PCem

Hi,

seems, that DOSBox and PCem (linux) render the colors differently .. colors look too bright in PCem for the 18bit RGB values ?! It doesn't matter, if software or openGL rendering ..

What are you running in these screenshots?

PCem looks too bright... does it happen on every game?

Is DOSbox in machine=vgaonly?

My own project .. using nothing special, just changing colors in mode 13h the usal way with palette registers .. added the RGB value in the left screen to show the difference, its the color of the field where this color is used.

@leilei: its set to svga_et4000 .. changed it now to vgaonly and - same brightness ! wtf ? are there really differences between the chipsets and card ? (at least in PCem it doesn't matter) ..

A RGB value like 1,6,5 should be really dark .. hm ..

btw. the internal font roms are different - the 8x8 vga font's first line is clear in dosbox (the letters points start the second line), in PCem they start with the first line .. I guess it correct in PCem when using the real vga roms !?

hm .. interesting, seems that the green channel has technically a higher brightness level

obviously with vgaonly dosbox tries to be as compatible as possible, so PCem does it correctly ..
