  1. /**
  2.  * PJM>BK2 Input converter v0.3
  3.  * Author: CoolKirby
  4.  * Language: Java (Comments in English)
  5.  * First created: 9/12/15
  6.  * Last revised: 9/16/15
  7.  * Works with 1 and 2-player PJMs!
  8.  * Works with both DualShock and PSX Controller PJMs! (though most are PSX Controller only)
  9.  * Supports both DualShock and PSX Controller output: use 'convert.pjm' for DS, 'convert_pad.pjm' for PSX Controller
  10.  *
  11.  * Recent Changes: disc 1 instead of -1, Support for native DualShock PJMs, Disc No./Reset/Disc Open/Disc Close, catch and correct most malformed PJMs
