There are 7 games:
Fighting Board:
Samurai Spirits 64 (exists in normal and censored korean version!)
Samurai Spirits 2: Warriors Rage
Buriki One
Fatal Fury: Wild Ambition
Shooting Board:
Beast Busters: 2nd nightmare
Driving Board:
Roads Edge
Extreme Rally
I own the four fighting games and I think that their gameplay is GREAT! FFWA is like a simplyfied RB2, Buriki One it totally unique and the two Samurai games provide phantastic atmosphere and very very very decent gameplay!
There are also different Mainboards out there:
-Old, not 100% Jamma Fighting Board with +5V
-100% Jamma Fighting Board
-Samurai Board (plays SS64 and SS2:WR)
-Shooting Board
-Driving Board
FFWA was released on the Playstation, but it looks crappy and plays not as good as the Hyper version. Many Combos are missing, lower resolution, no animations in the background etc.
The WarriorsRage game for the PSX (WarriorsRage2) is the sequel to the Hyper SSWR game. The gameplay is good, but the graphics are below PSX standard. The US version of this game is fairly rare.
I can reccommend the Fighting Board with all four games 100%...get it if you can, but watch out for SS64, the korean version is really lame and switching the language won't help! So be careful and get the japanese version!
