Another place where you can write cheats is in a text file. You can create a text file and save it in the game's directory. The file should contain a list of cheats, each on a separate line. You can then load the text file into the game and the cheats will be activated.
Finally, you can also write cheats using a third-party program. There are a number of different programs available that allow you to write and execute cheats. These programs can be found online and many of them are free.
