RETROZONE

Der kostenlose Atari-Emulator Stella wurde nun von der Georgia Tech Computer Science Capstone Group so verändert, dass er auch auf LCDs die Fehler der Röhrenmonitore darstellen kann. Die damaligen Spieleentwickler kannten diese Effekte und nutzten sie zum Teil auch bewusst aus, um beeindruckende Farbverläufe zu erzielen, die heute auf LCDs nur noch scharf abgegrenzte Linien sind.

This is the sort of crap that passes for an article on Slashdot these days?

Unlike the synopsis on Slashdot, this “group at Georgia Institute of Technology” isn’t emulating shit. This effect has pretty much no fundamental basis in reality, it was just a bunch of people throwing full-screen effects at the wall and seeing which ones they liked the look of. It is no more an “emulation” of CRT effects than the PNG-based filters that you can use with MAME. Besides that, the effect just plain looks too crappy.

Folks, THIS is the only legitimate “emulation” of a TV signal and its output. NRS and blargg based their work on the hard, documented math equations that involve generating and displaying an NTSC video signal on a television.

I’m sick of people heralding this group at GIT as some sort of geniuses. They don’t know what the fuck they’re doing, and I hope that they sure as hell didn’t get any kind of grant for what they did.

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."
