Ghosting/Lag with IPAC Controls

Hi Andy,

Sorry I meant to come back to this last week... I actually figured out my issue.

First off, to answer your question, I have the IPAC w/USB cable but had purchased a USB/PS2 adapter and that's how I had it hooked up - IPAC to PS2 (via adapter).  I had to reflash using the PS2 option but it seemed to work just fine.  I did this since some suggestions indicated it could be usb related.

Now to the issue at hand... I did as you suggested and ran Keytest as well as MAME in the background (difficult to do btw since MAMEWAH was taking away my mouse pointer, etc!).  Once I did this I noticed that keytest was showing several keys 'locked' down.  In other words, it showed a key pressed that never was released.

To test better, I closed MAMEWAH and just started MAME32 (story behind that coming up next for reference) and noticed that the same keys were showing continuously pressed.  Then I tried this test again with the IPAC disconnected and using my PS2 keyboard as the controls.  Same problem!  Now I knew I was on to something.

BACKGROUND story:  Before this whole incident started I had always had the dos version of MAME as my exe in MAMEWAH.  However, after not having played in quite some time I fired it up and noticed that several roms were no longer loading using dos MAME.  As a quick fix I changed the exe to MAME32 which allowed all my roms to work but apparently this was what caused my keypresses to 'stick'.

So, I've since changed the exe that MAMEWAH is using back to the dos version of MAME.  No more lagging, ghosting, keypress issues!  Of course it still means some roms won't load but I'm hoping to research and resolve that separately.

I can't thank you enough for your responses and attention to my issue.  I'm a fan of your product and have a buddy that started this project at the same time I did but has left his unfinished cab as a shell.  He'll be another IPAC fan soon (once I can convince him to reboot this hobby!)...

Thanks again!
