Hi. I think it is better to talk about your issue here, rather than on the Talk page of Sonic Mania since it is not related to it. In any case, this syntax I gave you would certainly not work if a similar syntax to it is added on a url (in your case, it is "?diff...."). In order to combine my syntax with the "?diff" one, you have to replace the question mark in the code I gave to "&".

And then it should work.
