10:05 PM Bug #48 (Closed): CORE13 - Veronica BASIC not working

Closed. Working fine with my Veronica clone and no feedback received from tester. foft

10:02 PM Feature #3 (New): High resolution antic support

Paused until anyone uses it. If it starts getting used I might fix the offsets... foft

10:01 PM Bug #25 (New): F10 Hard Reset Ignore inserted cartridge (Core v7)

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. foft

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 ... foft

09:58 PM Feature #68 (Closed): Implement stock Atari 800 mode

Great! Going to close this until I decide to add 2 bus support or you find a bug in it:-)

That worked! I tested both variants of Archon, MULE and One on One and they all loaded just fine. Great job! Now I ju... Farb

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:

10:54 AM Feature #68: Implement stock Atari 800 mode

I guess it’s checking c000-cfff then?
I’ll try adding a floating data bus... foft

07:55 AM Feature #68: Implement stock Atari 800 mode

The OS ROM I'm using has a CRC of 0e86d61d. Farb

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... foft

I’d better wire up the atx code so I can try it myself:) foft

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... foft

09:39 PM Feature #68: Implement stock Atari 800 mode

This is fantastic progress!! Farb

09:23 PM Feature #68: Implement stock Atari 800 mode

That worked... Now for that horrible beep on reset. foft

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... foft

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... foft

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... foft

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... foft

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. foft

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... foft

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... foft

I know of one game that relies on it -- Coleco's Wargames. Phaeron and I chatted about this a while back because I co... Farb

@farb - do you know if the protection ever needs the floating data bus? For now I've set 0xc000 to either 0xff in <52... foft

08:57 PM Feature #68 (In Progress): Implement stock Atari 800 mode

Added Atari800 mode.

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. foft
