The primary arcade machine emulator is MAME, and it has a very specific format for romset compression. I have previously started a project call pyros that allows the creation and update of MAME romsets. The project consists of the following tools:
- pyrex: Tool to create an executable Bash script that will take unorganized files and put them into an organized MAME romset.
- pyrat: Tool to create a Romset Data File, or RAT, from a romset. A RAT file represents the organization of the romset, without regard to the emulator-specific data that is usually found in other emulator data files.
- pytz: Zipfile creator that follows the torrentzip specification
The tools interact in this order:
- pyrat: First the necessary data is generated into a RAT file, either from another DAT file or from an already-existing romset
- pyrex: Using a RAT file, existing files, and a destination directory, a Bash script is generate that will create a romset
- pytz: The script from pyrex uses the pytz tools to create the romset.
I have been working on the Pyros project for some time, and would really like to see it's release sometime soon. The project has revealed several bugs and new features for the Python project that has gotten me involved upstream.
