No unfortunately the Action Replay is not compatible with the Nintendo DSi. There have not been any announcements regarding development or release of a product of this type.

I'm pretty sure anybody who looked at the features would know this, even before buying a DSi. They'll probably never release an AR for DSi because Nintendo can just send out a software update that'll make it incompatible again. They were going to release an AR for Wii but obviously that never happened for the same reason.

You have to remember though, anything that is being sold to people has to work no matter what. I bet if they did make an AR DSi, a lot of those people would update their DSi anyway, and if their AR no longer worked they'd complain and ask for refunds. I do think there will be a cheating method, but it won't be an AR.

This actually belongs in Dial 911 - Handheld Help. I'll move it there for you.

actually whjat i think they will make and ar for the dsi becuase a psp ar came out a couple monts ago in the codejunkies shop and the psp also has to be upgrade evry couple of months. i actually hope they make it like the psp becuase on the psp one its real time so u can check and uncehck codes as you play the game that menas no longer having to shut down/ reset everrytime u wnat to switch codes

This is all Martin Korth's fault. He [incorrectly] documented the NDS card bootup and encryption process. So everyone and their mother decided to use the shortcuts he mentioned, rather than fully implementing the spec. All Nintendo had to do was update the ARM7 BIOS to disallow said shortcuts, and all that third-party hardware is rendered useless! Brilliant?

Thus, the third-party-poopers have to release new hardware that acts like proper NDS cards. AFTER THAT, Nintendo's only chance to disable their use is by blacklist.

Of course, I saw this coming three years ago. I was just too unlucky and pissed off by that prick to bother writing a book about it. Fuck 'em. Maybe someone will learn something from this. (Probably not.)
