Their culture sure is a bit alien. The authors are boasting about the dosbox they've broken, yet (it looks to me that) not a single bug/crash has been reported.
Edit: happily I'm wrong. Quoting ajenner below, "there are emulators (for other targets) which do emulate NTSC decoding properly, but until I did the research for this demo nobody understood how the CGA card generates composite signals well enough to be emulate it properly. I have some code which I hope to be adding to DOSBox (and any other emulators that want it) soon."
