  // Glide64 - Glide Plugin for Nintendo 64 emulators
  // Project started on December 29th, 2001

  // Authors:
  // Dave2001, original author, founded the project in 2001, left it in 2002
  // Gugaman, joined the project in 2002, left it in 2002
  // Sergey 'Gonetz' Lipski, joined the project in 2002, main author since fall of 2002

  //
  // To modify Glide64:
  // * Write your name and (optional)email, commented by your work, so I know who did it, and so that you can find which parts you modified when it comes time to send it to me.
  // * Do NOT send me the whole project or file that you modified.  Take out your modified code sections, and tell me where to put them.  If people sent the whole thing, I would have many different versions, but no idea how to combine them all.
