Wow, this was unexpected, finding a topic about my Atari 2600 demo on a plus4 site!
Thanks all for your kind words, much appreciated.
Regarding ROM size, the 2600 can address 4kb, but this demo actually uses bankswitching, so the cartridge is a whopping 16kb. It might seem like cheating, but when you only have 128 bytes RAM, you can't really calculate anything in RAM and have to rely on tables for most stuff.
It's really crazy working with that little RAM, you really have to watch things like doing a JSR and pushing data to the stack, since the stack ofcourse is also living in those 128 bytes, if you don't keep a careful eye on it, you end up overwriting some important data. 
Regarding my Plus4 demo, yeah, I thought that would have been released years ago, unfortunately the artist I was working with seems to have lost interest in the project (and perhaps the scene entirely) so for now it's on hold indefinitely.
Also, with demos like Metamerism really rising the bar sky high, it kind of have lost any impact it would have had.
I still hope to finish it some day though!
