I understand that handheld games can be just as complex and deserving of cheat/code devices, but they just don't come to mind. The Game Shark was for us Americans and the Action Replay was for you non-Americans.
(You could always import anything, of course, but officially that was the deal.) The two devices were essentially the same, despite some small tweaks and codes aimed at the respective markets.
Datel recently made an AR DSi that is compatible with the 3DS, but it seems those ones are only available from the Codejunkies website.
Instead, I picked up an AR from Meijer because I heard you could update the firmware in an AR so it would be read by the 3DS.
The device can then be used to unlock new abilities and areas for PS2 games, using an online code database that is cons[More] The Action Replay is a cheat device used for cheats and hacks on Game Boy Advance games.
The built-in codes allow players to get extra items, characters and map access in all the "Pokemon" games.
I have been following your instructions and got it to recognize the DS. Reading the thread, it sounds like you can't unplug it.
It says it is updating on the actual DS system but has been updating for 4 hours.
With Game Shark (temporarily) out of the picture, Datel saw a chance to gain new turf and began selling the Action Replay in the US.
Now, of course, Mad Catz is making a serious (and effective) effort to raise the Game Shark brand.
The particular AR I got came with the installation...
The particular AR I got came with the installation disc, so I popped it in and had to go into the Device Manager to get it to install right, but I finally managed.
It even has a little screenshot showing the file - with the copy icon - hanging over the Code Manager. Except, when I try to do this, I don't get the "copy" file icon, I get a black circle with a diagonal line running through it. What is so different about my Action Replay Code Manager that I can't drag and drop the firmware file onto it like Codejunkies says to?
