Quoted from dung:Kind of strange that stern would still have one of those to install back in 2004? Sure, sega used de branded things until they ran out and then switched over. Stern did the same with sega hardware, but the chances of them having them left over a decade after the switch? Seems fishy...
I doubt Stern installed that board. Likely the one in the game went bad and someone replaced it with the DE one that they had on hand already.
