Here's the latest build of GBAMP Multiboot Selector. It adds support for MoonShell (Older MoonShell's are recommended as the newer ones that support DLDI do not load .nds files as well.) and takes away support for 3rd party GBA launchers. GBA launching will be added back on when I find a way to get the code running on DKA r20 and the newest libnds. v1.5 will be the last v1 and will have GBA booting added to it. v2.0 will likely be the final version and feature a GUI (Though I don't think it is nessisary). Enjoy!
