Answer 2

Action Replay DS uses real cheat codes to get to the heart of your Nintendo DS games, giving you enhancements such as Infinite Lives, Infinite Health, All Vehicles, All Levels and other exciting cheats.

Datel's latest Action Replay game enhancer has the power to blow your NDS games wide open. Action Replay DS uses real cheat codes to get to the heart of your Nintendo DS games, giving you enhancements such as Infinite Lives, Infinite Health, All Vehicles, All Levels and other exciting cheats.

Action Replay DS is really easy to use. You simply insert the supplied Action Replay cartridge into your DS or DS Lite, and switch on. When prompted, remove the Action Replay card and replace it with your game card. Action Replay recognises the title in question and offers you the title's code list. It's that easy! They're great codes too. For example, codes for the ever-popular Pokémon Diamond and Pearl include Max Cash, All TMs & HMs, Pokedex 100% Complete, Walk Through Walls, Infinite Health, One-Hit Kill and more.

Like previous versions of Action Replay, Action Replay DS is fully updateable, so you don't need to buy a new one when new games are released; just update your Action Replay over the internet using the PC app supplied. You can also enter codes manually using Action Replay's virtual keyboard. Our code creators are always hard at work on the latest DS titles, so even the very latest games will be trained and tamed within hours of hitting the shelves.

Action Replay DS is compatible with both the original DS and the DS Lite. To update the device, a PC running Windows XP and connected to the internet is required (product is not Vista-compatible).

Gameshark is an illegal mod and lets you change the coding of the game. This is hard to use and can be frustrating. For instance if I wanted my character to walk through walls or look like a chicken, I could do that with Gameshark. Be warned whatever changes you've made to the game are permanent and can really mess up your game.

Codebreaker is pretty much exactly what your friend said and is used for consoles like Xbox, PS2 and so on.

Action Replay as far as I know it's Legal, as it can be bought off Ebay. I got all the information about Action Replay from this site:

Code Breakers and GameSharks are Illegal, or at least definitely not recommended.

Action Replay is the easiest to use.
