简单的说,b代表bad dump,h代表hack,t代表翻译版,a代表可选择版,o代表over dump版(b的一种)等
恩,多谢。我找到了这个:
[a] This is simply an alternate version of a 
       ROM. Many games have been re-released to
       fix bugs or even to eliminate Game Genie
      codes (Yes, Nintendo hates that device)
 A bad dump often occurs with an older
       game or a faulty dumper (bad connection).
       Another common source of  ROMs is a
       corrupted upload to a release FTP.
[f] A fixed game has been altered in some way
       so that it will run better on a copier
       or emulator. 
[h] Something in this ROM is not quite as it
       should be. Often a hacked ROM simply has
       a changed header or has been enabled to
       run in different regions. Other times it
       could be a release group intro, or just
       some kind of cheating or funny hack.
[o] An overdumped ROM image has more data
       than is actually in the cart. The extra
       information means nothing and is removed
       from the true image.
[t] A trainer is special code which executes
       before the game is begun. It allows you
       to access cheats from a menu.
[!] Verified good dump. Thank God for these!
不过您说的good tool 说明档在哪?
