  26 Our strategy here is like so:
  27 Look at the files in the directory pointed to by ROMPath.
  28 For each file in the directory, take the CRC32 of it and compare it to the CRC
  29 in the romList[]. If there's a match, put it in a list and note it's index value
  30 in romList for future reference.
  31
  32 When constructing the list, use the index to pull up an image of the cart and
  33 put that in the list. User picks from a graphical image of the cart.
  34
  35 Ideally, the label will go into the archive along with the ROM image, but that's
  36 for the future...
  37 Maybe box art, screenshots will go as well...
  38
  39 I'm thinking compatibility info should be displayed as well... Just to stop the
  40 inevitable stupid questions from people too lazy to do basic research for themselves.
  41
  42
  43 Data strategy:
  44
  45 - Should keep a QImage of the blank cart with blank label
  46 - Should keep a QImage of the blank cart? (For overpainting the ROMs label)
  47 - Should we have a special Alpine image? Floppy image (for COF/ABS)?
  48
  49 - Need some way of keeping track of cart size and compatibility info
  50   [compat info needs to be BAD DUMP or % of what works]
  51 - Need to properly scale the thumbnails images in the list
