It runs and appears to play the boot animation correctly, however it hangs after loading the game binaries. (from what I can tell after re-enabling the debug display box code stuff. It displays 3 red boxes then a blue, then the screen is cleared. I assume this means it didn't detect an error and attempted to launch the game) Seems like something in new libnds/devkitarm is breaking something. Someone will need to debug this and find out why. This issue isn't something I can resolve alone sadly. Until this is fixed the previous build will remain until this is resolved.
