I'm currently in the process of doing this for the 65816 processor.
This is a 16-bit processor most popularly used in the Super Nintendo
Entertainment System.
Neat stuff, Jay. I was not aware of this.
p.s. Why the 65816? It's really simple to understand the whole thing
and the constraints enforce tight code. The x86 is too complicated for
me right now and it would be too cushy, I think.
X86 is a monstrosity. :)
Another advantage you didn't mention, if you're targeting the SNES
hardware in particular, is that a lot of people are already set up with
emulators, and I suspect there's an enthusiast community that would try
any programs (ROM images) people create with this.
If other people want to play with approaches like Jay's, some other CPU
architectures with interesting applications are ARM (smartphones and
other low-power devices), MIPS[*] (cheap home network routers that can
function as general-purpose computers), and the hobbyists'
microcontroller platforms like the Arduino. RISC is your friend.
People also like to play with popular old architectures like 68K, 6502,
and Z80, but I can't think of great practical application for those.
Maybe you could produce something more interesting than C as a macro
assembler for 64-bit architectures (maybe a DSL angle?). There's also
the JVM and Dalvik. Oh, and GPUs.
[*] I believe that there is already a more ambitious project involving
Racket and MIPS, so you might want to pick one of the others, just for
more variety.
