It's not really any different to the set we have, except it's an original seibu set rather than the china? license
Gotta admit i do find the Seibu V33 based hardware interesting apart from the differences in the protection schemes the games use also in the sense of what other games might have been supported on this platform..?? certainly there is supposed to be a Raiden II 2000 running on as yet unknown hardware maybe it uses the Seibu V33 varient..??.
For a while i held out hope that maybe some of the games in the Legionnare driver might have had a re-release on this platform the most likey being Seibu Cup Soccer as it was developed by Seibu but i've kinda given up the ghost on that now.
