Translation project help? (Kisaragi Gold★Star)

I'm new to this forum, so I'll try to cover the situation as much as I can.

I'm trying to translate a visual novel called Kisaragi Gold★Star, from Saga Planets. Since I had no previous information about extracting and repackaging data from VNs to translate the scripts, I ran over most of the internet the past few days to search for software who can help me with that.

Thing is, using the most popular programs I discovered (Crass, BGITools, animED and ExtractData), none seems to work fully with this game. Crass only captures images from the game, but neither their music, sfx or script, BGITools I don't even know how to use it, animED doesn't run on my windows 7 and ExtractData was, by far, the one I made most progress, allowing me to extract images, sfx, voice overs and movies, but it doesn't extract the scripts, nor let me repackage the files to their original state... >_>

I even tried to do the same with another VN I have installed, H2O: Footprints in the Sand, and I could even extract and modify their scripts, but again, I couldn't re-compile everything back to the game's original files. So I'm pretty much stuck now.

Can someone help me by giving me a hint about where to start looking for solutions or new programs to help me? I'm really clueless about where to go now...


P.S: Sorry if my english isn't totally right or confusing..I'm actually portuguese xP
