Trying to start SOUND.BAT is impossible in 64-bit systems it seems.
And now I haven't got sound anymore when I start RoA1, although I didn't change any sound setting in the dosbox conf.
I'll try restarting the PC anyway.
Edit: sorry mods, I forgot to check the "question" checkbox :/
Further update: the interface wasn't consistent and so I though there was a compatibility problem, while the problem was that you "can't" click on attributes to roll them, but you have to go through the menu. One question less, at least, so I deleted that part.
