Using Cheats - cxNES
This is a guide for adding cheats from the NES Hacker Wiki into the cxNES emulator.
Easy cheats allow you to temporarily modify NES games like Game Genie codes, only they're more powerful, and you can have as many as you want! To use the cheats follow these instructions:
1.) First, launch cxNES and load the ROM you want to play. For this example, I'm using Super Mario Bros..
2.) Next, click on Options in the menu and then click Cheats... to open the Cheats dialog.
Looking at the Easy Cheats list on the Super Mario Bros. page, you'll notice that the first cheat is named "Start With 9 Lives (Both players)," and it has the following information:
| Addr | Val | Cmp | Description | |
|---|---|---|---|---|
|
906A | 08 | 02 | Start With 9 Lives (Both players) |
3.) We need to enter this information into the text boxes in the Raw section at the lower left of the dialog.
4.) Click in the Address text box and type in the Addr portion of the cheat, which in this case is "906A".
5.) Click in the Value text box and type in the Val portion of the cheat, which is "08".
6.) Click in the Cmpare text box and type in the Cmp portion of the cheat, which is "02". Not every cheat has a Cmp portion, if you see a dash (-), just leave the text box blank.
7.) Click in the Description text box and type in the Description portion of the cheat, in this case, "Start With 9 Lives (Both players)".
8.) Click Add and you'll see your cheat added to the list.
9.) The checkbox at the beginning of the list item indicates that the cheat is not active. You can activate the cheat by clicking the checkbox and a checkmark will appear. To deactivate the cheat, click the checkbox again and the cheackmark will disappear.
10.) Click the OK button to close the Cheats dialog.
11.) Start the game and you'll discover that you start with 9 lives instead of the usual 3! Some cheats require you to restart the game to take effect. If a cheat doesn't appear to be working, try restarting the game.
Cheats are not automatically saved or loaded in cxNES. To save them, click the Save... button in the Cheats dialog and you will be prompted to save them into a *.cht file. When you next open cxNES, you will have to click the Load... button in the Cheats dialog to load them back into the game. You can now enjoy your favorite game with infinite lives, invincibility, any power up, higher jumps, and many other game-breaking cheats.
