First of all, I don't want to boot gba games through AKAIO using a EZF IV. What I'm referring to is about booting the slot-2 cart through akaio. When I have the cart in the slot 2 of my ds, akaio says there's no device detected. I tried to find homebrew solutions (gbaswitch and BootGBA) but they only boot the gba screen without the nintendo logo (meaning that yet again, the cart is not detected). I know there's a simple solution: using the ds firmware menu, selecting to boot either my acekard or my ez flash iv, so this is not a "desperate"situation, but I really found this as a weird problem. Does anyone knows why is it not possible to boot this flashcard from another flashcard?
