Upgrade R4 to work in DSi

I have a normal R4. Is there a way of upgrading this to allow it to work in the dsi

No, there is a hardware difference, not a software difference.Invest in an acekard 2i.

I picked up an AK2i as soon as my DSi came in the mail... Well worth it, especially since DealExtreme do them for less than $15 with free shipping anywhere in the world.

I'll stick with my DSLite
