GaryMcT's Mame CRT simulation project

<< < (2/9) > >>

Ond:
Very useful project!  I just use the existing available filters for Mame to try to get that 'look' on my LCD but that system could always be improved on with your idea.

Seriously Gary if you get this going, I'll gladly Paypal you cash for beers. I've been looking for anything that taps GPU to adjust display output positively for a while, and I don't even know how to start coding a shader.

Not sure if it's of any help to you with your efforts but the best solution I've found so far is a custom D3D library called ENBSeries (http://boris-vorontsov.narod.ru/download_en.htm) - apparently people use them with popular PC games to add more dramatic looking lighting effects. I grabbed the version made for Oblivion to test with. The library simply needs to be in the same folder as the MAME executable, and it loads immediately on launch without any additional instruction (it's labelled d3d9.dll, I guess that acts as an override to the regular Win library). Also it will reference additional shader instructions in files labelled effect.txt, which looks like raw shader code. I paired the Oblivion version with the effect.txt file included for Guilty Gear, and after a lot of tweaking to both config files it uses I'm not satisfied enough to recommend it, but I really think there's potential there. I definitely like what it does for color adjustment, although the huge amounts of saturation is pretty ridiculous, and the bloom effect is interesting in very tiny amounts. It also adds a nice-looking color grading effect to the edges of the screen.

The downsides though are pretty bad - color bleed seems to work in reverse at times, with dark colors badly tinting bright surrounding colors (Rolling Thunder and 1943 show this right away) and as I said I can't wrangle the saturation down without cranking down gamma to unacceptable levels. That said, some games definitely look improved because of it.

I'll get some screenshots and my settings for you if you think it'd be useful at all. Thanks for taking this on.

Ummon:
Fascinating.

Here I tried some filters in Photoshop that preserve the brightness and contrast, yet make a decent scanline image on LCD's.

GaryMcT:
I'm interested in actually getting the offset dot pattern that you get on a CRT.

I probably won't have much to update for a while since I'm busy busy at work.
