The ndstool -c main.nds -9 main.arm9.bin call could be done if the apptype is arm9 to simplify things for starters, no?
Yes, but leaving arm9.bin file too, that will be used in case of mixed sources. Though a starter could be confused because in this way the compiler will create two executables instead of one (main.nds and main.arm9.bin)
