I'm going through my NES rom collection and I see:
Dragon Warrior (U) (PRG0).nes
Dragon Warrior (U) (PRG1).nes
and about 50 other games that also have the (PRG0/1) crap in them but there's no mention of that code on this page:

Sometimes I wish someone would go through all the rom collections and remove all the the duplicates so this didn't have to be so confusing!

Version?
Possibly Revisions?

Oh and what do you think of "rev x"? For the most part I've been going with the highest # revision available but what do I choose between 3 and X?

Oh and what do you think of "rev x"?

Yea, I guess I'm going to have to go with the random pick idea...
I've played like every single multiple rom to see what I could see and I saw nothing different!
Oh well, I'm sure if someone were to come over and play a game they probably wouldn't have the slightest clue that there's multiple roms out there and the one they're playing may not be the same thing as the game they played as a kid. ;)
P.S.
Perhaps I shouldn't have mentioned the "rev x" thing, I just finnished going through the list and the only game that's like that is Barbie. Does that make me gay? :P

No, you're just a barbie girl, in a barbie world... life in plastic, it's fantastic...... :-X :-X

If you take a look at what a NES cart is, you'd see that PRG0, etc represents chunks containing the binary data of the PRG ROM. If there
are more than 1 PRG chips on the PRG bus, use PRG1, PRG2, PRG4, etc.
One PRG chip would have PRG0
Two PRG chips would have PRG1
etc.
Almost all only have one, so I'm guessing that PRG0 are images from newer carts where only one PRG chip was used and PRG1, etc. are from older carts where the density of the PRG (program) chips were less or that they used different memory management chips to allow more memory and PRG chips to be addressed. Or maybe PRG0 contains only the data from the first program chip and PRG1 contains data from the second. I have really no idea which, sorry.
As for "rev x"... Maybe an unknown revision?

I am like you. I have to many roms of the same thing. info overload
I just found any usa rom and if it played good I moved it to a new folder.
took me a long time but I now have just the usa games and only the ones I like.
