MALA with MAME .123 64bit really slow, 32bit fine

[rooter]

I compiled my own 64bit version of MAME and I'm having problems.  When I tried running it, everything was incredibly slow.  It was completely unplayable.  It took the emulator about 5 seconds to respond to any key press and I was getting about a frame per second.  I thought I might have screwed up the compile somehow, so I downloaded the official binaries and had the same problem.  I'm running 64bit Vista with a 2.8ghz Intel dual core chip with 4gigs of ram.  The 32bit version of MAME runs fine.  Does anyone have any ideas what might be causing this problem?

Did you accidentally compile it with the Intel Core2Duo optimizations in place?  If that is the case then it will run horribly on an AMD based system.

[rooter]

Almost definitely not.  Would the default distribution have done that?  You would think they would have two versions of the executables on mamedev.org if that was the case.

I've got the stupid question of the day.you sure you have a 64bit os? If you dont, you wont be able to run 64bit programs. Vista 64bit and xp 64 will work, but just because your processor is 64bit, that doesn't mean that you can run 64bit programs. Sorry to post a duuuhh question, but this may be your issue. Also make sure that you get a bin that is optimized for vista, I don't think they all are.

I don't know much about vista, but can you run the executable in compatibility mode?

*edit - missed part of the question

If he didn't have a 64-bit OS he wouldn't even be able to get the program to run.  A 64-bit program won't even load on a 32-bit OS.  You'd immediately get an error message when you try to run the program.

Okay.  So now you have an Intel CPU in there?  Just checking to see if you still have the same problems.  I only ask because I have a 64-bit build of MAME and I'm having no problem running it on a Windows Vista Home Premium 64-bit OS with an Intel 2.5 GHz Core2Duo CPU.

Yeah, that was a bone head move on my part.  It is a Pentium 920 D.  I confused my desktop pc with my arcade machine.  I've swapped a lot of parts between them, so it was an understandable mistake I guess.

I didn't optimize my compile for any certain chip set though, so I don't know the problem. Should I try choosing a specific chip set?  I'm assuming the binaries at mamedev.org aren't compiled for a specific processor and would work in either case.

I would kill to just copy someone's known working Intel build with working highscores, but I know that is frowned upon.

My stupid, good point

Thanks to Headkaze's new program, I think I have made some progress here.  I was able to compile MAMEUI64 and it works great.  I guess this means that the problem is somewhere with MALA.  If I just run MAMEUI64 I have no problems whatsoever.  When I run MALA and use any of the three 64bit builds mentioned in this thread, I have major slowdown issues.  If I run MALA with a 32bit version of MAME, I have no problems.  Has anyone gotten MALA to work with a 64bit version of MAME?  Or any other customizable frontend for that matter?  I really don't want to switch frontends, but I would be willing to do so to switch over to 64 bit.  The only real requirement that I would have is that the frontend needs to support my LEDWiz.

I am running Mala and Mame 123 on Vista 64 Premium with no issues other than slowdown when attract vids are enabled.  This is not an issue in Vista 32 - SP1 for Vista 64 is coming out any day and supposedly has marked perfomrance increases - we'll see if the SP helps.  Other than the attract vid issue, Mala and LedBlinky run great (I'm running Blinky 3.6 beta which solves a speech threading issue in 64 bit O/S).

I'm feeling your pain - I just compiled 123.u5 64 bit Mame (optimized for Core 2 Quad 6600 and running Vista 64 Premium) and launching from Mala is unplayable because of the framerate slowdown . 

I can launch from command line no problems and it runs great.  Mala seems to only play nice with 32 bit versions unless I am missing something in the Mame setup/config that would address this issue.

Perhaps Loadman or someone else has a suggestion?

It's related to the keyhook.
MAME runs fine without any key input for me (I use ultrastiks), but somewhat stops completely for about half a second as soon as I press something on my keyboard.

[joebells]

I wonder if x64 mame has some kind of input issue as I suffer from an eip error when I run x64 mame with a controller turned on. When its on and I'm running mame it acts very slow when trying to assign keys in the menu also. I wonder if some of you might be getting that eip error also. Try running a game from the command line when you exit it'll show it.

I have the same problem. Is their a fix or some kind of workaround yet?

Not yet.  The hope is that its being worked on, fueled by non-commitive comments by Loadman  =D

Just making another post here to let you all know deleting MaLaKeyHook.dll from your MaLa folder will solve the performance issues running it with Mame64. Loadman thought it might work so I tested it on my XP 64 machine and indeed it did solve the problem. Good work loadman your already making progress!

Thanks for testing it on your Commodore 64    I mean 64 bit OS
