For greater flashcart compatibility, with the introduction of the EDGEi version.
- Have individual makefiles for different boot files - R4iTT: ARM9 entry 0x02000800 - Amaze3DS: ARM9 entry 0x02000000 - EDGEi: Same as R4iTT, but renamed to `dsedgei.dat` - Include each makefile from individual folders, copy needed things and zip
Everything except the boot file is identical.
