Hacking New Dsi player, looking for flashcard

[princess99]

OK so I used to have a DS and I still have my DSTT R4 card, my first question is there a way to use my old card in the DSi? If so how?

If not.. where is a trusted website to buy a flashcard for the DSi?? My old card came from www.ndstt.com and I see they are now http://www.r4wood.com/, this is so confusing and I can see there are so many scam sites out there I want to get some advice before I buy...

Again I have a DSi now, would like to get a 3DS so a card that would work for both would be nice, thanks

If your DSTT doesn't auto-boot then you can probably run it on your DSi through an Action Replay DSi. Otherwise you need a new cart.
Reliable sellers: nds-card.com(china), modchipsdirect.com(NA), dsflashcart.com(NA).

R4i Gold 3DS(r4ids.cn) is the most recommended card around here, you can't go wrong with it.
