This command will build a file called “adventure.nas”, an HEX formatted binary file suitable to be run on the existing emulators.
It is possible to choose a full VT/ANSI emulation or a tiny console support. The ANSI version of the library depends a bit less on the ROM because the video memory is addressed directly.
You can also change the program location with the “-zorg=” option. The default position is at address $1000.
