| 24 | // Project started on December 29th, 2001 |

| 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 |

| 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. |

| 47 | Notes: |
| 48 | ------ |
| 49 | |
| 50 | Setting the approprate bits in the MI_INTR_REG and calling CheckInterrupts which |
| 51 | are both passed to the DLL in InitiateGFX will generate an Interrupt from with in |
| 52 | the plugin. |
| 53 | |
| 54 | The Setting of the RSP flags and generating an SP interrupt should not be done in |
| 55 | the plugin |
