Kyokugen and Pleasure hearts are two different games, afaik. You can obtain Kyokugen at MSX Worldwide...

If I'm not mistaken, I bought that CD some time ago on a Bussum MSX fair... Pleasure Hearts afaik *IS* Kyokugen, though the release names differ for Japan and Europe... Not 100% sure about it, though.

That's right ... I was confused by the Excite translation about the CD with music of actually 2 MSX games, as mentioned here :

Actually Kyokugen is the 2nd part and Pleasure Hearts is the third part of the same saga by MKai.
Pleasure Hearts came with +PCM, a piece of hardware for the sound effects of the game. But it was sold quickly so the only games which arrived to Spain via Saver did not come with it.
Kyokugen is vertical shoot'em up while Pleasure Hearts is horizontal. And it adds support for turboR (or at least MSX2+) if I remember it well. The game was smoother then or added some stuff... it was time ago, I don't remember it that well.
PLEASURE HEARTS MUST HAVE!! T_T
*gnarl
Yes, it's a must have, but now is nearly impossible to find it 
I only have a demo here (it's a demo because when you finish 1st level, game is over) and there is no distributors for this game. Also, M-KAI as far as I know, doesn't exist now.
