Rom extension id question

[BORIStheBLADE]

SO looking at some SNES roms I notice at the ending of the rom name there is a (j), (e), (u), [!] and etc . Could someone let me know what these mean.

Thanks.

(j) = japan
(e) = europe
(U) = us
(!) = known good dump

If you are looking to filter them down, keep the best one of each rom (eg if you are in the UK, keep the (E) roms).

ok, I'm in the us so I'll keep those. Is there a symbol for a bad/non working rom?

Thanks for the info guys. I got one more, I have N64 roms with a .V64, .Z64 and .n64. Do they all work? Or should I only keep one kind?

I use the Project64 emulator for my Nintendo64 Roms, although all of my N64 rom files are in ZIP format.   I looked in about 15 ROM files I have and all of them are "z64", although Porject64 might be able to handle other extensions ..... not sure.

Why are your ROM files not ZIP'd?

[BORIStheBLADE]

well... I unzipped them because I saw multiples in the zip. Like (j), (e) and (u) versions.

Well, my ROM files have the (U)! symbol in the "filename.ZIP" name and they only contain a z64 extension file inside.
