Click on the "Cheats" tab, then click where it says "Cheat List", then "Add Code" Then type in or paste your code and click Okay.
on the gameshark
There isn't a gameshark for Pokemon pearl but you can get an action replay to put codes on.
First get a gameshark then look online for codes after that put the gameshark in the leafgreen game then type in codes. Also the codes can get you Pokemon and items instead of looking and looking you can get them easily. Most gamesharks are $15 to $20. Hope this helps ;)
No, you cannot. Because you have to put the codes into the GameShark itself and then put your game in.
go to gameshark.com-buy gameshark
The "M" code is the code that must be put on in order to get the other codes to work Gameshark stopped putting up codes for older games you can go to archive.org and type in gameshark.com or you can find it on supercheats.com
You Get a game shark for your Gameboy or Gameboy advanced
In my opinion i think the best way to get Gameshark codes is to either put it in on Google saying the game you want to Gameshark for example "Pokemon Crystal Gameshark codes" if possible go on IGN FAQS but there is also another way by going on super cheats and searching the game you want to mod
gameshark codes will be found for it on gaameshark.com or gamewinners.com i have cool codes to encounter celibi in the wild, but sadly my gameshark codes did not save :[ p.s. you spelt Pokemon crystal wrong you put cristal it is crystal by the way you should check out seribi.net for game walkthroughs
I don't know. I don't think there is much of a difference, but there are some 16-digit codes that I want and my Gameshark only lets me put in 12. I have the same question as you. A 16 - digit code is a gameshark code. But a 12 digit code is for a codebreaker. you can find gameshark codes on Xploder.com and Codebreaker codes on Codetwink.com. -Hope I helped
In order to create your own Gameshark codes, intense familiarity with hexadecimal coding is required. Pre-generated codes can be entered with ease, however, and several places supply these codes.
Careful! This can destroy your game1
