Unfortunately I don't have a o3ds but I'll try to take a look at rxtools sources.Anyway to boot rxTools? rxTools has an "arm9loaderhax.bin" file, but it won't work with CtrBootManager9. If I completely remove Ctr and paste the rxTool's "arm9loaderhax.bin" in the root of the SDcard, it will boot. But if the rxTool's "arm9loaderhax.bin" is located inside eg SDcard\rxTools\arm9loaderhax.bin, it won't boot.
