I have the C64, CPC, and Spectrum versions of all 4 Magic Knight games and I've always thought the MSX versions were superior (although I've not played the 128k Spectrum versions), and I think Tracy has done Spellbound justice from this video.
I'm really excited by this.
I guess it's nice that there is finally a port for the MSX.
I must say that, I mostly remembered that this game was very hard to finish. It has a very tight time limit that make it impossible to finish it casually without some POKEs. The game also has some mechanics that won't work if you turned off the timer. I hope not too many of these features were ported to the MSX version.
