09:30 PM Bug #60 (Closed): Prozac dreams large logo flickers: OK, that worked but broke an acid test. Now have a solution that works without breaking the acid test... Closing:-) foft
08:42 PM Bug #60: Prozac dreams large logo flickers: Nasty edge case around dma disabling for the last few cycles of the scanline and cpu cycle completion timing, combine... foft
08:10 PM Bug #60: Prozac dreams large logo flickers: There is an extra dma fetch at colour clock 0, investigating what is going on... foft
07:03 AM Bug #75: USB keyboard stops functioning after idle period: Well I just received Millionaire on disk so I can give it a go and see if I have the same issue. My keyboard definite... foft

09:36 PM Bug #60: Prozac dreams large logo flickers: Wired up the pbi enable/disable to the menu, so I can turn it on/off and see the result on the frozen screen. Enough... foft
09:32 PM Bug #60: Prozac dreams large logo flickers: Its a plain antic 4 display. Seems to be a kernel that moves pmgs around and sets colours also changes character set.... foft
10:47 AM Bug #75: USB keyboard stops functioning after idle period: Yes, the core is still running because we were hearing music play. The game we were playing didn't use a joystick so ... Farb

09:02 PM Bug #60: Prozac dreams large logo flickers: What do I know so far...
pbi disabled -> works
pbi enabled -> breaks
Tried instead by delaying the cpu enable 20... foft

07:25 PM Bug #75: USB keyboard stops functioning after idle period: Unlikely to be the ribbon, though if its iffy you should replace it. I say that because while the joysticks are conne... foft
02:41 PM Bug #75: USB keyboard stops functioning after idle period: I have seen it happen a few times using the same USB keyboard (which was also the same keyboard I used on the MiST an... Farb
10:27 AM Bug #75: USB keyboard stops functioning after idle period: Two potential problems:
1) max number of devices was decreased in v28, should have no impact but it was a change.
2... foft

10:16 PM Bug #75 (Closed): USB keyboard stops functioning after idle period: I have noticed in the last few core builds (up to and including v29) that if the USB keyboard is idle for too long, i... Farb

02:59 PM Bug #60: Prozac dreams large logo flickers: This one annoys me, since the cycle position change should not break anything in antic. Should be easy to make a core... foft
02:58 PM Feature #32: option to connect the original ATARI XL keyboard to ExclairXL: One from back in the day...

On pokeymax I'm using an i2c to parallel ... foft
02:51 PM Bug #52 (Closed): Atari Control Picture: Fixed by giving gtia modes priority over the high-res mode. This fixes the acp while acid still passes.
Still awar... foft

09:41 PM Bug #52: Atari Control Picture: So this is mode 8 to mode 9. 'clean transition after 4 colour clocks'.
The Eclaire takes 5 colour clocks here and ... foft
09:38 PM Bug #52: Atari Control Picture: For reference, the relevant passage from the Altirra hardware reference manual:
GTIA mode changes
A change to bits ... foft
09:35 PM Bug #52: Atari Control Picture: I fixed this by adjusting the delay on turning off the highres flag when switching into gtia mode. However it broke t... foft

10:06 PM Bug #52 (In Progress): Atari Control Picture: Managed to capture in the logic analyzer with lots of info... Now just need to understand it then I can fix! foft
07:15 PM Bug #38 (Closed): Numen crashes on v9: foft
07:12 PM Feature #73 (Closed): Implement ATX disk image support: Closing this, since the core support is present. Of course we can raise new tickets for improvements/fixes or e.g. 10... foft

09:55 PM Bug #74 (Closed): Mounted disks don't always load: Closing as I think this is fixed in v29. Reopen if problems still seen! foft

10:08 PM Bug #74: Mounted disks don't always load: In the end I chose to use the SIO clock for receiving command packets. I also count the rate. Then I reply using the ... foft

11:48 PM Bug #74: Mounted disks don't always load: Except I need to send start bit from zpu to start that clock. Probably a fairly simple state machine change, but gett... foft
10:53 PM Bug #74: Mounted disks don't always load: On second thoughts, why guess when I know. Pokey is already outputting the serial input anyway (even in input mode, s... foft

09:29 PM Bug #74: Mounted disks don't always load: Implemented using sio clock out as the zpu clock input. Should mean it can listen to whatever speed. Though of course... foft

09:38 PM Bug #74: Mounted disks don't always load: I'd added a 2ms delay temporarily to stop some fast/slow flip flopping. That actually breaks USB keyboard when in tha... foft
