Making Old Games Look Good On Modern LCDs? 367

75th Trombone writes "I'm a fan of several old PC games — the Myst series, StarCraft, Diablo, etc — with 2D graphics that run at a low, fixed resolution. These games all look horrible on modern LCDs. If you run them at their original resolution, they're tiny, and if you upscale them they get all sorts of blurry, pixelly smoothing artifacts. My ideal goal is to run these games at exactly double their original resolution — running 640 x 480 games at 1280 x 960, for example — so that each original pixel takes up exactly a 2 x 2 block of screen pixels, yielding graphics that are perfectly crisp and decently big. I've tried arcane settings in graphics card drivers (new and old), I've tried forcing the OS to run at a given resolution, and I've tried PowerStrip, all to no avail. Short of writing a new, modern engine for my favorite games, is there a reasonable solution to this problem?" There have been many community-supported graphical overhauls of classic games — feel free to share any you know to work well.

      I once wrote a tool called "StarPatch" that lets you run StarCraft in a window. It works by 1) patching a calls to CreateWindow and some DirectDraw initialization functions, 2) patching calls to DirectDraw's Lock and Unlock to return a fake video memory pointer, and 3) periodically copying the fake video memory to the real video memory.

      The source code is almost ten years old at this point, but I've made it available again at http://www.cs.washington.edu/homes/supersat/starpatch.c [washington.edu]. You'll need to tweak it to work with anything other than StarCraft 1.10, but you can modify it to scale up pixels, etc.

        The problem isn't just the scaling - it's that the games were designed to be viewed on CRT. Exactly 2x2 pixels does *not* acheive this - on a CRT even at low res, the CRT is more condusive to the eye interpolating detail. Crystal-clear pixels are not how older games are intended to be viewed. I've found some laptop LCDs (i.e. not huge resolution) actually allow you to play old games (e.g. on DOSBox) looking fairly similar to how they should, as the basic scaling to some extent achieves a similar effect to o

    A number of emulators already have good algorithms for scaling fixed-pixel images that preserve the sharpness while removing aliasing. Wikipedia of course has a page on Pixel art scaling algorithms [wikipedia.org]. The 2 best ones out there are 2xSal and hqx.

    The problem is that these only work within emulators that implement the algorithms. This clearly does not work for something like StarCraft. Graphics drivers (both ATI and NV) already have options to scale between virtual and physical resolutions. The ideal solution would be for them to offer different scaling algorithms that can be picked - standard bilinear or a modified one for classic games. Everything "just works" then and you get nice graphics.

    I'm not going to hold my breath on ATI or NV ever officially implementing this in their release drivers. However I'm wondering how hard it would be to add an option like this to one of the open source linux X drivers, or maybe even to Wine/DosBox. Also for windows isn't there a way to intercept graphics calls (along the lines of what FRAPs does)? Would it be possible to create a wrapper program that intercepts all the graphics calls and adds a scaling algorithm after each frame is drawn?

    Heh, this story could almost have written by me. It's the reason I held out so long on getting an LCD instead, and why I have my beloved Samsung CRT sitting still in the loft.

    I was actually quite surprised that ZSNES at 640x480 fullscreen mode, whilst there is a small noticeable interpolation effect, looked quite good. Perfectly playable once you have the graphics being displayed... I almost forget I'm not on a CRT.

    What has been a problem, though, is fast movement. This seems to be a problem inherent to LCDs. :-( Try emulating Sonic 1 (MegaDrive/Genesis) on a CRT vs an LCD. On the CRT, no problems. On the LCD, the rings in particular look fainter, and darker... well, everything seems to look a bit darker as you're running. I guess this is a small form of ghosting, and I don't think there's any way to get round it on an LCD. Any tips would be appreciated. But, I'd say that if you wanna play Sonic or the like, use a CRT.

    By the way, I'm using an NEC MultiSync EA191M.

    Try squinting?

  • Right now I'm playing Fallout 2 with a high rez patch [nma-fallout.com] on a 22" LCD. I've also got a widescreen mod [gibberlings3.net] installed for Torment, but it works with any Infinity Engine game.

  • It's all firmware controlled these days, anyway. So hack your monitor to teach it new tricks like displaying video in a subset of the actual LCD pixels available. Blog your results with code.

    This is going to sound weird, but if your version of Windows supports it, Remote Desktop may solve the problem. You can specify the size of the RD window, and a full-screen application running on the server's remote session will treat that as the maximum display resolution (meaning your graphics card should be able to stretch StarCraft to a 1280x960 RD window happily enough).

    Technically this even works for 3d-accelerated games (the DirectX commands are sent across the network and executed on the client's GPU) but for something as old as StarCraft that won't even matter.

    The catch is that client (non-server) versions of Windows don't allow you to RD from computer X into computer X again, so you'd need to have another computer somewhere with StarCraft installed, preferably located on a LAN.

    Virtualization should also work just fine, especially since there's no risk of 3D acceleration stuff being a problem with games that old. If you have Win7 (Business or higher), you don't even need to install a second copy of Windows yourself; just install Virtual XP mode, have it start in a window (rather than the rootless mode usually used) and set the window's size appropriately.

  • Two options:

    Fix it at your video card:
    Make sure your video card supports video scaling for your monitor. I know for a while, I could tell my nvidia card to handle the scaling to my display for out of scale screens so that it would either stretch, full, or not scale at all and still display using the best native resolution of the monitor by adding letterboxing (in most cases around the whole screen). The video card would thus override the scalar in the monitor as a result.

    Fix it at your video:

    Repeat after me: A pixel is not a little square [alvyray.com]. CRT monitors reconstruct an image using something closer to a gaussian distribution, rather than a crisp rectangular one [google.com] as you'd get if you simply doubled pixels. The graphics of games made when CRTs were common were made on CRTs and thus take advantage of this. The video game console emulation crowd has faced a similar issue, only there it's more than just a CRT; there's also the distortions introduced by the various composite video encoding schemes (color bleed, fringing, artifacts). You might think that removing these distortions would improve the image, but you have to realize that the artists viewed things on the same systems, and thus tailored the art to look good in those circumstances. It's sort of like a web page designer getting a page to look just right in a buggy browser, even though it looks all wrong in one with proper rendering; here you want the buggy browser, at least if you want to see the page as it was intended.

    The thing that gets me is that a high-resolution LCD could horizontally display exactly what a Trinitron CRT did, as the vertical stripe phosphor pattern matches that on most LCDs. The scaling algorithm would need to simulate the blurred-edge electron beam and mixing between pixels. There would be some sub-pixel action too, as on a CRT.

The only difference between a car salesman and a computer salesman is that the car salesman knows he's lying.
