Title: NES ROM Naming Convention?
Post by: wxforecaster on October 02, 2010, 10:46:37 am

Upfront apologies if an existing thread covered this somewhere...couldn't find it.

Trying to pair down my NES ROM list where there are in some cases 8-10 ROMs for a given game. Is there a "Space Balls Secret Decoder Ring" for the naming convention somewhere?

My roms have tags between the ROM name and .nes suffix like...

(U), (E), (PRG0), (PRG1), (KC), (PC10), (A),  [o1],  [o2],  [o3],  [o4],  [o5], [p1], [p2], [!], and surely others I've missed.

Thanks in advance!
Evan

OK, to be up front. Most of my links regarding this topic are dead, and for good reason.

However, one group did bubble up to the top and it looks like one I can safely link to here. Check out http://en.wikipedia.org/wiki/TOSEC (http://en.wikipedia.org/wiki/TOSEC) and look for the document "TOSEC Naming Convention."

I believe NES Roms are using the Good Naming convention

http://en.wikipedia.org/wiki/GoodTools (http://en.wikipedia.org/wiki/GoodTools)

U, E, and J are regional designations.  U=USA E=Europe J=Japan

Good Code    Meaning of Code    Explanation
[!]    Verified Good Dump    The ROM is an exact copy of the cartridge; it has not had any hacks or modifications.
[a]    Alternative version    The ROM is an alternative release of the game. Many games have been re-released to fix bugs or to eliminate Game Genie codes.
   Bad Dump    A ROM image which has been corrupted during its distribution. They often have graphics errors or sometimes don't work at all.
[f]    Fixed Dump    A fixed dump is a game that has been altered to work better on a flashcart or an emulator.
[h]    Hacked ROM    The ROM has been user modified, with examples being changing the internal header or country codes, applying a release group intro, or editing the games content.

•    Overdumped ROM    The ROM contains some non executable data in it. It doesn't affect the game at all, it just makes the ROM bigger.

[p]    Pirated version    A dump of a pirated version of a cartridge; they often have their copyright messages or company names removed or corrupted.
[t]    Trained version    A trained ROM is a ROM which either has been hacked to include cheats, or includes a cheat menu for users to use cheats ingame.
[!p]    Dump Pending    This is the closest dump to the original cart but the proper ROM is waiting to be dumped.
