What I was doing was just do everything the same way as Tenshots did and it worked. You can do everything the same way I was doing. To be honest, I don't remember much about the original anymore but I can try to reply to questions if you have any.

Also, Bogan has new strats so mine might be irrelevant.

The rule set for the Glitchless category was created long time ago (I wasn't part of the community so I have no idea how/why/when). Disabling sound is not allowed because it causes Dracula cutscene skips which I assume is considered a glitch (I'm pretty much guessing here, as I mentioned I don't know much about how the rule set was created).

Also this is very off the topic.

Launch the game in Windows 98/95 mode compatibility. That reduces 95% of the crashes. To skip the rest (those that happen always when dying after killing bosses) you can just save, hit F2 and reload the save quickly. (EDIT: actually some very rare freezes will still happen.)

@ArtismExpert maybe it's just that people don't know answer to your question?

What you seen at Mother Brain was that glitch. I believe that rules are so specific about it because it's actually pretty easy to trigger that glitch by accident, even in casual gameplay if you can just mash fast. In those 3 specific places mentioned in the rules using it is prohibited because you would need to "go out of your way" to trigger the glitch and keep mashing to keep it up. And that would be pretty obvious that you are doing it to gain advantage from it. (I'm not really sure about what I wrote really, that's just how I was interpreting it).

I believe categories are created when runners that run them request them. If you run a specific category that you would want to be included you would most likely have to ask moderation to include such category in a list.
