I did janatorial work for a development company here locally many years ago and you would not believe the amount of sticky notes that were everywhere. I had coworkers that would just throw them away if they were on the floor.

I got so mad over that.

I picked them up and stuck them to the seat of the chair instead. That way the person working there might see them and be able to put them where they belonged - at the very least, potentially some archaic code/trick might not be lost due to someone throwing it away. I never put them near any other sticky notes in a work station because I understood how that could easily throw off their work.

I can only imagine the number of tricks and code snippets that were lost because they were on sticky notes that fell off and got thrown away.

I know 3DO and Sega Saturn games are horrible to port due to them using square polygons instead of the industry standard of triangle polygons. I talked with many programmers that hated those two systems for that fact. Of course, when they came out, especially 3DO, 3D stuff was still quite new and an industry standard was not really set. They simply picked the wrong horse to bet on.

By the time the Saturn was in development I don't think there was a standard either. We would not see that actually occur till the 3D card wars on PC.

I know a lot of PSOne games were developed outside the standard tool kits that Sony provided which causes trouble porting to other platforms now. Probably because source code is not available anymore or something.

PlayStation games had a lot of that jittery warping going on with the textures. Some were much worse than others but some were almost unplayable without getting a headache.
