Until now the main makefiles of Nitro Engine have been the ones of
devkitPro, forcing users to go through extra steps to build everything
under BlocksDS.
Now, the easy makefiles are the BlocksDS ones, and additional notes have
been added to warn about the limitations of devkitPro:
- No GRF support in libnds.
- NitroFS doesn't work in melonDS.
They aren't available in the libnds provided by devkitPro. I could copy
the safe versions of the functions to Nitro Engine, but that wouldn't
help as the program would still use the unsafe versions for everything
else outside of Nitro Engine. The fix needs to happen in libnds for it
to work.
