Holosseum is a stock System 32 board in the Time Traveller cabinet. The game hardware is completely different, the only thing it has in common is the same curved mirror projection setup to simulate the video appearing above the glass.
Also, there’s that tricky matter of capturing the LaserDisc video for Time Traveller, which isn’t applicable for Holosseum.
