Explain The Symbols In Rom Lists To Me

[spray]

i've acquired a full set of neo geo pocket roms

along with the name of the rom, each file contains what i'm guessing to be some form of language/region thing (UEJ) etc

also where there are duplicate roms, they are suffixed with a !, a1, h1 etc.

what do these symbols mean? i'm looking to just get a repeat free full set of roms, which of the duplicates should i delete?

cheers

In general I always delete the alternate and hack versions, leaving only the [!] clean dumps. Is this correct or is it usually better to keep the latest hack version?

I do the same thing, fail-proof

Hack proof can sometimes be better, as if the original game had slowdown, or there was a glitch that could be fixed by a hacking group, but most of the time its just a release group intro.
