I mistook your id for one in an earlier discussion. Further I had
mentally carried over the discussion of emulators and misread your
earlier post.
The two exceptions to all free software I'm aware of are:
The FSF documents on BIOSes say when they were fixed in ROM and
realitively simple the FSF had no interest. RYF Certification
Guidelines[1] also say:
"However, there is an exception for secondary embedded processors.
The exception applies to software delivered inside auxiliary and
low-level processors and FPGAs, within which software installation is
not intended after the user obtains the product. This can include,
for instance, microcode inside a processor, firmware built into an
I/O device, or the gate pattern of an FPGA. The software in such
secondary processors does not count as product software."
There is at least one probably free software game for the SNES
http://secret-maryo-chronicles.en.softonic.com/ . So arguing a game
is not software when there is software would be a bit strange.
In short The SNES has a microprocessor (6502 IIRC), is therefore a
computer and the games are software.
