| 18 | 18 | * Switch to tilemap system |
| 19 | * Add IntelliVoice Support |
| 20 | * Note from kevtris about IntelliVoice Hookup: |
| 21 | <kevtris> the intv uses a special chip |
| 22 | <kevtris> called the SPB640 |
| 23 | <kevtris> it is really cool and lame at the same time |
| 24 | <kevtris> it holds 64 10 bit words, which it simply serializes and sends to the SP0256 |
| 25 | <kevtris> the SP0256-012 just blindly jumps to 02000h or something when you try to play one of the samples |
| 26 | <kevtris> the SPB640 sits at 2000h and when it sees that address come up, it will send out the 640 bits to the '256 |
| 27 | <kevtris> this means you cannot use any gotos/gosubs in your speech data, but that is OK |
| 28 | <kevtris> it's just a single serial stream. the intv simply watches the buffer state and refills it periodically. there's enough buffer to keep it full for 1 frame |
| 29 | <kevtris> that's about it |
| 30 | <kevtris> the samples are stored in the game ROMs, and are easy to extract |
