Yeah, hopefully Simius will release a few versions with different palettes. I don't mind the PAL palette (prefer it even), but I can imagine Americans want an NTSC palette because that's what they're used to.

+S.D.W. Posted March 28, 2017 Share Posted March 28, 2017 I was wondering why not just use the standard 10-pin IDC JTAG connector? The USB Blaster (which you need to update the firmware anyway) already includes with this cable. It seems Micro-Match connectors are not very common here in the U.S. Quote Link to comment Share on other sites More sharing options...
robbievgb Posted March 28, 2017 Share Posted March 28, 2017 a little disappointed to hear the colors are off (pink donkey kong / breakout/ pacman), specifically to 5200 because that's what I have ...but I believe this is how Sophia current works on all systems Will additional color pallets be available some how? I'm still confused because half the people here don't seem to think there's anything wrong with the colors. I was wondering why not just use the standard 10-pin IDC JTAG connector? The USB Blaster (which you need to update the firmware anyway) already includes with this cable. It seems Micro-Match connectors are not very common here in the U.S. I picked up both of these from DigiKey: https://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/1-215083-0/A107014CT-ND/3488575 https://www.digikey.com/product-detail/en/terasic-inc/P0302/P0302-ND/2003484 Can you defined, what means the "NTSC color profile"? Where is the pattern? My apologies I guess I meant "palette" not "profile". Simus - It sounds like with your latest planned revision, we can now switch between palettes with a command. Awesome. However, this is not a viable option for Atari 5200 installs. Is it possible to make a .pof file(s) available with a specific palette already set? This way 5200 owners can use whatever palette they like. Don't get me wrong, this is an awesome product you've made, and the video quality is fantastic, I just want to get an accurate representation of what I'm used to seeing on my 5200. 1 Quote Link to comment Share on other sites More sharing options...
Simius Posted March 28, 2017 Author Share Posted March 28, 2017 You misunderstood me. There will not be many palettes to choose, because the palette implementation isn't easy (it is made not as array, but by logic - Max II series hasn't fast enough, user flash memory) and there is to little resources to implement more than one. I can change the actual palette, but I'll not make many "user defined" versions. It have to be a common accepted pattern. There is several known palettes, which indicates that Atari color perception isn't uniform. For the reason of the potentiometer on board, TV/monitor properties, color system differences e.t.c. The datasheet definition is very poor. How to determine, which palette will satisfy everyone? Quote Link to comment Share on other sites More sharing options...
+Philsan Posted March 28, 2017 Share Posted March 28, 2017 I think it's not possible to define ONE palette that satisfies everyone, Europeans and Americans. It is possible to define TWO palettes, PAL and NTSC. Regarding PAL palette, I prefer Altirra default PAL palette (attached), so emulator matches real Atari.

Simius Posted March 28, 2017 Author Share Posted March 28, 2017 (edited) Altirra palette: Donkey Kong - pink, Pac-man - even more pink. Not good. Edited March 28, 2017 by Simius 1 Quote Link to comment Share on other sites More sharing options...
+Philsan Posted March 28, 2017 Share Posted March 28, 2017 I agree on the fact DK and PM colors are not good. Maybe because those games were programmed with NTSC computers in mind? I have to check my real PAL hardware to find out if Altirra palette is off or the games were made for NTSC not caring about PAL. In general, I think PAL palette should be similar to real PAL hardware. Otherwise software made for PAL hardware would have incorrect colors. For example, Rastaconverter images made with PAL palette are not good on NTSC machines, and viceversa. Only one palette, suitable for NTSC and PAL would be nice, but sometimes software is conceived for NTSC or PAL palette, not caring about the other palette. 1 Quote Link to comment Share on other sites More sharing options...
Ely Posted March 28, 2017 Share Posted March 28, 2017 Those Donkey Kong colours shown in that Altirra screenshot look like my PAL colours on real hardware, and how I remember them from back on the day. 4 Quote Link to comment Share on other sites More sharing options...
+mytek Posted March 28, 2017 Share Posted March 28, 2017 I would think that the idea is to be true to what either a PAL or NTSC system would look like in reality, and not to fix what was ill conceived in the original program. So in other words if something looked pink on PAL, but was brown on NTSC while using the original hardware in a factory setup machine, then that would be the target to shoot for. Two different video standards require two different palettes, not a one size fits all. Ideally to be compatible with both the 5200 and the computer series a jumper setting would be the most practical, or two different CPLD code sets if the CPLD doesn't have the room to store and/or switch between both palettes. Am I far off base here, or does this make sense? - Michael 3 Quote Link to comment Share on other sites More sharing options...

Justin Payne Posted March 28, 2017 Share Posted March 28, 2017 Yea, I'm ready to pull the trigger just as soon as the NTSC colors are correct. Quote Link to comment Share on other sites More sharing options...
+Philsan Posted March 28, 2017 Share Posted March 28, 2017 As promised, I checked my PAL Atari 800XL with s-video output. It has exactly the same colors of Altirra PAL default palette. Donkey Kong and Pac-Man on my real hardware are identical to the screenshots you posted. So, I would like that my Sophia board reproduces exactly PAL colors (not NTSC colors) using Altirra PAL default palette. I think NTSC friends would like that their Sophia boards reproduce exactly NTSC colors too. Altirra is a fantastic emulator so I think its NTSC palette is accurate too. I attach Altirra default PAL and NTSC palettes. Altirra default palettes.zip 3 Quote Link to comment Share on other sites More sharing options...
tuf Posted March 28, 2017 Share Posted March 28, 2017 I don't understand this - did Atari actually release Pac Man with different colors for NTSC and PAL? Aren't we just seeing the different interpretation of colors between the two, and if so, why isn't this simply rendered properly by the hardware or Altirra (ie DK and PM should look the way they did on the real hardware regardless)? Pac Man dots are, and should always be yellow. Did PAL users actually live with those colors all their lives? 1 Quote Link to comment Share on other sites More sharing options...
+remowilliams Posted March 28, 2017 Share Posted March 28, 2017 I think NTSC friends would like that their Sophia boards reproduce exactly NTSC colors too. Yes. Definitely. 4 Quote Link to comment Share on other sites More sharing options...
robbievgb Posted March 29, 2017 Share Posted March 29, 2017 That's the point I've been trying to make since the beginning. It's obvious there's a significant difference between at least the two to warrant one PAL and one NTSC palette. I understand that it's impossible to meet everyone's tastes. But I think making an alternative to reprogram to use an NTSC palette palette isn't much to ask for, given that the general consensus is that the Altirra NTSC default is palette is perfectly suitable. If you really don't want to deal with it, then at least release something that would allow those of us interested to modify it to our own needs. 2 Quote Link to comment Share on other sites More sharing options...
