This cart works with a "non-official" version of WoodR4 1.29.
I has updated my cart, and it works perfectly on DS and 3DS with woodR4 1.29.
Can DStwo play GBA games with EZflash 3-in-1 expansion pack without GBAexploader?
Others carts can play GBA games directly. Like R4 with Wood, Acekard2i with AKAIO, EZFLASH V/Vi or CycloDS. But I can´t do it with DStwo.
