At the time of writing this post, the below rule is set for running this category:

"Rules:

• Default settings (2 rounds, 99 sec, 4 stars)
• The timer starts when the character is selected and stops when the final blow is delivered to Bison or akuma
• Continues are permitted."

This needs to be reviewed and changed, as there any many issues that will make it near impossible to submit a fair run.

Super Turbo is also a very difficult category to get right because there are drastically different speed differences between every port. In addition to this, a certain US ROM version has the AI bug where it remains at the highest difficulty regardless of the game setting. The Japanese ROM fixes the AI difficulty issue, but this is not available on the original 30th Anniversary Collection release, nor whether it can be confirmed whether it was fixed in a patch due to Digital Eclipse not documenting their patch notes. The 30th Anniversary International Version (released in Japan), has access to both US and JP ROM versions.

To add further complications, the Japanese version have a faster post-match transition as you cannot speed up the win dialog as it being printed on the screen. The dialog characters are displayed at a set speed which cannot be skipped until it is complete (indicated by being able to speed up the scrolling purple background by holding any attack button which speeds up the transition). Because the japanese version has fewer characters to output, the speed advantage is huge. Easy examples to spot are Fei Long and T.Hawk as they have long post-match win quotes.

The US and JP version also has a confusing turbo setting. The US version has Turbo settings 0-3, and the Japanese version has 1-4. This does not imply that the Japanese version has a faster maximum turbo setting, but it is just branded differently (i.e. US Turbo 0 = JP Turbo 1, US Turbo 3 = JP Turbo 4 etc.)

Also, due to the unstable speed nature of Super Turbo on original CPS2, it effectively means that every port runs at a different speed (emulators, OS platform and console ports).

The 30th Anniversary collection needs it's own category as it has already been proven run faster than CPS2 hardware, it must be made clear that people with the International version (JP release) must run on the US ROM to ensure no post-match transition advantage.

The Turbo setting needs clarification, whether the runner has a free choice, and if not, to state the correct number (US Turbo reference).

Also due to the AI glitch and the uncertainty whether Digital Eclipse addressed the AI glitch in the original 30th Anniversary Collection, it may be worth ditching the difficulty sub category altogether and require all runners to play at the hardest difficulty.

Why is this even a category? You have 12 characters as individual categories, and now there's an "Extra Speed" category with no characters associated with it.

Also, it doesn't belong to the Arcade platform, as you don't get the option to change the speed.
