| 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 |

| 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. |
