The project is discontinued but the BIOS is fully functional and this page will remain.This is basically the equivalent of the Unibios for the NeoGeo CD systems.Each system requires a unique BIOS that is supplied in the ZIP file below.
See this thread for a product that allows for simple installation in both Z and top loading models. Front loading models have a DIP BIOS so it would be similar to installing a home system Unibios. The BIOS is a 27C400 (4Mbit), not the 27C1024 (1Mbit) used in cartridge systems. Power on with button A held to access a new hardware test much like an MVS would do when powered on. This method of testing relies on very few components to be functioning in order to run a complete test and is recommended if your system starts resetting, glitching, throwing exceptions etc. Stock BIOS chips do not offer any sort of self-testing for the user. Provided the option is enabled, you will see the main menu after the game does its initial load. Any settings can be applied before the actual game begins and the same menu can be accessed at any time during gameplay. Hold START SELECT during gameplay to access the main menu at any time. The SAVE option in the menu saves some currently selected settings in your systems backup RAM. During the initial load, the BIOS will automatically load any settings you have previously saved for the current game. When viewing card data, you will see (game name here) DBG for each game you save data. The smallest possible size for a save file is used to prevent too much space from being eaten by multiple games. This fix must be done for every game so it will take a while to make all games compatible. The hardware selftest provides testing for many components in the CD system, which is more than what can be tested in a cartridge system thanks to the RAM based memories.
