Well, your reply is completly fine and legit, or however I am supposed to say that.
I think you should contact 5438A38A for help in an e-mail, since he doesn't visit the forum anymore for some reason.
At first I wanted to say "I don`t think it is a good idea to spam-annoy the creator himself with ever possible single issue" but then I was like "What happened? I don`t hope somebody here of importance is in bad terms with him".
I worked once quite well with the creator of an other project in the past (nothing related to SMBX, completly different genre and game), until exactly the earlier mentioned situation happened. I don`t want to generalize it, but at some point it looks like some programmers of projects with several fans behind it turn a little bit insane in terms of proud or self-love. Well, actually I experienced this even twice in the past ...
Of course this can happen with a lot more people, outside of games.
Therefore - even if it means I won`t get replies - I don`t want to PM or e-mail him with something like that. A lot of other people might get the same idea and it could annoy the crap out of him. I really hoped there are some other people with some knowledge here. If this is not the case then the whole community can not develop itself, since nobody knows how to realize whatever comes into his mind. "We" can not trust just him to give us the answers we are looking for. So it looks like the knowledge is pretty much only in the mind of the creator himself so far, which is really bad.
But if I am right and something! happened here(?) (which can happen quite fast BTW) - then whatever I would ask him, I would just piss him off. I am very sure about it. I have gained my (sad) experience in these matters.
