The Supercard CIA I made. That's the one I meant. If you get an error has occured message, there's something wrong with your setup. Did you install it to emunand? If so, make sure it's installed to sysnand as well. This isn't like Slot-1 Launcher. It needs to be present on both if launching from emunand.
EDIT: CycloDS Launcher is read:
CycloDSLauncher_Test.rar
It probably won't work though. I had to change the arm7 code/ram entry address settings to get it to boot. It white screens for me. Might boot if a CycloDS is present, but it may not work with the modified Arm7 settings. Worth a shot though. Doesn't look like I can do much to save CycloDS unless there's alternate firmware compatible with it.
