Dragon Warrior I [NES] [FUXED]

I know the [!] is meant to the the ROM you want to use, but mine has a [PRG0] and [PRG1] in it. I can't find just a [!] one. Can anyone tell me what that [PRG] thing is and if I should use that?

Re: Dragon Warrior I [NES]http://www.pocketheaven.com/ph/wiki/GoodCodesi think prg are fixed versions or something

Re: Dragon Warrior I [NES]I see. I was looking at another website for the codes, and I did not see anything of the sorts. Now I've to go request a normal [U] [!] ROM. Thank you.
