WOLFENSTEIN 3D game on ZX Spectrum 128!!

Yes, I know many people has uploaded also this game&video on YouTube however last times some people can&believe the game works on regular ZX Spectrum 128K. So it works. Therefore this video is different than others: on the beginning I loaded Computer Tester to display what machine is that (ZX Spectrum 128+). Then I reset it and loaded "Wolfenstein 3D" game via diskdrive. Yes, it doesn&look as impressive as DOOM because it&made in pure 1 bit graphic (monochrome) but its engine from the coder&side is more impressive than DOOM&one. The game works fine on normal ZX Spectrum 128 and its 3,5Mhz CPU. Also please note that MP4 totally destroyed the interlace (gigascreen) effects on the intro and they¬ visible at all here, sadly. However please don&expect Pentium effects. :) That&still old good ZX Spectrum 8-bit computer.
