23// Glide64 - Glide Plugin for Nintendo 64 emulators
24// Project started on December 29th, 2001
25//
26// Authors:
27// Dave2001, original author, founded the project in 2001, left it in 2002
28// Gugaman, joined the project in 2002, left it in 2002
29// Sergey 'Gonetz' Lipski, joined the project in 2002, main author since fall of 2002
30// Hiroshi 'KoolSmoky' Morii, joined the project in 2007
31//
32//****************************************************************
33//
34// To modify Glide64:
35// * 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.
36// * 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.
