This release includes a refactoring of the console & printer routines out of the BIOS and a refactoring of the board-specific I/O libraries out of the lib directory and into libretro and libnouveau.
By default, the retro will be built in the usual manner.
To build for the Nouveau, create a Make.local file in the top directory with the following in it:
ASM_FLAGS=-I../lib -I../libnouveau
BOOT_MSG=Z80 Nouveau 2067-1.1
