Saturn Template
---------------

Presently this is just a template for building a basic Sega Saturn game. This 
code currently compiles with the following tools and libraries:

binutils-2.16.1
gcc-3.3.6
sgl-1.3

mkisofs
poweriso

Additionally, a tool for slipping in the initial program is provided, 
tools/mksatiso.c, but any binary replacement of the .iso header will do.
Likewise mkisofs and poweriso may be swapped out for alternatives in the 
Makefile. This build expects the binutils and gcc utilities to be prefixed 
"sh-". If these tools are not, please ensure you prefix them appropriately or
update the Makefile accordingly.

You will need to supply your own IP, I have not written my own yet and am
not going to host one from a licensed game or development kit here. Makefile
expects this to be named ip.bin, but feel free to get creative.

Note: If you want to build your own toolchain, it isn't hard, the above
binutils and gcc (-core) packages can be build with:

	./configure --target=sh-saturn-coff --program-prefix="sh-"
	
Be sure to include void __main() { } somewhere in the code if not in the main
file itself. This is necessary due to collect2 behavior in the gcc suite that
expects to link to libgcc.a for constructor loading in C++. First, this trunk
does not and never will support C++. Second, the libgcc.a provided with the
Saturn development kit does not implement this function, nor can I get a fresh
libgcc.a to build. You're on your own with that one, either find a valid
sh-*-coff libgcc.a library or figure out how to build one. If you pull off the
latter, please contact me at <[email protected]> or raise a PR with the
necessary instructions added to this README. Likewise, if you get C++ working
via this approach on the Saturn, feel free to invalidate the above statement
in your own fork. I just have no interest in working with C++ on this system
at this time, seems like too much overhead for the hardware.
