   That would be a monumental task -- taking existing video, digitizing it,   
   post processing in a GPU and then redisplaying.  Video games (arcade pieces)   
   were "fitted" to their component parts.  You didn't buy a generic multisync   
   monitor and use it in one of its "modes".  Rather, you designed the hardware   
   to drive the monitor AT it's specified extents.  (Doing otherwise would   
   be wasteful).   
      
   Quantities weren't particularly high (10-20K total production) but the industry   
   didn't have room for slop/margin.  A game *might* have to pay for itself in as   
   little as 90 days (the "90 day wonders" where the market moved on a few months   
   after their release)   
      
   [When was the last time you played Monopoly?  You may still have one tucked   
   in a closet -- they don't take up much room (unlike arcade pieces) -- but   
   it likely has been "tucked" for a long time!  (This, IMO, is the driving   
   force behind *thin* cocktails -- let it act as your kitchen table!]   
      
   John seems to be addressing the folks who either want a "home arcade"   
   (for its novelty) or want to preserve a particular machine (sentimentality)   
   Mame just doesn't cut it on either score.   
      
   [I am still holding onto a Rogo as it had a special place in my heart,   
   though I have gifted all of my other arcade pieces to friends.]
