I know speedrunning has many emulators banned for unfair advantages or slow speed, but I was wandering if a normal playthrough such as blind or casual allows emulators?

Can anyone give me a comprehensive list of notable video game developers? All I know is that are too many that have only made one game and others that have made many. I was thinking by revenue or games.

Could someone mind describing exactly what happens with these unfair emulators?

For example, I looked at Spyro The Dragon runs and saw that some EPSXE versions are allowed and others are not. Is this because some emulators give unfair advantages and others don't? Does it have something to do with the speed?

I'm thinking that I may stream games on consoles in the future. Which is best to use?

I can only stream using emulators on my laptop, and I don't have a capture card or capture device. Only console I have are the Playstations and my dad doesn't want me to spend my money on buying this recording stuff or new consoles. Problem with trying to stream or better yet, speedrun, is that I have no surface such as a table to set the laptop on as my dad's computer is on the table and there's not enough space for another table because we have so much stuff in our room (we had to move into my sister's house). On my bed in the only way I can use my laptop, but it places me in an uncomfortable position as I have nothing to set it on but my legs and I can't properly stand it up. This seriously affects my judgement of streaming, especially if I'm trying to speedrun. Any suggestions? I suppose I could try to get some kind of table and see If it fits in a tight corner next to the door.
