Old, constrained 8-bit games platforms are full of fun tricks, though most of them are not really applicable to modern x86 assembler. There are commented Atari 2600 disassemblies available. My favorite to just read top to bottom is Pitfall. Relatedly, you can find "demo scene" content that also really pushes the limits of these machines, though most of these tricks are more related to bending/pushing the antique video hardware than slick assembly techniques per-se.
