You could try this in your MiSTer.ini... Create a section for each core with it's core name: [corename] refresh_min=59 refresh_max=60 I didn't personally try this, but it might work for you. Only do this for problematic cores. If you want to try them all at once, you could put [arcade] instead of the core name, but be sure not to leave it this way ...

This reminds me a bit of the days of Bitboys Oy / Glaze 3D. A really great product, in theory, that may or may not ever become a real product. It will be interesting to see if it comes to fruition. Personally, I don't see myself needing one because I am more into the more classic stuff and MiSTer meets my needs.

Could you try it with the Black & White mode? I found my other composite adapter and on my TV, it is very dim, but I can see the various colors barely. On my Apple IIc monitor It looks mostly like a bunch of different shades of gray. There may be a hint of color in there, but it is nothing like what it should look like. When selecting Color mo...

[) I provided a list of what color matches the closest for each number 1-14. Did you provide this? I thought this was "handpicked". Oh you're right - it is the list (not the picture of RGB). Maybe we need to have a custom palette option so you can load what you want ... will give it a try at some point That would be cool. Then I could ex...

thorr

if you can create a new RBF using my monitor's color based on the photo for the IIc palette, that would be great! I already did :) Check the attachment in my post above: https://misterfpga.org/viewtopic.php?p=86672#p86672 So that is color matched to my photo? I was asking for two different things so I am not sure what I should be selecting: 1) I p...

It could be the adapter; I think early A.V. adapters had their own clock so they operate at a different frequency than the core. But your might be an earlier model. Anyway - try the build above and hopefully you'll get good colors. I just thought of something and came here to post it. It could be the adapter, lol. I have two of them because S-Vide...

Is this your monitor by any chance? https://oldcrap.org/2019/05/14/apple-iic-monitor/ Also does your IIc have some kind of dongle to connect to the video-port, allowing to plug a "regular" composite jack to it? Either way, it's clear your monitor does not do artifact color ... so we have to generate the color in the core. The reason I am...

thorr

I would call this "Composite Out" once we get it dialed in perfectly since it is only for use with composite output. Just curious, is there a specific reason why you are using colors from the core in composite mode? Could you try it with the Black & White mode? The intended use with Composite video is to set the core in Black & W...

Dang it I just ordered a used Canon EF 100mm f/2.8 Macro lens because I want better close up photos like my phone can do. I will take my photos with that after it arrives and after my company leaves. This will help with my future photos for akeley too.

thorr

Well, I have the answer, it is from my list for the composite output. The colors look much better on my monitor now! I would call this "Composite Out" once we get it dialed in perfectly since it is only for use with composite output. Here is a photo from my phone which is not as good as my previous pictures but will have to do for now sin...

thorr

Thanks! Is the new version for RGB using my photo, or for composite using my list? If it is for RGB I would compare my TV with component to the IIc since the composite might muck up the color, but also will check the IIc monitor for curiosity's sake. The gamma adjustment will be interesting too. The third color and brown are quite different IMO also.

thorr

I was referring to the latest HW design. Personally I would not touch a design that relies on forked cores, because you are dependent on someone else to do the work and maintain the forks. If you feel happy doing this then thats fine too. The HDMI output has been 24 bit from the start and via the dongles a 24 bit Analog signal could be obtained if...

thorr

Thanks for working on this and for your reply. I will work on this when I have more time. I have company coming and will be quite busy for a few weeks preparing and visiting. Having an adjustable palette like the knob would be very cool. In the meantime I still like my actual colors better that are accurate with all the descriptions like light blue...

If it wasn't for your comment, I would never have found Antonio Villena's shop. I'm looking at his MINI IO. It says it has a RGB888 video DAC. Can't find much on the internet about it, how good is it? I like it a lot. If you want 24-bit out the VGA port, you have to download his specific cores for it. It looks great with everything out of the box ...

I[*] new maths-derived //e NTSC palette (1) As a follow up, my guess is the composite hardware in the IIc combined with the hardware in the IIc monitor generates the correct colors. Both may be different than standard composite, but work well together. This might explain why the math-derived ones look wrong, but I have no idea. Also, are the HGR c...

I took pictures of my Apple IIc monitor with my Apple IIc and the various MiSTer palettes and Color 1/2 modes using composite. See them here: https://imgur.com/a/W1YmEtT Here is the better of the two Apple IIc photos rotated to match the above (these are horizontal lines that I image edited to rotate to be vertical): https://i.imgur.com/JbAnNGc.jpe...

I have been trying a few things but havent been successful. I thought of a way to do this. In your MiSTer.ini file, make a section for the core with [corename] and define multiple player_1_controller lines. I actually was the one that requested this feature lol. See the player_4_controller line for what you want probably, and it probably would onl...

thorr

Thanks! When I get a chance, I will hook this up to my Apple IIc monitor with composite and compare with my Apple IIc. I mentioned I will do this in the IIgs thread, but I haven't gotten time yet. It might be a few weeks because I have company coming soon. It will be interesting to try the different palettes to see which is the most correct. Maybe ...

thorr

If your two controllers each have their own encoder, as you suggested, and each encoder is the "same" as each other, then you should only need to map the buttons for the first controller. The MiSTer sees the first USB controller you touch as the player 1, and the second USB controller as player 2, and both have the same button mapping. If...

Neat! It would be cool if it was integrated with a colorimeter.

Thanks! I had comparable pictures to most of those. See the comparison here:

Thanks! I have a ton more pictures I took previously for akeley's project so I can post more too. I think from even these two pictures that it is clear that the color artifacting is not as present in the IIgs version on the RGB monitor. For example the buildings on the right look quite different. Also, the blue is very different which is interesting.

Thanks! Yes, that definitely works. I forgot to mention I have a Mac LCIII with an Apple IIe card in it. The Mac LCIII effectively uses a VGA monitor, and I can tell you that the above picture looks way better than the Mac does. Your picture has that grain to it that disappears on the Mac. Also, I can see the color fringing in the M in March. I thi...

thorr

You can actually turn that color fringing on the text off and on in the Apple IIe core in the core menu. It's a special MiSTer core feature that a normal Apple IIe can't do. It is normal to have the weird colors on the text when in graphics modes, even on my Apple IIc with composite monitor. It will be interesting to see how it looks on screen comp...

throttle 1, syncrefresh 0 still works for me for Starwars/Spy Hunter. Also, mister_interlaced_fb 0 helps eliminating the interlace artifacts when disabling syncrefresh. I figured out the problem, and now California Speed, Spy Hunter and Star Wars work. In the core menu, I needed to change Volatile Framebuffer to Off. Thanks again for your help!

throttle 1, syncrefresh 0 still works for me for Starwars/Spy Hunter. Also, mister_interlaced_fb 0 helps eliminating the interlace artifacts when disabling syncrefresh. Thank you for checking! That is strange. I have two different MiSTer's with two different TV's and the both show a black screen. I must be missing another setting somewhere. I rese...

thorr

What I'm saying is that the IIgs is not "the Apple II" in that sense. The classic bitstream only exists internally between two of the custom chips, one of which digitally converts it to RGB. So while the composite output necessarily has artifacts, I don't know that there's anything special about them compared to any other RGB system with...
