I came across this thread after looking for a possible translation of the game in question, and I got an idea.
What if we create a bounty for a fully playable, English version of the game? Like a pool, that a bunch of forum members, and Dreamcast advocates pitch into?
And the first person/team to present, and give the moderators a fully translated version of this game gets the pool, and gets it/splits it among themselves as the team sees fit. Then the Moderators upload the translation patch to whatever website/s they see fit. I'd put 50 bucks down as an initial show of faith, and then 100 more when progress starts picking up as more motivation. And then keep adding every so often until the final product is turned in.
I really think that this may motivate some people to put forth the time and effort. Especially if more than just myself contribute to the pool (I'm sure more would).
As someone who has no knowledge of the Japanese language, and next to no programming knowledge, I'm just doing what any American with a desire would do. Throw money at it, and it hope it happens
All joking aside, I'm curious if this is a plausible idea.
Anyway, just a thought.
