Game is running at incorrect speed like fast forward
Thread for the game is here http://forums.ppsspp.org/showthread.php?tid=1278&highlight=unbound+saga

I did some testing and the game was fine with 0.7-563 and broken after this build(couldn't find 0.7-564)

Perhaps it's this:

github.com/hrydgard/ppsspp@218c891

Could you, on Windows, go to the Debug menu and save out a map file, and put it in a gist/pastebin? That'll show if it's using vtimer funcs or etc.

Thanks. It's definitely using vtimer funcs so it's probable that commit broke something.

It uses:

sceKernelGetVTimerTime
sceKernelStartVTimer
sceKernelStopVTimer
sceKernelCreateVTimer
sceKernelDeleteVTimer

So it's one of those functions misbehaving.

Has this improved? I think the problem with vtimers has been fixed.

Nope, even as of the latest revision (0.8.1-1233 github.com/hrydgard/ppsspp@da1c59fa75) it's still running as if fast forwarded, with jerky characters and actions.

This game doesn't even import many things for frame timing. The most likely suspects are above.

If you find each one's DEBUG_LOG (e.g. DEBUG_LOG(SCERTC, "sceRtcGetCurrentClockLocalTime(%08x)", pspTimePtr);) and change to NOTICE_LOG, are there any functions called frequently? sceKernelDelayThread only if it's with a relatively large parameter value (e.g. 10000 or more.)

I guess the most probable one is vtimers, if none of the above show up as being called a ton.

Could possibly be improved with vtimer fixes, can you test again?

@unknownbrackets

The game's abnormal speed is now definitely fixed with the vtimer fixes (circa v0.9.1-2145-gbadf33a) and is playable. (well at least as far as I've tested)

This issue can be closed when verification is obtained from another tester. Nice work @unknownbrackets

EDIT: In a completely unrelated(?) issue, the sound effects (from punching, kicking) and voices cut off/fade away after a short while in game. The BGM playback is completely fine however.

So they keep playing but die out too early? Maybe it's ADSR related, or it could still be issues with timing. But probably better as a separate issue.

I'm going to go ahead and close this, if anyone is still experiencing problems with it running too fast, please comment. If there are more issues later, probably better as separate issues.
