| 28 | * This software provides an algorithm that emulates the protection scheme of |
| 29 | * N64 PIF/CIC-NUS-6105, by determining the proper response to each challenge. |
| 30 | * It was synthesized after a careful, exhaustive and detailed analysis of the |
| 31 | * challenge/response pairs stored in the 'pif2.dat' file from Project 64. |
| 32 | * These challenge/response pairs were the only resource used during this |
| 33 | * project. There was no kind of physical access to N64 hardware. |
| 34 | * |
| 35 | * This project would have never been possible without the contribuitions of |
| 36 | * the following individuals and organizations: |
| 37 | * |
| 38 | * - Oman: For being at the right place at the right time and being brave |
| 39 | * enough to pay a personal price so we could understand in a much deeper |
| 40 | * way how this magical console really works. We owe you so much. |
| 41 | * |
| 42 | * - Jovis: For all the positive energy and impressive hacking spirit that you |
| 43 | * shared with the N64 community. You were absolutely instrumental in |
| 44 | * several key events that shaped the N64 community in the last 14 years. |
| 45 | * Even if you're not physically with us anymore, your heritage, your |
| 46 | * knowledge and your attitude will never be forgotten. |
| 47 | * |
| 48 | * 'The candle that burns twice as bright burns half as long.' |
| 49 | * |
| 50 | * - LaC: For the endless contributions that you've given to the N64 community |
| 51 | * since the early days, when N64 was the next big thing. I've always |
| 52 | * admired the deep knowledge that you've gathered about the most little |
| 53 | * hardware details. Recently, you challanged us to find a small and |
| 54 | * concise algorithm that would emulate the behaviour of CIC-NUS-6105 |
| 55 | * challenge/response protection scheme and here is the final result. |
| 56 | * LaC, Oman and Jovis were definitly the dream team of N64 reversing in |
| 57 | * the late 90's. Without your contributions, we would be much poorer. |
| 58 | * |
| 59 | * - marshall: For keeping the N64 scene alive during the last decade, when |
| 60 | * most people lost interest and moved along to different projects. You |
| 61 | * are the force that has been keeping us all together in the later |
| 62 | * years. When almost nobody cared about N64 anymore, you were always |
| 63 | * there, spreading the word, developing in the console, and lately, |
| 64 | * making impressive advances on the hardware side. I wish the best |
| 65 | * success to your new 64drive project. |
| 66 | * |
| 67 | * - hcs: For your contributions to the better understanding of the inner |
| 68 | * workings of the Reality Co-Processor (RCP). Your skills have impressed |
| 69 | * me for a long time now. And without your precious help by sharing your |
| 70 | * kownledge, I would have never understood the immense importance of |
| 71 | * Oman, Jovis and LaC achievements. Thank you ! |
| 72 | * |
| 73 | * - Azimer & Tooie: For sharing with the N64 community your findings about the |
| 74 | * challenge/response pair used in 'Jet Force Gemini' and the 267 |
| 75 | * challenge/response pairs used in 'Banjo Tooie', all stored in the |
| 76 | * 'pif2.dat' file of Project 64. They were instrumental to the final |
| 77 | * success of this endeavour. |
| 78 | * |
| 79 | * - Silicon Graphics, Inc. (SGI): For creating MIPS R4000, MIPS R4300 and |
| 80 | * Reality Co-Processor (RCP). You were the ultimate dream creator during |
| 81 | * the late 80's and early 90's. A very special word of gratitude goes to |
| 82 | * the two teams that during those years created RCP and MIPS R4300. They |
| 83 | * were technological breakthroughs back then. |
| 84 | * |
| 85 | * On a personal note, I would like to show my deepest gratitude to _Bijou_, |
| 86 | * for being always a source of endless hope and inspiration. |
