I was a little cautious of switching discs like this, but donвЂ™t worry, everything works swimmingly. When one is ready to start, the system will prompt the user to remove the GameShark disc, insert the game, and press X.

IвЂ™m not sure why anyone would go to the trouble to insert the GameShark disc if they didnвЂ™t plan to use the codes, but the option is there nonetheless. Once youвЂ™ve selected the codes you want to begin with, youвЂ™ll have the option to start the game either with or without codes turned on. Once saved on the memory card, theyвЂ™ll always be available for easy selection. Completely eliminated is the need to look up codes before playing a game. It takes a little time to enter all this information, but itвЂ™s very useful and much better than having to type in codes each and every time a game is played. When adding codes, the user can type in the name of the game and the name of the effect. Unlike Game Genies of the past, the user rarely has to look at the actual codes as everything is nicely translated into words. One selects the game theyвЂ™re about to play, looks at all the available codes, and chooses which ones they want activated for the game. ItвЂ™s a nice big menu with TONS of games listed. The system will boot up as normal and load the GameSharkвЂ™s interface. With a memory card with some spare space available, the user can even add codes to the already large database without having to type them in each time.ДЇirst, one must insert the GameShark disc like any other game. The GameShark itself is a CD that вЂњloadsвЂќ these вЂњcodesвЂќ into the PlayStation before a game starts. Instead of the cartridge вЂ“ game intermediary, third-party developers had to get a little more clever when CD-based gaming became the norm. GameSharks represent the industryвЂ™s evolution from the Game Genie. It would seem that several previous versions exist with entirely different interfaces though I cannot speak to the quality of any others. What the differences are between how these 2 iterations function is unknown to me, though generally newer editions of items like this improve upon older ones and IвЂ™m perfectly happy with my disc.

In addition to the CD-version in my possession (Version 4.0), there was also an earlier version that fit onto one of the ports of the back of the unit.
