23 | // Glide64 - Glide Plugin for Nintendo 64 emulators (tested mostly with Project64) |
24 | // Project started on December 29th, 2001 |
25 | // |
26 | // To modify Glide64: |
27 | // * 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. |
28 | // * 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. |
