Hello, sorry if this has been asked before, but I was wondering if there are any good flashcarts which are able to play GBA games on a DSi. I own a EZ flash 3 in 1 expansion pack on my DS lite, but I find that to be not as lasting as I hoped, since the provided battery runs out really easily (I've tried changing batteries, it doesn't work somehow). I haven't been playing my DS in a long time or paid any attention to DS news, but the last I heard, they were developing a flashcart which can load GBA games using the DSi's own RAM, so it doesn't use any batteries. Has this cart been made? If so, I may just get myself a DSi.
