- 09:45 PM Bug #33 (Closed): Wizard of Wor
- I modeled this by adding a 1 cycle delay on sel9bitpoly going high. The game then works!
- 09:04 PM Bug #33: Wizard of Wor
- The high bit of audctl is sel9bitpoly. In the original chip is is delayed and then combined with itself. So I need a ...
- 08:44 PM Bug #33: Wizard of Wor

- With 8f for only ... 6 cycles
- 07:57 PM Bug #33: Wizard of Wor
- It writes 8f and 00 often to audctl. This switches the shift register from 17 bit to 9 bit and back. Could there be s...

So, the issue seems to be with pokey. OK, getting closer! Will check w... - 09:25 PM Bug #33: Wizard of Wor
- I'm trying it on my 600XL. I'm getting similar crashes, when running with PokeyMAX. So could be a Pokey bug, or incom...
- 08:10 PM Bug #33: Wizard of Wor
- Crashes in the same way with T65, so... I guess its not a cpu bug!
- 08:04 PM Bug #33: Wizard of Wor

- 08:01 AM Bug #33: Wizard of Wor
- I have a feeling I did a cpu patch that I wasn’t certain about to fix the Irq blocking nmi acid test. I expect that i...

- 09:03 PM Bug #33: Wizard of Wor
- Planning to shift the dli so it does not overlap, to see if that fixes it.
- 08:29 PM Bug #33: Wizard of Wor
- 9c0c: pla on 2nd dli is when 3rd dli fires. This could be shifted by a few cycles on 'events', which could be when it...
- 08:16 PM Bug #33: Wizard of Wor

Second dli, wsync, change charset
Third dli, was ente... - 08:00 PM Bug #33: Wizard of Wor
