That article about how Pitfall creates its levels based on bit flags is a pretty good reference.

Yeah, or River Raid. But it depends how much different and how particular each level needs to be.

It's my first proper attempt at a 2600 game in assembler. I like challenges and wanted to cram it into a 4K cart and use the stock 128 bytes of RAM. Already had to make some compromises, such as reducing the size of the play area on screen so I can generate the map in just 80 bytes. Full width would have taken too much RAM space. I'm basically discarding the two four-bit wide playfield areas. I'll probably fill the sides with something else.
