I have a pretty good Party Style Any% run. This run is also All Notebooks good run. Can I send this run in two categories?

yes, you can, because I have seen duplicate runs in other games before, because they can be in two categories (I saw that once in SM64 in their category extensions).

You can, as long as both of the runs followed the category rules, which they did. Tuotelly has submitted the same run in 2 categories before.

Sorry for the late reply, but yeah of course.

The only place where this would work is All Notebook and Any%, though. We don't accept double runs of Any% and Secret Ending together because they are technically different endings.

I think im writing this on wrong forum but thanks for information you cant submit se and normal ending. I am trying to do se and this information was helpful if i done se and submitted in any and se.

dont ask me about a sword that a picture

i would think not because your not doing the conditions to the run but if you say so...
