You can probably make an offline version for yourself. Download the page and JS, edit any references to be local.

Look at the Japanese ones. NESes requiring the bottom dongle mean nobody has bothered any distribution.

If it's not widely known, it could be some small easter eggs that never got popularized. You'd have to disassemble the entire catalog to check.

It's clear you want to play with hw, but from a sw perspective, if you want useful 8x8 attributes and other features, you're picking the wrong console. Target SNES or Genesis instead.

The only way to get decent performance would be running one line at a time, not one tick. Find all possible sync points, such as the zero sprite hit, and if that happened, re-run that cpu line with the info on where it happened.

The different feet are well distinguishable, but the helmets with just a few pixels' difference would not be.

The four CPU dudes look like hard to tell apart when in action, their colors are too close. If it matters that is, the player may not care which cpu killed them
