Great game!
I was playing the ZX Spectrum version a bit back then and wanted to make a video of the recently released MSX version. Unfortunately, the MSX version runs ~17 percent too fast on MiSTer, because it's strangely a PAL game, but basically almost all MSX games are NTSC games (MiSTer doesn't even have an option in the menu to switch the MSX core to PAL).
With Sofa Run I was able to play it at 50Hz and the correct speed, but unfortunately the aspect ratio is ugly horizontally stretched (see: http://www.kameli.net/marq/?p=4703). Therefore a native NTSC version with corrected speed for the MSX would be desirable.
Anyway, here is an uncut playthrough video from the Amstrad version, played on my MiSTer.
