I was doing this challenge for fun but thought it might make sense. A minimal bullet run could be an interesting run idea as not only still use methods from the original any%, but it would also mean that sections that require guns would require a nice amount of precision. Just wanted to know thoughts on it before maybe pitching it to a mod and elaborating more on it.

Can you use 3D All Stars in a 603 for 64 , Galaxy , and Sunshine runs?

If I want to use the built in ps4 streaming/recording , does it matter since it doesn't show the cutscenes

What would be the difference in how you differentiate between the two trading systems. Is there an obvious way to figure out which is which?

It also depends on which type of speed run you want to attempt. The tips for glitches and glitchless are different but both cut down times. There should be available guides for both.
