wonderful
that thing is awesome i haven't seen something like again

Not for DS users
The DS save backup doesn't work for many games, certainly not worth it if that is why you want this product. The GBA code side works fine.

Very Dissatisfied
Although the name suggest it's an action replay for both ds games and gba games. It is only an ar for gba games and a back up file saver for ds games.

alsome!!!
this thing is the best thing in the world i have ever seen.

Looks good
I think its a good product. 1 good thing is u can download ac:ww map editor and use this to edit animal crossing wild world saves!

Pretty good
Oh and umm aaron all u need to do is hook it up to ur computer and use the reset feature (all codes will be gone)

THE BEST EVER!!!!!!!!!!!!!!!!!
it is the best thing ever!!!!!!!!!!!!!!!!

good but could do better
I havent used the gba side of but the ds save backup feature is a great addition. However it does have some problems.

It cant recognise or backup saves for certain games. The newer versions were fixed so they would work with animal crossing & mario kart ds.

However no version so far will let you backup your save file for pokemon diamond or pear as its a unsupported save type.

GOOD
the action replay it's very good

need help
its really relaly good to have and i liked it but it tells me right now witch i dont no how to do is device i corrupted please reset your device to factory settings

No title

cool
get it .its really good

Don't be fooled
This device is NOT compatible with DS games. Yes, it WILL not work on DS games, only with GBA games. The interface is sucky and you can't even edit a cheat properly without having to affect the whole system. Not to mention that if you turn off the game while the cheat is being loaded, it WILL delete the whole cheat and leaves you with nothing. This device is just desperately poor and leaves a bad taste in your mouth. Quality wise is just plain disgusting, except that you get a fancy metal box that comes with it.

tungi2 is RIGHT
All of my first party Nintendo DS games will NOT register with the AR Max. My other games like Sonic Rush and Castlevania work fine though. What in the world is going on?

get this one
If your going to get a cheat device, this is the brand to buy. They come out with cheats for every Gameboy Advanced/SP, and DS games. If you have trouble downloading you can always enter the codes manually on their web site.

problems
This cheating system is pretty good. it worked like a charm on pretty much every gba game i have... BUT it has some problems with connecting to the computer thru the usb cabel. so this can sometimes be a problem

the best cheat pak
this is so cool it works on my ds and gba and works for all of my games

Da best
Max Duo is da best cos of the way u can create multiple game saves and I am relieved to find an action replay which you don't have to use for cheating. Cheating in games is wasting games. You get such a warm satisfying feeling when you cheat your way through a game (sarcasm).

Bad !!
Action replay max duo can not load cheat to nintendo DS, its just transfer the save file to your computer, the only cheat program is just GBA, it's olso bad !! not all game works
