If it is not version 1.12 or equivalent , it can not be used for the regular any% category. There is a true any% that allows any version, and 209.4% also allows any version.
Am I not right in saying that the ps4 version is in fact 1.12, and the only difference is that you cant access the speedrun timer? Because none of the 1.11 tricks work on ps4 to my knowledge
I'm not sure if it is the same.
The leaderboard is without loads which is required to be submitted due to load time issues between computers. It has the net effect of making things more fair for more people. The speedrun mode also puts something on screen we can use to track possible cheating.
The game is like a few bucks on pc and goes on sale all the time. If you want to run it on PS4 though, then do you! There is still a leaderboard it can be submitted to. There is a whole other category that can be run on PS4 that is only an hour long as well.
