- 10:05 PM Bug #48 (Closed): CORE13 - Veronica BASIC not working
- Closed. Working fine with my Veronica clone and no feedback received from tester.
- 10:02 PM Feature #3 (New): High resolution antic support

- 10:01 PM Bug #64 (Closed): Pokey pdm timing incorrect
- Found the issue when doing the pokeymax work - I'd lost some changes by accident.
- 10:00 PM Feature #72 (Closed): Implement stock Atari 400 mode
- OK, so for all intents and purposes I think its the same. At least until we add the split bus for the 800... I added ...
- 09:58 PM Feature #68 (Closed): Implement stock Atari 800 mode

I mean the profiles. The... - 09:14 PM Feature #68: Implement stock Atari 800 mode
- That worked! I tested both variants of Archon, MULE and One on One and they all loaded just fine. Great job! Now I ju...
- 08:16 PM Feature #68: Implement stock Atari 800 mode
- OK, I built v27. This has a single floating data bus. I also updated the os rom in slot 4 to this one:
10 KB 0x0e86... - 05:23 PM Feature #68: Implement stock Atari 800 mode
- From phaeron:
Altirra implements a single floating bus by default for 800 and XE hardware profiles and has an opt-... - 05:20 PM Feature #68: Implement stock Atari 800 mode
- From Ijor on the protection details:
IIRC it expects to be variable, non constant. The 800 doesn't have pullups on... - 10:54 AM Feature #68: Implement stock Atari 800 mode
- I guess it’s checking c000-cfff then?
I’ll try adding a floating data bus... - 07:55 AM Feature #68: Implement stock Atari 800 mode
- The OS ROM I'm using has a CRC of 0e86d61d.
- 07:47 AM Feature #68: Implement stock Atari 800 mode
- Did you load the original OS B or use the one off the jic? I think the one I included on the jic is patched. I should...
- 07:46 AM Feature #68: Implement stock Atari 800 mode
- I’d better wire up the atx code so I can try it myself:)
- 08:28 PM Core v27
- Small update to try to get some atx stuff working...
Single floating data bus: atari800 non-present ram and D1/D5/...

- 10:48 PM Feature #68: Implement stock Atari 800 mode
- I‘d personally would love to see this get as close as possible to a real Atari 800 but obviously I’m not doing all th...
- 09:48 PM Feature #68: Implement stock Atari 800 mode
- Fixed the beep on reset. Will build as v26. Not sure whether floating data bus if worth it. Looks like it wasn't even...
- 09:39 PM Feature #68: Implement stock Atari 800 mode
- This is fantastic progress!!
- 09:23 PM Feature #68: Implement stock Atari 800 mode
- That worked... Now for that horrible beep on reset.
- 09:17 PM Feature #68: Implement stock Atari 800 mode
- This is due to a brk being hit when it jumps to the cart to initialize it. Making the bus 0xff when no ram present wh...
- 08:32 PM Feature #68: Implement stock Atari 800 mode
- Got signal tap on it. Gets part way through booting then hangs at address 000c. This is after memory detection itself...
- 10:30 PM Core v26
- Atari800 mode fixes:
* Made no ram return 0xff, fixes 16k/32k boot since they were detecting a cartridge then crashi...

- 08:41 AM Feature #68: Implement stock Atari 800 mode
- Tried the salt xex. If I boot it on 48k, then change ram to 16k/32k it returns the expected results. i.e. ram test pa...
07/27/2018
- 10:25 PM Core v25
- A few fixes in pokey from when I was working on pokeymax.
Also the start of Atari 800 support. Some bugs still, be... - 10:12 PM Feature #68: Implement stock Atari 800 mode
- Built as v25 anyway in case anyone wants to play, but definitely more to do on this...
- 09:48 PM Feature #68: Implement stock Atari 800 mode
- Squashed several bugs, but struggling with 16k and 32k mode for some reason, not booting.

- 02:17 PM Feature #68: Implement stock Atari 800 mode
- This is great news! I look forward to testing it :-)
07/25/2018
- 10:06 PM Feature #68: Implement stock Atari 800 mode
- Got it booting again after a few small bug fixes.
Some reset issues on the 800... and it fails the XL banking acid... - 09:27 PM Feature #68: Implement stock Atari 800 mode
- OK, that sounds ... fun! It won't be expensive to add support for but I need to think about it.
For now I just wan... - 09:11 PM Feature #68: Implement stock Atari 800 mode
- I know of one game that relies on it -- Coleco's Wargames. Phaeron and I chatted about this a while back because I co...
- 09:03 PM Feature #68: Implement stock Atari 800 mode

- 08:57 PM Feature #68 (In Progress): Implement stock Atari 800 mode
- Added Atari800 mode.
Ram selection dialog changed to system. Pressing fire toggles 800/xl/xe.

- 10:07 PM Feature #73: Implement ATX disk image support
- Pleased to see it looks pretty simple, so we should be able to plug this in without too much pain.
- 10:05 PM Feature #73: Implement ATX disk image support
- Ah, that makes more sense. The loadAtxSector seemed to be missing all the timing I was expecting, then I saw the phan...

- What is the basic interface?
If I receive a command packet, can I send it to the atx handling code and it returns ... - 08:29 AM Feature #73: Implement ATX disk image support
- The SDrive Max project has ATX disk images working including many forms of timing-based protection. The code is writt...

- 10:06 PM Feature #72: Implement stock Atari 400 mode
- Most of this is probably not relevant here, but my understanding of the differences are:
1. Membrane vs. full-stro... - 09:10 PM Feature #72: Implement stock Atari 400 mode
- Are there any differences from the Atari800 mode? I guess 2 joystick ports. I guess also allowing less than 48K of ra...
- 08:20 AM Feature #72 (Closed): Implement stock Atari 400 mode
- There are certain titles that require OS-A to run (Megalegs, Ghost Hunter). It would be nice to have a "stock Atari 4...
