There was an effort to organize the files a little bit for presenting in this repository. I hope I have included everything needed for both Glider 4.05 and the Room Editor 1.0.3. The code is in Pascal — THINK Pascal was used to build the original. I’m not sure how someone would open the project files (or for that matter the resource files) these days. Never mind there is also a .o file (SMS.a) representing a statically linked library (from hand-coded 68K assembly) for doing performant 4-channel sound on 68K Macs in the day (this was licensed from Patrick Buckland — I’m sure he won’t mind my preserving it here for posterity, right?). Art files, sound files of unknown format…. What a joy it will be sleuthing through these files…. Enjoy.
