"Demoscene Collection 2" Various DOS/Windows conversions by Jonathan Campbell in his spare time. NTSC region-free DVD ISO image. Production notes: Demos were captured using the DOSBox emulator. In some cases, I had to modify the source code to DOSBox to make the demo work. One hack added an option to DOSBox's VGA emulation that forced the fake "refresh rate" to 59.94Hz no matter what the DOS program did, which was hit-or-miss depending on whether the programmer assumed the standard refresh rate. When it works it avoids the need for framerate conversion. In other cases, I had to resort to using the Bochs emulator and some backend video capture code I hacked into it. Actual emulation was done on 1) Windows XP and 2) a Linux KDE desktop. In some cases, the DOS demo switched VGA modes or had emulation/timing problems that required additional editing in Final Cut Pro. Interim titlecards were made in Final Cut Pro. Some demos included were written for Windows. These demos were captured on a WinXP SP2 machine with Kkapture v0.6 and a ATI Radeon R330 PCI-e graphics card. In cases where I lacked the hardware or platform to run the demo, I used the available DivX, WMV, or MP4 files already available on scene.org. Video was encoded to DVD format using MPlayer 1.0rc2 + some source code modifications of mine to add high quality framerate conversion. The DVD is authored with two titles. First title has demos captured in 16:9 anamorphic format. Second title has demos in 4:3 format. The DVD format does not permit one title to have different aspect ratios.

Ibiza [4:3 Windows] * Kkapturing this demo is a real pain. It won't work with the OpenDML AVI capture. Segmented capture works up until the fractal part which crashes. The trick apparently is to use a lossy codec like Indeo 5.0 so that KKapture never has to split AVI files. Futuremark - Lapsus [4:3 Windows] * Don't run this on Windows XP SP2 + Intel 855GM integrated graphics + DirectX 9. It will crash your machine and leave you a scrambled tile display. * KKapture runs the demo so slowly the intermediate loading part passes too quickly. Crapware - Byetro [4:3 DOS] * Don't panic when it "returns" you to the DOS prompt, it's fake. This crap demo is so stupid it's funny. Cave (stonage fiction) [4:3 DOS] Vihre't Lehm't [4:3 DOS] * AAAAAHHHHH! My eyes! It burns! Not for the epileptic. TDC - Beer [4:3 DOS] Hypodermik [4:3 DOS] The Project - ABCDemo [4:3 Windows] * A very funny and insulting demo about the demoscene. Uses Windows GDI only, which KKapture doesn't cover. Demo was captured instead by writing my own code to intercept calls to timing and GDI functions. Satire - Explosion [4:3 DOS] COMA - Exposure [4:3 DOS] Fields of the Nephilims [4:3 DOS] * I learned the hard way the VGA refresh rate trick doesn't work with this demo, it only seems to cause horrible tearlines in DOSBox which are very visible in this version. The re-do on later DVDs is much better looking. COMA - Control [4:3 DOS] * It looks like the rapid zooming parts are very CPU sensitive, and run too fast. DOSBox's chained VGA emulation visibly choked a bit in some places. I'll redo this one later when I have time. Angeldust Phase II [4:3 DOS] Guggle [4:3 DOS] Complex - Dope [4:3 DOS] * Given enough CPU cycles everything runs quite smoothly. The reviewer on Pouet.net is right though, if you run DOSBox slow enough (like on a 386SX) the demo will corrupt itself and cause all sorts of interesting glitches--and crash. Might be from the programmers using timer ticks with stack allocation, who knows? Upload to: ftp://ftp.de.scene.org/pub/demos/compilations/demoscene_collection/disc2
