    To add to this question, now that my Sophia has been converted to a standard NTSC palette is there a way to activate the previously provided extra color mode via software?

    Simius has already cleared this up: "The 16 shades is now switchable by bit3 PMCTL ($D01D) (default 0=off)"

    I also think that backplate can be 3d printed.But on other hand iron backplate is more solid, stronger solution.

    Try find lasercutting service near you.Its not very high priced.One meter for 50 cents or so.Try mechanical engineering companies or advertising companies with laser cutter (they are using them for company logos and so).So 1meter will be 10x backplate or so...Personally I have 2 PCs and both have no backplate (for better air circulation) only my MAC has backplate...So for me its OK to have just ports...

    The issue is that lasercutting won't cut it (pun intended :D) for a full-featured backplate as also some intricate bending of the edges has to be done. See the image of the blank backplate in post #513.

    Fellow atarians,

     

    In the latest edition of the (superb) magazine EXCEL #4, they mention Fandal's new game "Spellbinder"

     

    http://excel-retro-mag.co.uk/order-excel-magazine/excel-magazine-4/?v=79cba1185463

     

    Does anyone know when it is going to be released?

     

    Regards,

    Spellbinder will be released with the new issue of the Flop magazine. It should have been out at Atariada 2017 already, but because of certain technical issues, Flop release has been postponed. You can expect it in the near future though.

    I had given this idea some thought too, but was thinking it might be too thin and brittle. I suppose if it was printed thick enough and doesn't obstruct the connectors it probably would be fine. Plus, I guess it's just going to be put in place and left alone for the most part. It probably will be more economical, although a person could drill and cut the holes on the $2.99 metal plate themselves if they wanted to. It's thin enough that it would be able to be cut with a utility knife, and then the circular holes could be drilled. I'd be interested to see what could be done with a 3D printer though.

    If anyone has the skills/tools/friends to drill a metal plate, it could be glued or screwed on to the plastic backplate for more sturdiness and better look. It would surely be much easier to customize a flat metal plate than make an intricately shaped one that would hold there on its own.

    After a long time, finally a song that is not terribly out of tune :-) And really not a bad one. I'd try some shallow and slow vibrato for the lead voice if the frequency resolution allows. Or maybe some portamentos here and there.

    I've seen on a video that default READY prompt is not white but greenish, to show that two colors are now available.

    I would prefer standard white color READY.

    The problem is that the value in COLPF1 (D017/709) is 202, which is just that colour. So blame the Atari engineers that they did not set that to 154, which would correspond to what you actually see on the screen.

    IIRC, Atari800WinPL does not change palette when switching from PAL to NTSC, instead you have to choose the palette manually. So you may be running that emulator in NTSC mode with PAL palette. You can change palette in Altirra manually to PAL colours if you prefer that setting.

    Hi, first I wanted to thank you for the time you spend on Altirra development, which gets so much better with every release. Second, I'd like to ask if there is any chance that Altirra could support adaptive synchronization technology such as Freesync or G-Sync. Running the emulator in PAL mode on a 60Hz display is such a pain... :)

    How are you guys converting the RMT output to .mp3? I'd love to capture both audio and video from an emulator, but Camstudio tried to put too much nonsensical SW on my work PC, so I won't install it.

    You can use WinAMP diskwriter feature together with the ASAP plug-in.

    It's a little bit like the "Infinite Bobs" technique but it wouldn't work in this case since the segments are different and they are finite length snakes.

     

    The problem with doing this on Atari in softsprites is the limitations of how much can be rendered. Doing standard types with background save/restore you'd be looking at an upper limit of about 8-10 of the bigger ones which in the case of this title screen doesn't even cover half of what's going on.

     

    What might be needed is some optimization such as snapping the objects to character boundaries as much as possible.

    On looking closer - it seems these things don't cross over much, so they could probably be drawn without doing save/restore so long as the Z-ordering was done and at that would just mean render the small ones first. But that still mightn't be enough.

     

    Of course, all this thought is assuming we keep 50 FPS and don't use PMGs.

     

    The next course of thought IMO is - could this thing be achieved only using 128 characters. If so and everything was done to character boundaries then it'd be easy although it probably wouldn't look very smooth.

    Unlimited bobs with finite length are actually doable - see MaPa's intro:
