The GoodXXXX series is a naming method and series of programs used to label and verify ROMs.

Country Codes

  • (U) - The game is from the US and is in English
  • (J) - The game is from Japan and is in Japanese
  • (E) - The game is from Europe and is in English
  • (JU) - The game is in English and Japanese
  • (1) - The game is from Japan and Korea
  • (4) - The game is from USA & Brazil NTSC
  • (A) - The game is from Australia and is in English
  • (F) - The game has a world release
  • (PD) - The game is in public domain
  • (Unl) - The game is unlicensed

Standard Codes

  • [!] - The game is a verified good dump
  • (aX) - The game is alternative to the original copy
  • (bX) - The game is a bad dump. These are useless. 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) - The game has been hacked
  • [h1C] - Further identifies a hack as a cartname 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) - The game has been supplied with a trainer
  • (x) - Wrong checksum (Needs verifying). Potentially- [c][!] or a bad dump

Genesis-Specific Codes

  • (1) - Carts with this code will run on both Japanese and Korean machines.
  • (32X) - 32X game
  • (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.
  • (J-Cart) - Codemasters J-Cart
  • (MP) - MegaPlay (only Sonic 1 is in Goodgen)
