I've decided to get back in the hobby again. I have converted about 6 arcade cabinets into MAME cabinets in the past but have not done a full project in about 5 or so years. All of my machines have used an I-Pac or Opti-Pacs. Are there any new encoders or other technology that you may think I should know about in the last few years? I would love to hear any comments good or bad about what might be on the market. Any help is appreciated. Thanx.
