Using Cheats - FCEUX
This is a guide for adding cheats from the NES Hacker Wiki into the FCEUX 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 FCEUX and load the ROM you want to play. For this example, I'm using Super Mario Bros..
2.) Next, click on Tools in the menu and then click Cheats to open the Cheat Search 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 at the lower left of the Cheat Search dialog.
4.) Click in the Name text box and type in the Description portion of the cheat, in this case, "Start With 9 Lives (Both players)".
5.) Click in the Addr text box and type in the Addr portion of the cheat, which in this case is "906A".
6.) Click in the Val text box and type in the Val portion of the cheat, which is "08".
7.) Click in the Cmp 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.
8.) Click Add and you'll see your cheat added to the list.
9.) The asterisk (*) at the beginning of the list item indicates that the cheat is active. You can double-click the list item to deactivate the cheat and the asterisk will be removed. You can reactivate it by double-clicking it again.
10.) Close the Cheats Search 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.
Your cheat will be implemented and saved automatically. You can now enjoy your favorite game with infinite lives, invincibility, any power up, higher jumps, and many other game-breaking cheats.
