Summary	06938: shangonle: music stops working in senior course
Description	In Limited Edition Hang-On, stage 2 of senior course has a long turn to the left with a uphill slope. On this turn it's possible to supercharge even when touching the right edge of the road, g-force isn't enough to push player out of the track. Doing so causes a background scrolling glitch and music stops playing abruptly.
Steps To Reproduce	Play the attached inp.
Additional Information	All BGMs seem to have the same behaviour. Doesn't occur in parent set because track layout is different, no idea if there's any other clone set that uses this same track layout, or if it's possible to repeat the same exploit in any other turn in the game(s).

Thanks to a member of the club called Eliseo who helped me recording this video while I was playing. It took me more than a try to reproduce the error. 0:00-0:50 A few seconds of the attract mode and showing the cabinet, just to show this is the limited edition of hang-on 0:50-1:12 This is me testing the possible bug but failing miserably due to bad playing. 1:13-1:18 I reproduced the bug !!! Same as MAME, the music disappeared while turning left with turbo on the first curve on stage 2, senior course. 1:19-1:40 Playing for a while just to show there's no music !
