Building your own ROMs using FreeWPC

The first step to rebuilding ROMs yourself is to get the source code. Download using one of the links to the left then extract into a clean directory.

FreeWPC is developed on Linux. It should be possible to use other UNIX-like systems, including Cygwin for Windows. To compile, you will need the following tools already installed and available:

• A recent copy of the gcc6809 toolchain, which includes a C compiler, assembler, and linker. If you don't have this, you can still test in native mode.
• dd, for generating the blank portions of the ROM file
• zip and unzip, in order to manipulate xpinmame ROM bundles
• The bash shell
• The make program
• Perl, for some helper scripts
• doxygen, if you want to be able to autogenerate documentation files (optional)
• Other basic UNIX utilities, like cat, rm, mv, mkdir, etc. which are almost certainly present

Configuring and making

Before you can just type make, you should create a file called .config and define what you want to build, and options for how to build it. TODO

After that, you can just run make.

Installing

If you don't declare a value for TARGET_ROMPATH, then the final outcome of the build will be a ROM file in the root of the build tree named freewpc.rom. However, if you have PinMAME installed, define it to be the location of your ROM directory. Then it will automatically be installed there.

The installation will overwrite any existing ROM zip there, but it will back it up to a file named .original. See the Makefile in machine/<game> to see which "real" ROM will get clobbered for this purpose.
