I was going to buy a DSTT, but then somebody on here suggested a Acekard 2i for my DS Lite. So I'm going to buy one from shoptemp.com, but I have a few questions before I buy it:

1) Can I use wi-fi with it?
For example, can I play Pokemon Platinum and battle/trade someone with wi-fi, like the DSTT.

2) Is it possible to enter Action Replay codes on it?
I had an action replay but I lost the disk so it can work, so this is one of the main reasons why I'm going to buy an Acekard.

3) Can you copy and paste AR codes on it and use them in the games?
If I make a Pokemon AR code with Pokesav, can I enter it somewhere in my microSD card so it can work in the game?
If you have a link for a tutorial on this I would appreciate it!

Thanks in advance!
