Summary	00992: hangon: The pitch of the engine sound is wrong
Description	The pitch of the player's engine sound is much too high. The regression occured with the change to segapcm stream_update in 0.94: SegaPCM now does stream_update on reads/writes for slightly better accuracy [Aaron Giles]

Maybe it's a copy/paste error but using a 4MHz in enduror1 gives the exact sound like enduror. These 2 are the same except for the YM.... The YM...s sound the same but the pcm sounds are different cause the pcm clock differs. Having that in mind and hearing now hangon with a 4MHz pcm clock reduces the high pitch. It's not perfect like the video but it's more like the version before it regressed in 0.94.
