The GoodTools is a collection of programs for Windows created by Cowering to label and organise ROM files. The tools cover a variety of older consoles and computers, each of which has its own GoodTool to manage its own particular set of ROMs. The tools themselves can perform a variety of functions, including renaming ROM files to match the GoodTool conventions, sorting ROMs into folders depending on their labels, and generating a list of missing ROMs.

Sega consoles currently covered by GoodTools are: Sega Mega Drive (including 32X), Game Gear, Master System (including SG-1000) and Pico.

Standard Codes

  • [!] - The game is a verified good dump
  • [aX] - The game is an alternative re-release 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.
  • [fX] - A fixed game has been altered in some way so that it will run better on a copier or emulator.
  • [hX] - The game has been hacked
  • [h1C] - Further identifies a hack as a cartname hack
  • [oX] - 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.
  • [pX] - A pirated version of a ROM Image. Usually the copyright messages and company names are corrupted/removed.
  • [tX] - The game has been supplied with a trainer
  • [T+XXX] - Most recent version of a ROM translation
  • [T-XXX] - Obsolete version of a ROM translation
  • [x] - Wrong checksum (Needs verifying). Potentially- [c][!] or a bad dump

  • (A) - equivalent to (U)
  • (B) - This country code indicates that the cart will run on any non-US machine.

  • (J-Cart) - Codemasters J-Cart
  • (MP) - MegaPlay (only Sonic the Hedgehog is in GoodGen).
