Star Wars Trilogy Arcade running in slow motion

[belegdol]

Hello,
Star Wars Trilogy Arcade is running in slow motion for me despite the emulator showing 60 fps. According to the information I was able to gather this issue should be affecting only one of the revisions but for me it appears to affect both swtrilgy and swtrilgya. Error.log when running swtrilgy:

Both revisions display "Wait setup this feedback lever" upon startup. It takes about 45 seconds from when the crosshair appears at start of the Yavin stage until the "You've got one on your tail" moment, whereas it should be taking about 25 according to youtube captures:

This is with self-compiled SVN 759 on Fedora 29 x86_64 and Ryzen 5 2600 CPU, as well as on another Fedora 29 x86_64 system with i7-2720QM CPU. Let me know if I can provide any further information.

Thanks for posting this. I just tried it myself and indeed, it is running at half-speed. I'm not sure why. Either we changed something with the frame timing code that broke Star Wars or a necessary patch was removed from Games.xml. I'll try to investigate to find which SVN commit broke it...

[Bart]

Found the problem. I had removed a bunch of ROM patches because I noticed the game appeared to boot and run just fine. I didn't realize that they affected the game's speed. This is also why only one ROM set ever ran at full speed -- the equivalent patches never existed for the other game revisions. Until we commit these to the code base, you can edit Config/Games.xml yourself, find the "swtrilgy" section, and replace the current patches (there should just be a single one) with:

Code: Select all

      <patches>
        <patch region="crom" bits="32" offset="0xf0e48" value="0x60000000" />
        <patch region="crom" bits="32" offset="0x043dc" value="0x48000090" /> <!-- related to joystick feedback -->
        <patch region="crom" bits="32" offset="0x029a0" value="0x60000000" /> <!-- skip force feedback setup? -->
        <patch region="crom" bits="32" offset="0x02a0c" value="0x60000000" />
        <!-- Additional patches from MAME for test menu -->
        <patch region="crom" bits="32" offset="0xf776c" value="0x60000000" /> <!-- unemulated JTAG stuff -->
        <patch region="crom" bits="32" offset="0xf7770" value="0x60000000" /> <!-- "" -->
        <patch region="crom" bits="32" offset="0xf7774" value="0x60000000" /> <!-- "" -->
      </patches>

Thank you, editing games.xml as per your instructions fixed the slow motion issue Happy new year!

[lancethrust]

I’m sorry for this super basic question - but I’m really new to all of this...
Where do I find the Config/Games.xml file where I add this code to?
I’m running just ONE game on my system - Star Wars Trilogy Rev A and it goes slow motion at the trench scene (best part of course) id love to get this ONE game working right.
Thank you!

[belegdol]

The fix has been incorporated into the SVN, you should not need to edit anything.
