It didn't seem like any of your links was to a playable version, so I had a Goog' and a paste and came up with [1]. Pretty impressive game for that amount of code, I'd say.
I've never written a line of code on an actual MSX machine (even though I was around in the 80s), it's kind of amazing the amount of emulation Magic Power we casually throw around, these days. Massive thanks to all the emulation authors and (of course) retro computer archivists.
Edit: typo, more compliments.
