Cheats

Cheats are stored in an ini format file, 'jnes.cht'. When Jnes loads a rom, it calculates the CRC of file (VROM and ROM), it will look it up in this file, if a match is found any cheats under it will be loaded for that game. There is a dialog for cheats in the user interface that you can use to add, toggle, and delete existing codes. For example, if you wish to enter a multi-part game genie code, separate each one by dashes and no spaces.

There is a user interface for modifying cheats, however here is a brief description of the format in the actual cheat file for game genie. Please take note that in one line you can specify up to 3 codes by separating them by dashes, just like the dialog.

[Signature]
Name=TITLE
Code0=GGCODE1-GGCODE2-GGCODE3,Description
...
Code127=GGCODE,Description

• TITLE: the name of the rom, useful for keeping track of codes
• GGCODE: is the actual code string, either 6 or 8 characters
• Description is displayed in the cheats dialog

The emulator has to generate the signature section labels as described above.

Cheat codes may cause your game to behave unexpectedly, use cheats at your own risk. Jnes also suports Pro-Action-Replay cheats, use the cheats UI in Jnes to modify these cheats.
