Basic NES file header creation. PRG/CHR-ROM sizes are filled in based 

on provided prg/chr rom input args for dumping.  Mirroring is sensed &
entered for fixed mirror mappers.  So this is basic iNES file format.

Still don't have automatic banktable locating, nor mapper detection.

But this provides a basic header that should work with most currently
supported NES mappers.  If the headers need tweaked, I recommend opening
in Mesen and using it's header modifcation tool.

Some build instructions follow, but they shouldn't be needed if you're running the
released firmware on Windows.
This section needs some updating.... Don't be afraid to contact me if you'd like to build
your own firmware. Or are having issues building the host application on linux/mac
===================
Linux
Linux/Mac
===================
HOST APPLICATION:
install libusb:
sudo apt-get install libusb-1.0-0-dev
make:
gcc -I include inlretro.c -o inlretro -lusb-1.0
or just run make unix from host folder.
As noted in windows instructions below, lua must be built first
-cd host/source/lua, make o a, then make from host/source
make from host folder:
make unix
run:
./inlretro
AVR FIRMWARE:
If you want to build your own AVR FIRMWARE:
install avr-gcc and avr-libc:
sudo apt-get install gcc-avr
sudo apt-get install avr-libc
@ -486,16 +480,10 @@ So that might help if you have similar issues...
Now host app can be built from windows command prompt command make when in host directory
Currently setup to compile lua separate from host app. Need to get better at writing makefiles..
But whatever it works and saves ~12sec of compile time with current setup.
-go to host/source/lua
-make o a
-go back to host
-make
This way lua is compiled separately using it's provided make file.
make clean still deletes lua object files, so this process must be reperformed if cleaned.
-go to host
-make all
AVR FIRMWARE:
If you want to build your own AVR FIRMWARE:
Download and Install WinAVR
optional: install programmer's notepad has handy feature to make clean, all, program in tools menu
this is nifty if you are scared of the command prompt for some strange reason...
