How To Add Cheat Codes To Rom Games

Previously, we saw how to put GameShark codes on ePSXe. Now we will see how to do it on one of the best emulator of Playstation 2.

MAME will go through the Zipped file and read the cheats from the XML files inside. After its correctly installed: Fire up MAME,go to Daraku Tenshi (or any other game you wish to cheat in) and right click, hit properties, then click the Misc tab. On this tab make sure enable game cheats is ticked. After it is click apply and the close the menu. Paste the GameShark code into the box shown below, then click Add. The GameShark cheat is added. You can click the drop-down arrow to view the code to ensure it's there. Lastly, close this window and restart your game for the code to take effect. Finding cheats: GameGenie.com is a good site. The next best source is Google.

NOTE: There are another ways to do that, but firstly it’s interesting to know how things work, isn’t it? If you don’t have the emulator, you can download it from the Official Website.

This saves you the trouble of having to enter them each time the game is played. Click the Browse button and select an unzipped Game Boy/Game Gear/Genesis/NES/SNES rom - The system dropdown should populate based on the file extension - The checksum box will also be enabled for non-NES games 2. Enter the desired codes, one per line.

Open the emulator and run any game, then press ESC and check the Log Window. If you don’t have this window, enable it by clicking on Show Console, under the Misc menu. You should see something like this:

The highlighted area shows the CRC code of the game. In this case, it’s for Final Fantasy X (NTSC-J), it depends on the game. Copy the code without 0x, so it would be 6A4EFE60.

Now, navigate to the emulator installation folder (usually in C:Program FilesPCSX2, but it can be different) and open the folder called Cheats.

NOTE: By default, a folder called Cheats will also be created in My Documents. Don’t get confused with this folder, because this procedure only worked using the folder inside the emulator installation folder.

In the cheats folder, let’s create a New Text Document and rename it with the CRC code from the previous step. In this example, my file would be 6A4EFE60.txt. However, you have to change its extension from txt to pnach, which is the extension for files that store the game’s information, such as name, comment, cheats, etc. To do so, open the Control Panel, then Appearance and Personalization, and click on Folder Options. In the new window, click on the View tab and uncheck the “Hide extensions for known file types” option, like the picture below:

After applying the modification, go back to the Cheats folder, you should see the .txt extension in the file. Delete it and write .pnach instead. Now, your file name should be like this:

A simple search on the Internet and you can find many codes for your game, but most of them are still coded, which means that the emulator might not recognize them, so you have to convert them to the RAW format. There are a lot of converter out the, but I use this one, it’s simple and easy:

To use it, just put the code on the left side, specify in the Input tab what type it is (for example, Action Replay, GameShark, etc). Then, in the Output tab, always choose Unencrypted > Standard to get the RAW code. Next, click on the Convert button. Look at an example:

On the left side, the Action Replay codes:

MAX GIL

1CA898E0 1DBC9E0C

TIDUS HP MAX

1CA8B380 1455692C

1CA8B388 1455692C

Rom cheat codes

On the right side, the converted codes (RAW format):

MAX GIL

203117B8 3B9AC9FF

TIDUS HP MAX

20313058 0001869F

20313060 0001869F

Let’s use the RAW codes above:

MAX GIL

203117B83B9AC9FF

TIDUS HP MAX

203130580001869F

203130600001869F

Open your PNACH file and write following the colors:

gametitle=Your game’s name

comment=Write anything here

patch=1,EE,AAAAAAAA,extended,BBBBBBBB

// Descrição do código 2

patch=1,EE,WWWWWWWW,extended,XXXXXXXX

*If you write patch=0, it means that the code will remain disabled

Change the lines according to your codes, following the color example. In this case, the file would be like this:

Now save it and close.

Codes

Back to the emulator, in the System menu, click Enable Cheats. When you run the game, check the logs. It should be written something like this at the last lines: “Loaded X Cheats from ‘6A4EFE60.pnach'” (The name of your PNACH file). Now go back to the game and enjoy the codes!
