Thanks! I'll try that. I'm concerned, though, because the article says it enables one to play BG and the two sequels as one continuous game--and I'm not about to replay BG1 just to get to BG2. It took forever for me to finish BG1 (and I have no saved games); I'm not going through that again anytime soon--probably not in this lifetime.
Honestly, I don't recall everything that I did from that link--it was quite some time ago, and once I was sure I had everything up and running, I continued with other projects before returning to BG2. I can assure you, though, that I didn't do everything there--and that I, too, didn't restart BG1 and play the whole thing as just one game.
*If* I remember correctly, I just did the fixpack and then the widescreen mod. The result was satisfactory, although maybe you'd want to add the mod that increases text size or other mods to fine-tune your experience.
Whatever the case, the resources referenced in that link were enough to get things up and running for me.
