I am looking for a couple superstar mods that I used to have, one where you could visit studio town an unlimited amount of times, and where you always succeed the sequences, they were from parsimonious sims, which unfortunately no longer has them.

I have a Simsky mod that says unlimited studio town visits:
https://simfileshare.net/filedetails/2799257/
There's another version of it in the Sims 1 CC collection, and some files by Parsimonious too. Maybe you could take a look at those?
https://simfileshare.net/folder/144507/

If the files by Parsimonious at SimFileShare don't have what you need, Hedda at Some Sim Things has a hacked fashion runway and a hacked music video set that give you THREE chances to get it right, instead of the two chances that Maxis gives you.

It's not the same as getting it right with no effort, but it IS much easier than when you only have two chances. You can find those objects at http://www.somesimthings.com/Job/01Job.htm. Hedda also has a lot of other great stuff at her site, so I recommend looking around while you're there.

Also, if you'd like not to have to make friends with snobby celebrities, I have a No Friends Needed for Fame Career mod.

Edited to add: I've been to the Parsimonious website, and they still have a bunch of Studio Town objects. Those objects aren't described, so I don't know if they do what you want, but you could have a look: http://www.parsimonious.org/furniture1/pages/studio_page1.

Thank you so much!

Also turns out I have the mod where you never fail the options, but it turns out it is only for the catwalk.

Thank you!
