The Atari 2600 VCS

Of all the 8-bit development communities, the Atari developers seem to be the most cohesive. The development documents available are universal, and analysts and developers alike all use the register names in the Stella Developer's Guide. Ophis follows their lead, providing these names in the header stella.oph.

The stella.oph header also replicates two macros that appear in the header files distributed to budding VCS developers. They are documented in the file.
