|06740||Sound||Major||Random||21 days ago||21 days ago|
|Tester||Kale||View Status||Public||Platform||MAME (Official Binary)|
|Assigned To||Resolution||Open||OS||Windows Vista/7/8 (64-bit)|
|Version||0.191||Fixed in Version||Build||64-bit|
|Summary||06740: slyspy, bouldash: Sound randomly speeds up and eventually dies|
In both these games sound have issues on certain conditions (same sound HW)
In Sly Spy, between stage 7 and 8 transitions sound starts to oddly speed up, and might eventually lock up completely with a stuck tone.
In Boulder Dash this can occur between stages 2-3 and 2-4
|Steps To Reproduce||Play Sly Spy up to stage 8 or Boulder Dash up to 2-4|
Regression version around 0.106 and 0.121, where HuC6280 sound CPU has been downclocked from 3 to 2 MHz.
Also provided inps:
For Sly Spy WolfMAME 0.190 is used on secretagj set.
For Boulder Dash WolfMAME 0.191 is used on bouldashj set, I've continued on 2-4 just to make the bug to occur.

Reminds me of Crude Buster where certain sound effects caused the sound to speed up and then go back slow 00389.
Might be related somehow?

Good catch, both shares same CPUs and an IRQ tied to a Yamaha sound chip.
There must be something in the CPU execution that makes it to behave strangely ...
