The reason there's no romhacking sub-board on nesdev is because
there's an entire well-established (17 years!) website dedicated to romhacking with their own forum/board/system. In fact, there used to be SEVERAL such sites in the late 90s/early 2000s, but over time things got consolidated because the community often hated having to go to several sites with their own separate boards. How things are now is actually light years better. I've been part of the general romhacking community since it started, and some of the sub-communities, for a while -- not to mention hosting at least 4 separate ones on Parodius,
including that which is now romhacking.net (my post count there is not reflective of how long I've been in the community). New folks who want romhacking-esque things are almost always referred there because that's where people who do that kind of work reside. It's like how you'd come here if you wanted to do NES-related development, not forum.6502.org. As such, I really must stress that adding a romhacking board or sub-board here is not a good idea -- directing people to a dedicated site for the subject is much more effective, no matter if *you*, a single person on planet Earth, don't like that sites' rules.
The reason there is a "gigantic megathread" is because the forum moderators are probably tired of everyone and their dog showing up asking for someone else to do reverse-engineering efforts; the megathread is called
Hack ideas: for those without the skill but with all the ideas due to how prevalent it is for people unfamiliar with reverse-engineering (or even the console/system they want to RE a game on!) to want something done "magically". The difference here is that you're absolutely skilled, considering you've written NES games, but reverse-engineering is a whole other ball game -- and you know that, and you'd rather spend your time/energy elsewhere than learning that art (and that's totally OK!). *They* don't know any of that though!
Romhacking is often a task of passion and desire; the person doing usually has a personal and vested interested in it. For example, some of the most famous romhacks like SD3 took years and were done by a small number of people, all for free, with an immense amount of love and appreciation for the game itself; the same goes even for smaller projects.
Here's an example, where a team last year did a translation of the Famicom release of Rampart, which is something I had been working on for many years by myself (just to get to the point where the translation could even begin), and I commended them for doing it but also felt kinda bummed because it felt like my efforts over the years were for naught. Not their fault, just how it worked out. My point is that this type of effort is usually something driven by personal interest and dedication; you'll need someone who is interested in Soccer to the same degree you are.
RHDN apparently greatly shuns monetary exchange for efforts -- and that's their choice. It's probably similar to how when I ran Parodius, no sites were allowed to have monetary transactions or exchanges happen on them, i.e. no offering money for services, no selling/buying of things, no storefronts, etc., because I put myself at great legal and financial risk doing such. RHers who *do* want money for their work will discuss it once the conversation has begun (ex. "Hi, I'm a NES developer who was interested in hiring someone to tweak an existing commercial game to do something different engine-wise. Would anyone be interested?" {several days go by} "Hey, I'm Bob, I like Soccer too and would be interested in knowing what you're wanting changed. I might be able to do it for a fee?" "Great, let's talk!"). Most of that conversing used to happen on IRC in real-time on #romhack (which varied per network); no idea where people go these days to discuss such things. I will note, however, that there are classic stories in the romhacking community of people being paid to work on a project and then disappearing/bailing once they'd been paid, as well as people who did romhacking/RE work for money but then never got paid (and actually this happened for a was-intended-to-be-a-commercial-game too: Neo Demiforce's
Drymouth for the Gameboy Color. See the DRYMOUTH.TXT that comes with the game to get an idea of what happened (re: Stewart Bell)); these situations could also be why monetary exchange is shunned there.
If you don't like how romhacking.net's board operates, their rules/model, then that's OK. Everyone can have whatever opinion they want. But coming back here and literally whinging for *an entire phpBB thread page* about it, followed by trying to get a sub-board made for something that an entire site is dedicated to, all because you don't like their model of approach and how they operate (esp. for new posters), is not an act I'd expect from an adult. Besides, your bitching isn't even directed at the right people -- nobody here can answer WHY their board operates how it does (rule-wise), and the answers WE give you are never enough; you're always thirsty for more arguing**. Pragmatically stated, why not direct such strong feedback to
the staff that runs the site? The guy who runs it is an established romhacker by the name of Nightcrawler. They also have a
Twitter account, but I think that's used just for general release announcements and not for DMs but I'm unsure. If you want, you can reference this thread (and even my post here -- he knows who I am, I used to host him :-) ) as a kind of "see, this is my frustration vented" reference. Your choice.
I won't be responding past this point for the simple reason that for me, this has taken up enough of my own time/energy. I do hope that you're able to find someone who can do what you want with Soccer, or if you can't, that maybe if you feel up to it, you take the first plunge of reverse-engineering a commercial game entirely without source.
** -- Folks who have known me for a long time, especially on IRC, will laugh heartily because they're thinking "wow, and that's coming from koitsu, King Bitchfest himself! Pot kettle black!"
