Ever get the feeling that maybe the Ultimarc stuff and Maximus Arcade just don't play well together?
I did.
In fact my Ipacs didn't play well with Maximus or Mala, just too buggy.
Ditch the Ipacs/Jpacs, and that will solve your problem.
I did.
I just bought the cheapo Chinese encoder off ebay for 20bux.
http://forum.arcadecontrols.com/index.php?topic=113432.0It got rid of all the escape, focus and error issues that I found common with both my early version Ipacs. They were virtually unusable. I've used them for years, but the problems just sort of crept into the Ipacs as they aged or if that has to do with newer Mames or Windows updates or whatever? To be honest I don't care, I'm not the manufacture, it was just wasting all my time trying to fix it.
Also, not sure if the new USB Ipacs have solved or circumvented these issues and would love to hear from those who know or have them installed in their cabinets now with Max or Mala and a current version of Mame. It might be that the USB hookup bypasses these issue?
