Is using a Super NT allowed in all the categories for official speedruns or will I have to use my original hardware? Either is fine, but the Super NT is overall easier for me to use. Thanks!

After a little bit of research, I would say that the NT is okay for speedrunning Barbie Super Model.

For speedrunning in general, my concern would be how it emulates lag, but that's not something that ever comes up in this game, so it should be fine.

Thank you!
