You could use the same dominant colors but vary the brightness gradually. 2 Quote Link to comment https://forums.atariage.com/topic/315966-my-experiments-with-atari-7800/page/14/#findComment-5227345 Share on other sites More sharing options...

Defender_2600 Posted March 18, 2023 Share Posted March 18, 2023 Or maybe a better option for the 7800, use the background graphics from the Amiga version: 3 Quote Link to comment https://forums.atariage.com/topic/315966-my-experiments-with-atari-7800/page/14/#findComment-5227383 Share on other sites More sharing options...

A concern here is with the player's helicopter palette and especially against the yellow/gold background. There is a very fine line that is often blurred between green/yellow/gold, for the NTSC Atari consoles, due to some of the hue ranges that can appear different depending on display type (NTSC $1x), and some palette values, factor the aforementioned, in addition to how much the console has 'warmed-up' (NTSC $Ex & $Fx). If sticking with shades of green, highly recommend keeping it within the NTSC Hue $Cx or NTSC $Dx range for the player. Caution with NTSC $Dx though, once the console becomes hot, for the higher luminance values ($DC thru $DF), the color may start to lean chartreuse-yellow. If NTSC $1x is being leverage for the background, it will appear within a golden range (Brown-Gold-Yellow) under a CRT, and under most emulators or FPGA implementations that simulate color output under a CRT. However, the console under most modern displays, NTSC $1x will appear as shades of chartreuse at best, if not shades of green. 3 Quote Link to comment https://forums.atariage.com/topic/315966-my-experiments-with-atari-7800/page/14/#findComment-5228381 Share on other sites More sharing options...
Eagle Posted March 20, 2023 Author Share Posted March 20, 2023 (edited) I will try to not use this GFX in the future. But it's not really up to me I'm using this graphics to show capabilities of my engine. If I will start using some squares blocks then probably no one will enjoy. 27 minutes ago, Trebor said: A concern here is with the player's helicopter palette and especially against the yellow/gold background. We just had this conversation today on Polish discord and I decided to use 160B mode for Heli and Jeep, make them bigger and add dark outline. I'm getting little bit dizzy playing with Heli because everything is blending. But it's really playing much better on real hardware.

Eagle Posted April 9, 2023 Author Share Posted April 9, 2023 (edited) Reksio is beloved main character from Polish cartoon “Reksio” Beginning of this song is from cartoon intro, originally made by Lesnik in ‘90. The Duccinator made fantastic cover for YM2151 and he let me use it. It’s taking sometimes almost all cpu time, so not much left for special effects. BTW people are not aware of A7800 capabilities and they believed that this demo is made on cart driven by ARM 😂😂😂 Few more demos and they will be selling Amiga, ST, Jaguars and start buying 7800 Edited April 9, 2023 by Eagle 6 Quote Link to comment https://forums.atariage.com/topic/315966-my-experiments-with-atari-7800/page/14/#findComment-5238051 Share on other sites More sharing options...
