an interesting thing about SMB(pretty mind blowing for me)

Back in the times when memory was scarce, tricks like that were precious. A university fellow student of mine programmed games for C64 and knew a lot of tricks like that, so when we did together the project for the CG exam, we did a fractal landscape generator and did the clouds mapping differently the same fractal we used to do the mountains... We were working on MS-DOS, so the first 640k were precious, as although 10 times the C64's memory, for a much higher resolution, True Colour, SW only shading geometric transformations and lighting (our code, as we had to show we learned the course main topics) they were still quite scarce. I deeply hate DOS since then, as only thesis works had additional budgets, so we didn't have even a DOS extender and towards the end, adding some features and increasing the resolution, we were forced to remove or simplify some other features due to memory limits and we had also to write a lot of code to move data to and from XMS, so we wasted a lot of time and efforts for things absolutely unrelated to the course and that slowed the program too.
