To some extent, the ultimate achievement of a TAS is to achieve <arbitrary code execution> (ACE) on a game, although this has been becoming rarer and rarer in newer consoles. The <Nintendo 64> is the current interesting ACE discovery frontier as of 2020.
Post ACE, you then get into more subtle categories which tend to be more geometric clipping through wall glitches, but those can still be fun.
The most beautiful TAS content ever made are:
* <Super Mario 64>
* <Super Mario 64 A press challenge>
* 1-key any percent run:

* https://www.youtube.com/watch?v=HxFh1CJOrTU Seth Bling does the credit warp manually in about 3 minutes, 2015. Later reduced to less than 1 minute: https://www.youtube.com/watch?v=Jf9i7MjViCE
* https://www.youtube.com/watch?v=voL3e0iqugo ACE was initially not forbidden in 11 exit rules, so Seth made an in-game manual ACE that programs an in-game accessible "exit stage now" functionality!!! This was later forbidden of course, but it was fun while it lasted.
* then he injected a Flappy Bird clone manually!!! https://www.youtube.com/watch?v=hB6eY73sLV0, 2016
* <Ocarina of Time>
* 2020 ACE via https://cwe.mitre.org/data/definitions/416.html[use after free] including a non-TAS credit warp faster than the 2016 wrong glitch: https://www.polygon.com/2020/1/24/21080568/zelda-ocarina-of-time-arwing-spawn-video-speedrun-credits-ace-cheat-code ACE later reproduced in Majora's Mask, which has a similar <game engine>.

It is also amusing to see http://tasvideos.org/ConsoleVerificationGuide.html[console verification] of emulations, e.g.: <video Super Mario 64 '120 Stars' in 1:20:41.52 Console Verified by Soul Umbreon (2012)>.
