I had to reinstall windows on my arcade machine. After reinstalling the Ultimarc AVGA drivers, I haven't been able to find the D9200 tweak utility to get high resolutions to display non-interlaced.
Andy has apparently replaced that tool on his website with a newer version that doesn't work on my Betson Imperial at 800x600.
If anyone has the old version handy (likely named d9200.zip) I would really appreciate the help. I've searched high and low, and I can't find it anywhere.
Update:
I contacted Andy directly, and he sent me the old file via email. I think he's working on the new utility to figure out why it didn't work on the Betson.
