Yes there are no changes for the mist anyway, well except un-breaking it. I guess the turbo freezer breakpoints could be wired up if anyone wants to use them?

P.S. Thanks to slingshot for the heads up I broke it, along with even which svn revision.

For the mcc guys I implemented support for the torrid joypad, with start, select, option, reset and menus mapped to buttons. This is still in the main core firmware. Note that this is not used on the mister since it has a common menu handling and usb setup. I just mention it since it has been done e...

The upstream version has atari800mode (flag in vhdl) for 400/800 hardware.

The intro music plays fine though from the atx version. In-game I only have 'hitting' sounds, is that normal?

Edit: I'm testing on EclaireXL, but the mister is a port so should be the same.

The 'correct' palette is a matter of controversy! I used the default palette from Altirra for the RGB modes, from a few versions ago. For composite modes (on mcctv and EclaireXL) I use 24 degrees on ntsc and 22.5 degrees in pal. That gives the correct colours for the star raiders shields and still h...

Fixed the drive issue: http://www.64kib.com/autobuild/20190719/ 20190719: Bug fix release to allow using drives other than 1! Threw in a feature: vertical blank only turbo, press fire on cpu speed menu. This allows some display timing sensitive software to run faster, though of course is much slower...

I give up. I renamed "576kcompy_PAL_VGA" to "settings". And copy it into a ROM folder "atari800/rom". Nothing changes. It still does not work. I think I will wait for it mistification version. If the hotkeys don't work try one of these ones, all those ones were composite sync since that is my setup...

I fixed the drive thing, in the firmware I had a 0 where there should be the drive number - ooops! I'll rebuild fairly soon.

No updates for a bit, broke my usb blaster cable and need to order one. + summer hols. Regarding issues: Drives: I did rewrite the menu so it’s possible. I’ll test and see what is wrong. Ntsc/cs on 5200: I suggest using the non-cs one, I just added cs for myself. I need composite sync for rgb 15khz ...

Which video mode?

I put up a new build here: http://www.64kib.com/autobuild/20190713/ changes: 20190713: 800xl: mist/mcc216/mcctv Profile support using sd card. Profiles had been implemented only for eclairexl/chameleon using in-built flash memory. Put sdflash.bin provided here in the rom folder. This can be used ins...

I can confirm profiles are not implemented on the mist. The video/memory/system settings can be saved though, but just one set.

Interesting about the cartridges, perhaps I need to reset some of the cartridge logic when a new cartridge is inserted.

rittwage wrote:Is there not an 800 15KHz version anymore (RGB)? I saw that variation in the 5200 version, but the 800 versions only say VGA.

It can be selected in the menu with the hotkeys.

I should have removed the _VGA.

Do you have any idea how to handle system profiles?

On systems with flash I read/store the os roms + settings to flash (4 copies). I just added a big file on mcctv to simulate the same thing. I was thinking of doing that with the mist but am not sure how that fits in with the mistification.

Great thanks, will try that over the weekend or early next week.

Many thanks for the osd + menu + ypbpr patch, really appreciated.

I also have (Atari specific) svideo/composite output, though they are written for an 8 bit dac, not sure how good it’ll be with fewer bits.
See svideo_gtia in the EclaireXL folder.

You need to ‘apply settings’ for video. I’ve already got the pll reconfig working on mcctv, I was planning to share the component. If you already have a good one could you point me to it please? Then I’ll use the better one. I can cut down firmware to allow mistification. Just let me know what you n...

Please send me any feedback, positive as well as ‘this is broken’ :D I’m adding ‘proper’ pal/ntsc switching now. It’s more important on platforms with composite and/or svideo output than mist though. Still it means I can only have a single core for mist. Then I’ll fix the multiple profile support fo...

Most of the good stuff has been ported both ways anyway.

For 0 delay fans, I had success with the synced plls option discussed earlier in the thread. For the Atari 800 core on my own cyclone V board. The original pal core runs at 49.86Hz, so I overclocked it to exactly 50Hz. So 0.28% faster, but no lag. The fractional plls are very accurate, ok perhaps th...

Yes, cycle exact 68k and ST core custom chips. That would be incredible. I hope this makes it to the top of your project list.

Re the 800XL core. I did some work before with a similar platform - the SOCkit board. In that case I used purely block ram for the 800XL itself and I replaced the internal ZPU firmware by a linux version running on the ARM side. It communicated with the core using an avalon slave interface. I never ...

Cool. Many thanks. Will give this a try.

Did you keep a list of things that didn't work, that could be interesting...

Great idea! How flexible have you found your TV to be with component? I mean in terms of exact standard timing CEA modes? With my TVs HDMI port I find the timing needs to be really exact to the standard. Which is ok, but requires minor over/underlocking of the core to 50Hz/60Hz exactly. Other option...

Wow, exciting. I hope he makes it public so it can be ported. I'm particularly interested in his 65816 work for use in the Atari XL core. There are now a couple of others but from what he says this looks more complete.
