gdement Posted July 6, 2004 Share Posted July 6, 2004 I recently made a palette in "The Gimp" image editor which reflects the colors available on the Atari 7800. It might also be useful to other people that want to experiment with some 7800 graphics, so I'm posting it here. My procedure was: I loaded the color test cart in MESS 0.82, copied the screen to an image file, then used the color pick tool and added each color to a palette. Hopefully the colors in MESS are decently accurate. In the process of doing this, I noticed that all of the ?E colors are the same as the ?F colors. (i.e. the brightest column of colors was just a duplicate of the column next to it) Does the 7800 really only have 240 unique colors, or is this a MESS artifact? atari_7800.gpl.zip 1 Quote Link to comment Share on other sites More sharing options...
Bruce Tomlin Posted July 6, 2004 Share Posted July 6, 2004 Considering that the 7800 uses a resistor ladder network, I don't see why luma 14 and 15 should be the same. This sounds like either a problem with the emulator or how it interacted with your video drivers or with the way your screen capture was made.

gdement Posted July 6, 2004 Author Share Posted July 6, 2004 I checked and made sure my screen mode is in 24-bit color, but other than that I guess it's probably beyond my control. oh well. Quote Link to comment Share on other sites More sharing options...
+Mitch Posted July 7, 2004 Share Posted July 7, 2004 I think the PAL 7800 colors are actually slightly more accurate in MESS than the NTSC counterpart. You really need a real 7800 to see the actual colors. Mitch Quote Link to comment Share on other sites More sharing options...
