// 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.
