The MSX version of Knight Lore was developed by Tose Co. Ltd. for Jaleco and published in Europe and Japan in 1985.
It is pretty much identical to the original ZX Spectrum version, complete with slowdown. That said: if you run it on a more powerful MSX computer it outstrips the Speccy original in terms of performance.
Knight Lore is a legendary game – whatever platform you play it on – and the MSX version is no exception.
