OK, so I bought a used copy of Nightlong, but I've run into a couple of problems. The first problem is a read error on CD#1. The CD actually looks very clean (nearly pristine), so I'm going to try an older CD drive that I have in storage and/or try to clean the CD drive I'm currently using.
But assuming I get past that problem, I still think I'm in trouble. I'm running OS3.9 with 16 MB on my A3000. The game installation is going to require 15 MB free memory for the RAM disk usage, but OS 3.9 uses more than 1 MB (at least my set-up does). Is there some way to conserve/allocate memory in OS 3.9??
