Really nice all. Also the cga version. I wonder whether that 16colors composite cga mode would also work or would it be too slow? As mentioned earlier in this thread instead of remapping all 256 colors to the cga palette, a redesign of the textures could greatly improve the cga appearance at the costs of simple flat one color textures comparable with wolf3d. Simplier but maybe more comfortable for the eyes 😀

I have a question, is possible to not loading textures? just diferent flat colors and sprites? in a plasma CGA display like mine will look much much better, because the dithering is made in real time
thanks

Yes, i will love to photoshop all textures to be more nice to cga palette, in my case b/w one. Just flat colors

For example, this textures edited will look much better in CGA

Yessss that’s indeed what I was talking about. Thanks for the example.

The resolution itself should be 320x200 as for vga but only 4 colors. Only for 16 colors you get 160x100 iirc.

Wiki:
„A number of official and unofficial features exist that can be exploited to achieve special effects.
In 320 × 200 graphics mode, the background color (which also affects the border color), which defaults to black on mode initialization, can be changed to any of the other 15 colors of the CGA palette. This allows for some variation, as well as flashing effects, as the background color can be changed without having to redraw the screen (i.e. without changing the contents of the video RAM).“

The composite mode is I think rarely something a lot of people could use as it requires special displays. Or just Dosbox but that’s not the target here 😀

For what i check, will be 240x160

For example, title screen, i think will look much better the one from 32x, resized to 240x160 and lowered to 4 colors
