M3 Lite Perfect

Hey, this is my first post. I've done alot of homework on which Nintendo DS cart to buy, And I've decided on M3 Lite Perfect Micro SD (with Passcard 3). And I was wondering what the wireless link compatibility is with Slot-2 DS carts (through roms) because it's a slot-2 Card, (does it make a difference?) I have'nt been able to find any information of Wireless linking (on roms) on any reviews or forums, could anyone give us a hand?

Also does the wireless linking work with GBA games through roms with the supercards?

My friend has R4 Revolution (Slot-1) for DS and he said his Pokemon Diamond linked wirelessly using the rom and flash cart to his friend who has the same card no probs.

Cheers guys
