It's because Nintendo designed it to not be able to cheat on.
you can use your action replay on a dsi it doesnt need to be a action replay DSi to work
No. It's called the Action Replay DSi for a reason.
no,but you can buy a dsi action replay which if you hold into your ds works in bothds and dsi.
Yes, it does work on the Nintendo ds.
Nintendo made an action replay for the dsi. There is an action replay for dsi... The INITIAL codelist is different, for many games have come out since the creation of the action replay ds. However, the possible codelists are exactly the same, the action replay DSi is just not compatible with the other versions of the AR
Yes, its compatible with DSi, DSi XL, DS Lite, and original DS
No, you will need a different format of Action Replay, which will be more expensive. BUT you can use your action replay DS with it for your DS games the action replay DSi is not compatible for some odd reason -_-
If it says "Action Replay DS," it's for the DS and DS Lite. If it says "Action Replay DSi," it's for the DSi only.
You will need Action Replay DSi - the regular Action Replay device will not work.
Yes; the only real difference between the two systems is the size.
You can purchase a Nintendo DSi Action Replay in England for around £20-£30.
They have it now. I'm not sure when they released it, but it's out. You can get it at Toys-R-Us or online, somewhere where they sell games.
The Action Replay is for the Nintendo DS and the Nintendo DS Lite, while the Action Replay Max (or, sometimes called the Action Replay DSi) is for the DSi only. The normal Action Replay will not work in the DSi, and vice versa. I hope I helped! ('u')
