For anyone else who wants to test, here are the changes from my last patch: in vga_other.cpp, find the "#if 0"..."#endif" section and replace it with static const double gamma = 2.2; double R = Y + 0.9563*I + 0.6210*Q; R = (R - 0.075) / (1-0.075); if (R<0) R=0; if (R>1) R=1; double G = Y - 0.2721*I …

If you really need to use function keys at all, please at least let me set an initial hue and brightness setting in the configuration file. For most games, it becomes quickly obvious which setting is best, and I shouldn't have to adjust it with function keys every time I run the game. That's fine …

I tested some of the earlier talk about hard-coded saturation values and color correction: In the old CGA, burst is too large, so saturation (or composite) should be reduced to 56% of the original. In the new CGA, it is too small, so saturation should be increased to 143% of the original, making …

hah, Moraffware... take a game that's actually pretty good (and even quite advanced for a one-man effort), add support for every SVGA chipset on the market, then give it genuinely awful graphics and a clunky Borland-y presentation - congratulations, it's a Moraff! also: I can't think of any other …

A key for switching between functions could decrease amount of entries in the mapper to even 3 (so the way it is now). And I think it is always better to have these functions even in this form in the mapper compared to not having them at all. They are not that important so don't have to be easily …

You can add a contrast control like this: Y = contrast*Y/4.0 + brightness; I = contrast*I/4.0; Q = contrast*Q/4.0; And you can automatically adjust the contrast when adjusting the brightness to keep the white level the same like this: contrast = 1 - brightness; Thank you - that works nicely enough. …

ah, thanks for the heads-up. Now that I checked, the issue doesn't happen with Megabuild 6 - it seems to calculate aspect in an entirely different way, which I assume is more proper than a workaround. Hopefully this change will make it into SVN at some point.

they don't even need to focus that hard in order to make a good game here - all the magic ingredients are already there in Carma1... I'd be perfectly fine with it if they simply take that basic gameplay and enhance it with modern graphics, networking etc.

it's called "incentive" and I absolutely do not think it's going to suck - they've been working on this game for almost a year now, and sending a few signed goodies or throwing a release party aren't exactly mammoth tasks that would hog all development time. Really looking forward to this, seems …

Something I noticed when playing around with CGA composite output. Using "machine=cga" and "aspect=true", the CGA's regular 640x200 2bpp mode is correctly scaled to 640x480. However, in composite output mode (M_CGA16), the same underlying resolution is stretched to 640x551? this happens in both 0.74 …

Nice! Color me impressed, too. :) The authentic MDA 9x14 font is used in the above screenshots, which seems wide-ish because there's no aspect correction, but you can use any console font you like. In case that anyone does care about the aspect ratio, attached is a Windows console font that works …

Brightness is just a constant value added to the composite signal, or equivalently luma (or equivalently R, G and B before doing any gamma correction). Probably the easiest way is to add it to luma, changing: Y/=4.0; to Y = Y/4.0 + brightness; If that doesn't look like NewRisingSun's images then I …

Trying to mess around with adjustable saturation/brightness, for testing. What would be a good algorithm for brightness control? There are various models for calculating brightness, but we'd want something that produces similar results to NewRisingSun's Championship Golf images (top of page 17 in …

Maybe it would be possible to make dosbox's screen change a bit (forward and back) when function is being changed. For example screen will become brighter/darker for a while which would mean brightnest was chosen, etc. But I am not sure whether those features will go into the main dosbox build, so …
