what are GS roms i N64 ?

i recently downloaded my first N64 rom - [N64] Zelda Ocrania of time from romu and extracted it ,
now it shows many roms and i dont know which one to play with , :-\

Spoiler

and what are the GS roms , and do we need all these roms or can i delete it ?

That's all the different dumps of it. SNES games are like that too.Personally, I usually go with the any of the ones that has the [!] in the name since that's a verified good dump.

so what are the GS roms , and can i just keep one rom and delete all others ?

You mean "GC" not "GS"...I think (and I'm not saying I'm 100% sure) those are the GameCube ports. ???

i think it's a backward port, some one added the master quest designs to the original OOT, there are also hacks that make TLOZ MP.
