people at the same time, so I cannot personally vouch for or against the quality. But if it quacks like a duck, and a lot of people agree it's a duck, my general thesis would entertain the idea that it is in some form, classified as fowl.
Beyond that, I've had multiple reports from end users who are dissatisfied with the quality of the product received. Just today I was shown an previously unopened product from him that still had
very noticeable amounts of
flux on the board, and upon inspection revealed that it had
a lot of leftover
solder balls. Potential problems in the right circumstances, and not aesthetically pleasing for sure, especially against the white PCB. Additionally, the soldering was determined to most likely be done by hot-air, which is a rookie technique for production. This can become problematic for the end user for several reasons, but I digress.
Additionally, with proper technique, swapping over a chip and dropping supporting components should in no cases ever take 50+ hours. I don't know how much product he is moving, but as someone who's worked with professionals, who flux, clean, and meticulously align and solder much more demanding circuits than any controllers we've encountered, I can safely say that that is absurd. Whatever is taking so long may be part of the questionable quality I've heard about.
My final verdict is that I don't have all the facts. If he's helped you develop your skillset and if he's a good friend to you, then I've got no beef with him. My 10 years of experience have taught me that there's no value in worrying about who people associate with, and that holding any negative opinions serves no value. These are just my thoughts based on what I've been privy to over the course of the last few months. I'd say if anything, don't try to pass anything off as top notch until you've seen top notch.
So: there are a few things that everyone else needs to take away from this. The first is that you can charge whatever you want for your product, because it's your product. No matter how original or derivative, no matter how solid or flimsy it might be, it's yours to sell for whatever you'd like. The second point is that once your work is public, it is free to be scrutinized by whomever decides to have an opinion. If Noah and a large amount of other people are posting their thoughts about it, even if they're negative, they're worth considering at least once. And finally, in all things: Let the buyer beware, and don't forget the timeless adage of "stupid pays more."
Either way, the truth will always become clear. If his products are hot garbage, people will stop buying them. If they are expensive, people will buy the newer, cheaper solutions. If they are fine, then there's nothing to worry about, and the work will speak for itself.
