-First of all, I wanna note that this config pack isn't as great. I wouldn't allow power-ups at this time. I don't know about the rest of them but if you have a Fire flower and shoot fire balls You will turn invisible. You can play Normally still but then it will crash real soon.
-Secondly, all codes are from the 38A one and I changed it up, that means that some code aren't tested yet. I mean not like this isn't tested yet I tested this. But I tested this with Vanilla SMBX episodes. That means that the rest of the SMBX episodes that are different from Vanilla is not yet tested. (You can report anything like that here.)
-Third, The editor is in beta. Not only that its beta but you sadly can't use it. If you want to make a level use 38A 1.4.4. Again, because the code is from 38A. Why not 1.4.5? Like, you can use it but its very unknown what will happen.
-A fact I know is that SMBX version episodes that are working perfectly with this are 38A and 1.3.0.1 which means again the rest is unknown
Updates will some sooner. (If I can get bug reports)
Changelog is right here
