Happy New Year everyone.

It's been a lot longer than I expected since posting a video. I've made quite a bit of progress with Super Mario Bros. At this point all the stages are implemented, although there are still many bugs present. I figured I would show some gameplay, and skip through a few stages. This is being played on JZIntv, and I have to say, playing on the real console is much easier than with using a keyboard.

Mario is now built with three sprites instead of two. Multiplexing is still present for platforms, but there really is not much I can do about that. I've incorporated certain animations into the main game code, such as warp pipes and losing a life. All the stages are incorporated, as well as the three warp zones, and I believe all bonus areas. I've added ECS support for playing sound effects on a separate channel from music, but on normal Intellivision consoles, music still plays in three channels.
Right now the game weighs in at 60KB, a bit more than the original NES game, and the framerate has some dips under 60fps, but I've been still trying to keep things as efficient as possible.
