573in1 is a full-featured homebrew maintenance and troubleshooting tool, game installer and BIOS ROM replacement for arcade games based on Konami's System 573 PCB, such as earlier versions of Dance Dance Revolution and other Bemani rhythm games from the same era. It currently allows for:
- dumping, erasing and writing images to the onboard flash memory, PCMCIA flash cards and RTC RAM;
- dumping security cartridge EEPROMs and editing the serial number stored in them in order to reinstall a game on a different system;
- repurposing cartridges for use with any game that uses the same cartridge type;
- browsing the CD-ROM, or any attached IDE hard drive or CF card, and launching System 573 and PS1 executables.
Download and usage
The latest version of 573in1 can be found on the releases page, accessible through the GitHub sidebar. The tool is available in three different formats:
- as a CD-ROM image, usable on any 573 equipped with a CD-ROM drive (including ones fitted with BIOS mod boards);
- as a BIOS ROM image, allowing the system to boot directly into the 573in1 main menu (even with no IDE drives connected) and optionally launch a game or custom executable automatically;
- as a standalone 573 executable for advanced users.
See the documentation for more information and usage instructions. Reading the documentation before proceeding is highly recommended.
Contributing
Pull requests are welcome. If you wish to add functionality (e.g. game-specific menus to manipulate user data, extract assets and so on) feel free to do so, however please stick to the following guidelines:
- Do not include any code lifted as-is or minimally modified from a game disassembly. Rewritten and properly explained/commented code is fine.
- Do not include any Konami game files or excerpts thereof. If necessary, only include metadata about the files such as hashes, offsets, sizes and so on.
- Store any such metadata as a file in the resource archive (see
resources.json) rather than hardcoding it. If possible, provide a copy of the scripts used to gather the data from the original files in thetoolsdirectory. - Adding a section to the documentation covering usage of the newly added functionality is not required, but would be highly appreciated.
