I have a run I did, but i had a music mod, and a Input Display mod that simply shows what buttons I used through out the run, i also did it on single player with sonic and tails, but used tails to fly, would any of these make my run invalid? I read the rules before doing the run, but i didn't think about these things until after the run.

Edit: also the run did end at the wrong time because i hit it when the final "Act Clear" screen popped up instead of on the final hit

There isn't a Sonic and Tails category and if you used Tails to fly in what is normally a Sonic run then it would invalidate your run I'm afraid.

Oh ok, well thank you for letting me know!

Why don't we just make a Sonic & Tails category then?

would "Input.Lua" a wad that simply shows your inputs on screen be against the rules for these speedruns? here's a link to the page so you can look at it if needed: https://mb.srb2.org/showthread.php?t=38691

@Kitoko The same reason there isn't a "insert name of random thing% here" for every suggestion you could fathom, there'd just be too many categories with no runners.

@GunnerRunner as for your question, it doesn't look like it gives any distinct advantages to use or break the game that I can see from looking at it. It will, however, be reviewed if there's some sort of glaring exploit being used with it.
