    Default Game Genie Code Creator Tool (Genesis/MD/SCD/32x)

    Game Genie Code Creator. This program will try and make a Game Genie code from a RAM address that you enter. Will work on Sega Genesis, Mega Drive, Sega CD, and 32x. It has an optional code search filter which is useful if you happen to know the amount that you start with for your RAM address. Example: If you start a game with 25 grenades, you would enter the RAM address for grenades, enter 25 as the number for the filter, and check the box. The program will only show possible codes where 25 is being moved to that RAM address. From this, you can make a "Start with more grenades" code. If you don't know what number you start with, or if you're searching for other types of codes, just leave the box unchecked, and it will show you all the possible codes, along with the value from the ROM that is being moved to your RAM address.

    The "Infinite" type code search only works if the value of your RAM address is being subtracted by one at a time (lives, ammo, timers, clocks, continues, etc). May add more code support in the future.

    Since there are so many different ways to program games, the program will obviously not work in many situations, but it should be useful for people that want to try and find Game Genie codes for games that don't have the code they want, or doesn't have any codes at all.

    Here are a couple screen shots using that recent Sonic 1 prototype ROM, and the RAM address for lives (FFFE12). It made a "Start with more lives" code, and an "Infinite lives" code (both seem to work fine). These codes are different than the codes for the final release of Sonic 1.

    Added Game Genie encryption to the Game Genie Code Creator tool. Many thanks to rimsky82 for the encryption dll.

    For Game Genie codes that use a replacement instruction, it just gives you the encrypted Game Genie code. For Game Genie codes that allow you to adjust the value (lives, ammo, health, level, etc), the program lets you select whatever value you want, and then click a button to get the new encrypted Game Genie code.

    Thanks.

    This newest version now has 16-bit support for filtered searches and replacement values.

    Since the program knows if the value you're trying to make a Game Genie code for needs to be an 8 or 16 bit value, it will not let you use a value larger than 255 if the game is expecting an 8-bit value.

    In the screenshot, you can see that it is an 8-bit value in the ROM (04), and I'm trying to use a value greater than 255 (2748). It will show you a message telling you that your value is too high, and that it's setting your replacement value to 255. You can then adjust your value to a value between zero and 255 and get your new Game Genie code. Note that every time one of your code matches is an 8-bit value, a "Only use values up to 255" message pops up.
