Nitro Engine doesn't work with the current libraries of devkitARM. It's
better to remove the makefiles and to stop pretending that devkitARM is
supported. Updating the makefiles wouldn't be enough, though, it's likely
that the library will require code changes, as well as the examples.
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.
Instead of asking the user to rebuild the library, now it is possible
to build the library in both release and debug modes and to have both
versions of the library compiled at the same time.
Rendering NEA files has a terrible performance. Instead of trying to
support both formats, remove NEA and replace it by DSMA.
Some function signatures have changed to adapt to the new system.
"NE_ANIM_UPDOWN" has been removed because it's redundant: Just modify
the animation before exporting it from Blender.
