Talon112: Well, I have DOSbox running, it's running the game... mostly, but there's no sound, and it's just crashed when I tried to go to Achilles' surface... any suggestions?
I'm pretty sure I was able to run the game in DOSBox without any problems, it was a while ago though. On DOSBox's compatibility page IG is listed as "runnable", people are complaining about crashes, no sound, just like you said. It did have "supported" status on version 0.63. Your best bet would be to try an old DOSBox version, see if it works there. You should also patch the game, the latest version available is 1.3, just google and download it.
I might try installing it on the weekend to see if there are any problems here, I'll keep you posted. I won't promise anything though as I have a noughty one-year-old running around me all the time. :)
