You mean in the filename of roms you get? That'd be from the tags the GoodTools sorting utilities label files with:

.............: STANDARD CODE NOTES ::............
:                                              :\
: [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).  :\
:            -------------------              :\
: [b] A bad dump often occurs with an older    :\
:    game or a faulty dumper (bad connection). :\
:    Another common source of [b] 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!  :\

:                                              :\
: **** SNES ****                                :\
: (BS) These Japanese ROMs were distributed    :\
:      through a satellite system in Japan      :\
:      known as the Broadcast Satellaview.      :\
:      They were transmitted along with a TV    :\
:      show which was connected to the game in  :\
:      some way. These games were only playable :\
:      during the show, and thus stop after an  :\
:      hour, and many were timed so that only  :\
:      certain time periods were playable.      :\
:            -------------------              :\
: (ST) The Sufami Turbo device allowed two      :\
:      GameBoy sized carts to be plugged into  :\
:      the SNES. Certain carts combined into    :\
:      new games much like the Sonic & Knuckles :\
:      lock-on technology by Sega.              :\
:            -------------------              :\
: (NP) Nintendo Power has been known to release :\
:      games only available to its subscribers. :\
:      Most of these ROMs are Japanese, as this :\
:      practice occured mainly in Japan.        :\
:            -------------------              :\
:                                              :\
: **** Genesis ****                            :\
:  (1) Carts with this code will run on both    :\
:      Japanese and Korean machines.            :\
:            -------------------              :\
:  (4) While this code is technically the same  :\
:      as a (U) code, it is a newer header      :\
:      format and represents that the cart will :\
:      run on USA and Brazil NTSC machines.    :\
:            -------------------              :\
:  (B) This country code indicates that the    :\
:      cart will run on any non US machine.    :\
:            -------------------              :\
:  [c] This code represents a cart with known  :\
:      faulty checksum routines.                :\
:            -------------------              :\
:                                              :\
: **** GameBoy ****                            :\
: [BF] Bung released a programmable cartridge  :\
:      compatable with the GameBoy which could  :\
:      hold any data you wished to play.        :\
:      However, many games do not function on  :\
:      Bung v1.0 carts and have to be 'fixed.'  :\
:            -------------------              :\
:                                              :\
: **** Nintendo ****                            :\
: PC10 The PlayChoice 10 was an arcade unit    :\
:      which played exact copies of NES games  :\
:      in an arcade cabinet. The machines had a :\
:      choice of 10 games to choose from and    :\
:      ran for about 3 minutes on 25 cents.    :\
:            -------------------              :\
:                                              :\
:  VS The Versus system ran on similar hard-  :\
:      ware to the PC10 machines, but simply    :\
:      allowed you to play against each other.  :\
