.............: 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. :\
