(I've cross-posted this from the Acekard forum as I'm not sure it is Acekard specific) I have just started using an Acekard 2.1 with a new DS. I am having problem playing multiplayer games (specifically FIFA09 and Brain Academy) with another DS (with no card in slot). I can establish initial communication, but when trying to download the software, after a few moments the transfer stops and I receive a message such as "Communication discontinued. Turn off the power" on the child DS. The host just sits there still trying to transmit. Setup: Acekard 2.1 with 2GB Kingston MicroSD. Latest AKAIO. 2 x DS Lite I have tried a) Enabling Download play in ROM b) Enabling Download play globally c) Using AK2 loader The problem persists. Any ideas? Am I supposed to be able to do this with a flashcart?
