The issue is I have a lot of other obligations and there aren't many N64 hackers. This project requires the largest degree of work to make any individual change, so it's the furthest down on the list. It only makes sense: many of the errors being ironed out of this patch are entirely because I was distracted with other projects on the side. It's only when everything else is cleared off the table that I can really dedicate any time to it.
In the meantime I've assisted in or worked solo on dozens of other projects, most of which are finished or nearly-complete as well as behind the scenes work on prototypes and hardware documentation. A lot of consultation work. For the most part it's small jobs that can be finished quickly or really difficult jobs that are holding up other people from finishing what they've started.
If it wasn't just the GC dialog shoehorned into the N64 version I'd feel a lot better about it (and there wouldn't be nearly as much work), but I'm just as hopeful to get it done one day.
Actually, all that other work has revealed just how slapdash the original codework was, and I've really been on the fence about starting over from a completely new codebase. Even the variable width font can be implemented better, or I should say already has been in a different project. The codeword correction error was revealed via work on a different title, and now I have a 100% Nintendo-accurate compressor thanks to all that de/recompression work for the N64SoundTool and Midwaydec.
I don't expect it to get done any time soon (it's at something like #5 on the list right now, though that should soon be #4). It just requires much more dedicated time than anything else I've been suckered into.
