I don't speak for the mods in any way but as far as I'm aware the current stance is that runs done on the decompilation will not be allowed, primarily due to the decomp (both v5 and v5U versions) not being faithful to the original among other things.
Included in the Plus DLC. While not required for run submissions as submitting just the replay alone is allowed, it's good practice to record your runs as they happen live since sometimes you might either forget to save the replay after a run (speaking from personal experience) or if a run makes use of pause buffering there's no way to tell from the replay alone what strats are being used.
We seem to have a good amount of people interested in doing this. Hiw do we make it a category?
Have enough people run the category. Runs themselves need to be optimized to some extent at least. An unofficial leaderboard can always be made to keep track of them until the category is added to the catex leaderboards.
