Atari Emulation of CRT Effects On LCDs

An anonymous reader writes "A group at Georgia Institute of Technology has developed a fun little open source program to emulate the CRT effects to make old Atari games look like they originally did when played on modern LCD's and digital displays. Things like color bleed, ghosting, noise, etc. are reproduced to give a more realistic appearance."

    What about the Apple ][ screensaver?

    I think it did something very similar.

    (hey, first post!)

    Because old systems counted on it. They were designed around working on low rez NTSC displays. You find that the color bleed and fringing and such helped smooth out the image and make it more natural. When you display it on a modern high resolution LCD it looks extremely blocky. So you emulate the problems with the older technology and you get a better looking picture for it.

    One of the most widely used Blargg's NTSC libraries. Many console emulators make use of them. This new one just looks to be more advanced than most of the preceding ones.

    It is beyond me why anybody would want to make something look like it did, instead of how it should look.

    But this IS how it "should look". It was designed for that display. People want it to look like it originally did for the same reason that people like muscle cars, vinyl records (complete with the hiss and wow and flutter that they try so hard to eliminate), valve amplifiers. It's because sometimes the inaccuracies in equipment change the signal for the better, and people like that.

    Wait, you need two ports taken up so you can display on a 30" screen?

    Crap, I'm still using a single 15-pin D-SUB to connect to my 32" 1080p LCD on my old computer.

    I'm betting you're using a Monster Cable. That other guy has to use two because he is using normal cable.
