Start by having Tshu host your web page. Assemble a group of people who post bimonthly updates. Disregard project and hope another group picks it up. In three or four years, maybe there will be an official developers release.
Unfortunately, there's very, very little (if any) chance of anyone being able to publish this outside of Japan, due to the same sort of licensing issues Jump Super/Ultimate Stars has (If not worse).
Sadly that's true...
I love that game too... I've had a bit of experience text-parsing in the past, so I'll help you with what little I can if you want. If not, will you at least post the patch here when it's done? Maybe some other way to contact me?
Oh, and where'd you find the GaoGaiGar sprite for your avatar? I love it...
