San Francisco Rush in MAME

Pages: (1/1)

Bigtymer781:

I was wondering if anyone has tried playing San Francisco Rush in MAME, I recently got a CPU that could run the game at full speed most of the time. The only problem I have is that the sound is out of sync with the video, like 2 seconds behind actually. I'm curious to know if anyone else is having this same problem? The game should be running at 57hz and its only running at 30hz, even if I manually set it higher, maybe this has something to do with the sound being out of sync?

Source Changes
--------------
Added new tool ldresample to assist in resynchronizing audio tracks in
a CHD with frames. Currently still WIP but useful if you know what
you're doing. [Aaron Giles]


Does anyone know how to use the new ldresample tool, or where I could find directions to?

When I type ldresample at the commandline, I get:

--- Quote ---Usage:
  ldresample source.chd
  ldresample source.chd output.chd offset [slope]

Where offset and slope make a linear equation f(x) which
describes the sample offset from the source as a function
of field number.

Looks like offset move the sample and is for correcting is all samples are same amount off.  Slope is if the amount off changes (constantly) over time.
