Non-Stop Shotgun Mario 64
I took Dorriel's creation, which is the best romhack ever made in my optinion, AND MADE IT EVEN FASTER.
No getting kicked out of the stage when you grab a star. This way you enter a stage once, grab everything you need, and you're good to move on.
I made sure to fix some of the incidental stars that require a certain star select to make a star or character appear. For example, upon entering CCM, both the slide penguin and the snowman's body appear on star 1. There is also a little surprise that I put into WF so reentry for the tower is not necessary!
All credit to Dorrieal, I just added the nonstop features. This is still their hack!
If you find any serious issues, please let me know. There is already a known bug where the game crashes if you grab a star with little penguin in your hand, but that is not crippling enough for me to fix that.
