great abandonware for your classic PC

Sure, and more than that, post the new beside the changes, with details of lessons learned. As Jim Leonard said, us developers are more than happy to talk about the design challenges and how we solved them. I had many cool tricks to do real time on the PC, and could write a chapter on it. Most of the code we all write are what I call 'tiny circuits', little nuggets that perform some cool logic thing. One tiny module hooks to another and performs something all together different and cool. In my case, I would be glad to show the code, and talk about it for: Calculating the acceleration, and accumulating the velocity based on the slope of track segments (Euler integration) Determining the camera view matrix from the 3d model as you ride the coaster (some smart guys from the NASA dynamics group gave me the shuttle fortran for quaternion to 3d rotation matrix) circular list of EMM pointers, of the next block to load, the next block to play, based on the PC timer I had limited space, 13 disks, so I looped the audio, for the coaster chain, the screams and coaster sound, picking up the appropriate track segment to associate the sound samples. My intro to each coaster, was a cad animation of the ride geometry constructing, I used a file of Tek 1410 vectors and a simple parser to read and do the cad drawing, rather than have the model in memory, and a 3d cad engine, everything was pre-generated to make it small and play back fast.
