mame version running crusin usa 20fps on pentium 4 2.4ghz...
NickG:
I tried Cruisin Usa in MAME Plus! Plus! 0.119 and pure MAME 0.119 and I got 100% in both versions during the attract mode lap. I was getting 83-91% in MAME Plus! Plus! 0.117 and pure MAME 0.118. I still only get 30% in Gauntlet Legends in both MAME and MAME Plus! Plus!. I would like to reiterate that these games do not utilize the plug-ins. As a user, you can tell - right click on the the properties for those particular games and the PSX plugins section of the configuration is missing, so you can't even be enabling them for those games anyway.
The real reason for the better performance is in the source code change for midvunit.c in the 0.119 release. Quoted here is the relative paragraph from the whatsnew.txt in MAME 0.119:
"Added intelligence around the UPDATE_HAS_NOT_CHANGED flag, which is
returned from VIDEO_UPDATE. If all screens in the game return
UPDATE_HAS_NOT_CHANGED, then that frame is effectively skipped (up
to 3 frames in a row) in terms of throttling. This allows games that
render every other frame to not throttle during their "off frames".
Updated the midvunit driver to return UPDATE_HAS_NOT_CHANGED. You
should see an improvement in framerate with throttling enabled for
these games. Note that this only kicks in if frameskip is set to 0.

thanks for the heads up on 0.119 and cruisin, robot8319 :)

I think you should be getting much more than 3 FPS on a 2.4 ghz P4 with regular Mame. I am getting 45 FPS in game with a 3.2 ghz P4 with the I686 optimized version of Mame v0.119, and that's with onboard video. Make sure you don't have autoframeskip turned on as it makes Cruisn run worse.

Okay, I think I'm about to reveal that I'm a complete mame n00b.... I thought the i686 optimized version of MAME was only for Pentium Pro's? My cab is running on Pentium 4 2.4GHz. Should I be running regular mame or the i686 version? Please elaborate!

Nick,
What CPU does your computer have?
Cakemeister:
R. Belmont, one of the MAME developers, thinks MAME plus plus is an "abomination", and has caused him to stop working on his Zinc emulator.
I wonder what Saint's position is on builds of MAME such as MAME plus plus which do not release all source code and therefore are against the MAME license.

It's a C2D E6600; stepping 6; revision B2 at stock speeds. It's on a MSI 975x platinum with 2 GB of RAM @ 1:1 ratio (FSB:DRAM) and default latencies 5-5-5-something.)
I am surprised thats all your 3.2GHz P4 is giving you; I was getting something like 55-57 FPS - IIRC - with my old mobile AMD64 4000+ (single core @2.6GHz) - I don't remember what release of MAME that was. I may have had the throttle option turned off with the AMD64, though.
