Which is better an acekard 2i or an R4i?

I have an R4i that doesnt even work on my DSI. And I play a bit of a game on my lite i turn it off and the menu and the games are all gone, which is STUPID I HATE R4. I THINK I BOUGHT A FAKE, BUT THE FAKE IS BETTER THAN THE ACTUAL R4 PROBABLY. Im asking if Acekard is better cuz I don’t want the same thing to happen with my acekard. thx
