I've downloaded many roms off the net and have always wonderd what the few letters after the roms name mean. For example :-

Zero Tolerance (jue) [x]

Now Ive got a good idea that (jue) means Jap, US or Europe but I dunno what the other letters mean. On some of my others there are also the letters [a], [c], [h1], [h2], [h3], [h4] and sometimes just numbers. Has anyone got an idea of what they mean?

Those are codes used by Cowering's ROM renaming utilities (GoodNES, GoodGen, GoodPCE, etc.). There's a full list in the documentation, but from what I remember:

A - Alternate version (correct dump, but of another version of the cartridge)

C - Bad checksum (?)

H - Hacked

X - Bad header (?)

! - Verified good dump

A number instead of J, U, or E - Released in another region, most commonly I've seen (4), which I believe normally indicates a Brazil version.

I'm not 100% sure on these. RTFM .

download goodgen (i.e. at zophar.net), it also contains a list of codes used in the names.
