And lower saturation if you haven't already. But you might need to play with the gamma settings. It does seem to make, for example, the nes output closer to my old crt PVM. This would correspond to correctly converted YIQ but then converted back to RGB with your coefficients (barring typos). But you'll need to edit the hlsl.json to allow negative slider values.įor example, if I type the matrices into wolframalpha mostly correctly and copy paste the result, the result is: Either the BGFX version or D3D will work.
NESTOPIA UNDEAD FULL
To get the full RGB->YIQ->RGB you multiply the matrices together in the correct order (YIQ->RGB)*(RGB->YIQ) and use the result in the color convolution section of the hlsl shader.
(2)Get the YIQ->RGB matrix from your post (1)Get the RGB->YIQ matrix from wikipedia.
If you want to try out this effect now (it might be wrong if we need to do some kind of gamma correction first) you can do the following: It's interesting how far off these are from the formulas on the YIQ wikipedia page. But I'm still surprised at how far off the YIQ->RGB formulas are from the standard ones you see everywherw (like wikipedia). Now that I'm not on my laptop out in the sun I see that this is pretty bad on a calibrated monitor. When selected as a palette option, the color hues are spectacular, nailing the way respective console and computer systems appear when displayed on many highly utilized and popular computer monitors and televisions.įor those interested, the conversion formula (RGB -> YIQ) for this particular decoder matrix is as follows:ĮDIT: Nevermind. It is also applied to (forks of) the Gens/Genesis emulator as well as a part of the TwoMBit-Core featuring SMS emulation for OpenEmu. Things were better in the '90s.#353026 - 04/15/16 01:33 PM Attachment: SONY_CXA2025AS.zip 388 KB (7 downloads)Ĭurious if anyone has insight regarding palette output, as processed through the Sony CXA2025AS US decoder matrix, whether it can be implemented as an option with all the various shader and video filter possibilities currently available for MAME (?) You'll be forever in debt to my priceless advice. Check it out, it is way more capable than it seems. Best yet, OpenGL is a first class citizen, and you can even use modern OpenGL without any problems. It gives me a reliable, slow-moving target and is simple enough that it takes little effort to work with if I want to build new features. GTK was also driving me insane, and despite all my rage, they continue to avoid fixing broken features.įor a '90s style program, I highly recommend FLTK. The change should really pump up performance on older systems. not that there's anything wrong with that.
NESTOPIA UNDEAD WINDOWS
This makes it look and feel like a vanilla Windows 95 program. To celebrate the '90s, Nestopia's Linux port was moved to FLTK and oldschool OpenGL 1.x. If you weren't alive at that time, you missed a million miles of fun! Maybe you were a loser in highschool, but you were cool online. For the first time, you could quickly communicate with people around the world, a monumental thing at the time, though often bittersweet if you were on AOL. There was great music, and the sense that there was no limit to how awesome the future was going to be. The NES was a system from the '80s, but it did catch the ninja craze and most of us were playing it in the '90s anyway, both because it was still a great console and because our parents had beef with the cost of games. This release is dedicated to the best decade there ever was.
