B&W GPU feature

Phoenix · August 19th, 2002

I was reviewing all PSX GPU's and no one has a black and white output mode, I mean you can't see the game in B&W, wouldn't it be possible GPU authors to add such a feature/option?. In addition a contrast/brightness controls. I'd like to see some games in B&W specially the MDECs and how much impact this may have on the gameplay. Some B&W photos look better than in color, this makes them look more impressive. How about this in a game?

What do you think, Pete?, Lewpy?, E}I{?, Nikk?, everyone?

Maybe it's possible but I think it will consume a lot of CPU power. If I want a B&W, I better change my monitor configuration.

if u want to have B&W MDECs try psinex it has a B&W option ^^

**Pete Bernert** · August 19th, 2002

FPSE has a BW mdec option as well

**Dark Watcher** · August 19th, 2002

PCSX also has the option to render MDECS in Black & White

**fivefeet8** · August 19th, 2002

Why not just set your monitor colors to "black" and "White".. Then everything will be B&W..

As for the contrast thing... Petes d3d gpu has an option for brightness control..

Phoenix · August 20th, 2002

OK, I'd like that the ePSXe team consider adding such option like those other emus like PCSX, FPSE and Psinex

**E}I{** · August 20th, 2002

MDEC in emu core can easily output B&W(easier than color

). It is harder for plugin though. I'll do it, but it will cost speed. But you'll owe me some compatibility reports

Phoenix · August 20th, 2002

alright E}I{ I'll do my best, how difficult would be to have a B&W option via GPU or emu core so the game can be seen completely in B&W? just asking.

**Kirby** · August 20th, 2002

If I want B&W, I mind of well watch some old 60's disco show.

But if you do want it. Just invert the dark colors to black, and the light colors to white

**E}I{** · August 21st, 2002

It ca not be done in emu core.Only MDEC video.
For GPU this means that i must do color conversion when picture is sent to screen. I think speed drop will be 5-15% of normal plugin performance. It is not very hard for me to write another one MMX color conversion routine(as i have many on them). Will take some time though. Some optimization work to save several CPU cycles per pixel...

It doesn’t look like anyone else has asked this question directly, so...

Why?

From my narrow perspective, it seems like games designed in color will tend to look better in color.

But I suppose this could be nice for people with 8 bit video.

**E}I{** · August 21st, 2002

Hmm. Nice idea... do B&W just for people with 256-color videocards

lol, who will use ISA videocard with P-II machine?

Phoenix Flame · August 22nd, 2002

Who would use an ISA card in *any* machine? Can you even get ISA cards these days?

**E}I{** · August 22nd, 2002

I still have one or two somewhere. Some of them were fast enough for good FPS in 640x480x256. I also still use ISA AWE32/8Mb and proud of it

**NickK** · September 13th, 2002

NextSoft supports an 8-bit grey scale video mode if that helps.

**Prafull** · September 13th, 2002

I somehow missed out the thread.

As nickk said Nextsoft does have that feature.
