Re: [Atari 800 core] Mark Watson's new site

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.

Re: Atari 800 Core - keyboard free operation - Start, Select, Option on Joystick

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...

Re: World Karate Championship Atari800

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.

Re: World Karate Championship Atari800

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...

Re: [Atari 800 core] Mark Watson's new site

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.

It can be selected in the menu with the hotkeys.

Re: [Atari 800 core] Mark Watson's new site

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.

Re: [Atari 800 core] Mark Watson's new site

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.

Re: [Atari 800 core] Mark Watson's new site

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...

Re: [Atari 800 core] Mark Watson's new site

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...

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...

Re the 800XL core. I did some work before with a similar platform - the SOCkit board.

It communicated with the core using an avalon slave interface. I never ...

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.
