The front Obi states it includes the additional track(s) for the PS2 port as well as the original music for the arcade version. The back Obi is just an ad for the PS2 port. So both Arcade and PS2 should stay.
(btw, if we're finally able to link releases, how should we handle cases like this? Linking both the product and port page? This particular question prevents me from touching the
Tekken and
SC pages).
