Sorry for not replying earlier, legowar... I was in the middle of a ton of homework and exams at college, and it wasn't until now that I got a little breath of liberty :xp:
The info that I provided you actually came from IMDb. I don't know where you can get more data from that game in that matter...
BTW, the other day I watched the FT2 trailer (dated 2002, I think) in YouTube, and Ben's voice was already someone different to Roy Conrad. He died earlier that year, and was quite a shock to all the FT community... Well, actually it was worse when LucasArts cancelled FT2...
Here's a picture of Roy Conrad:
