Oh great! Play music issue just solved, thanks!
With cd tracks enabled it's another game, still better

..What about play intro issue? On OS4 intro works with 24bit screens on MOS I'm not able to enable it in any screen's depth/resolution.
Anyway under MOS Wipeout2097 game it's nearly perfect, plays surely better than OS4 at this moment.
Also joypads are better supported.
