Version 1.0 = Initial public release.


There is a Help buttom in the program that should answer any questions.

This program will try and make a master code for any Sega Genesis or Mega Drive game.  This is useful if you have a game that no one has made a master code for.

This program will not work on EA (Electronic Arts) games.  I made a master code program for EA games, which you can find on my site.

What a master code does: If you are using Game Genie codes, patching Game Genie codes into your ROM, or doing any kind of changes to your ROM, and you get a blank red or black screen and the game won't run, a master code will usually fix that. It fixes any kind of checksum issues.

There are a ton of different ways that game companies do checksum checks. This program searches for one of the more popular methods and makes a code for you. This program will work on a lot of games, but there are also a lot of games that it will not work on.  If I get enough feedback, I will add more compatibility in future releases so that the program will work on more games.

Shouldn't need any additional files if you're using Windows.  It uses the .net framework.
