Is uploading rom hacks (such as acnl texture hacked isabelle) illegal?

I was wondering if I could post a texture hacked isabelle from acnl that I made? or if it’s illegal?

In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.

Yes, custom textures are fine. As long it’s just a .png or .jpg file that you can use with Citra’s “Use Custom Textures” setting.

Oh, so not the ones you can import to the .bcres/bcmdl file?

It might be fine if it falls under mods category.

Ok, thanks for answering my questions!
