Here is a Sega System 16 Altered Beast PCB with a Jamma Adapter that
allows you to change the buttons if desired (this is the JAMMA adapter: https://www.arcaniac.com/products/sega-system-16-24-to-jamma-adapter).
-The Altered Beast PCB plays and sounds good and all attract mode looks
normal and controls work. To desuicide the board, the sound processor
has been changed to a Z80A processor and a decoded A10 ROM has been
installed.
-After level three, the background graphics appear garbled and the
intermission graphic appears garbled (the character sprites and menus
are fine), though you can continue to play the game to the end. I would
guess there is ROM data for these last boards that may need to be replaced
for those graphics. The board otherwise seems to function fine, I am not
an expert on this hardware.
-This would potentially be a great board for the Sega System 16 multi which installs replacement ROMs on the board.
$178 shipped to USA destinations. Includes the Altered Beast PCB and the
JAMMA adapter (also included is the original sound processor and A10
ROM.)
