Hacking Best slot 2 card to use with R4?

[Lava Mage]

I have a R4 and am looking to buy a slot 2 flash card. I do not know if their needs to be combatability between your slot 1 and 2 cards so I am asking here. Also, I am having trouble finding places that sell the cards anyway. So if someone can suggest a good card to buy I would appreciate it very much. Thank you!

(I do hope this goes here and not the GBA hardware section

)

I second that

Unfortunately, I have a DS phat, and from the looks of it the card only works on the lite.

IIRC, there was a phat sized version of it also.
