two (or more) different Pepsi MADMIX games?

Yes, I am talking about first MADMIX game. As I was really interested about it when I read it´s prewiev from your sinclair in the year 198X. And I instantly bought it for my own x-mas present to me as soon as it hit my nearest software shop.

But there was two differencies which kept me wondering.

In my cassette´s backside there was spectrum and amstrad screenshots which had really jolly looking hero which was really different looking to that one I had in my MSX game. THat spectrum/amstrad hero has snail-like eyes over it´s head. I thought back then that maybe that is the case with SPANISH versions, and MAYBE(?) there is same looking MSX version around in spain?

But I do remember that there was that same lovely creature in my MADMIX game drawn in the wall in level XX.

Anohter thing is... I am not sure was there YELLOW (or white) Pepsiman in Your SInclair´s screenshots... but from somewhere I have seen there IS pepsiman which has just not black and background as it´s colour but black and yellow (or white)!

And now I saw that screenshot picture in here, in Generation MSX!

Another thing is that in Generation MSX screenshot (and google gives same for speccy screenshots) there is pacman look-a-like pepsiman. Pepsiman in my game in Finland had FEET! And angry pepsiman also had feet! In Generation MSX screenshot pepsiman is pacman´s relative without feet! :)

So, are those differencies a feature only in SPANISH version which was not available outside of Spain? Or maybe sold in some european countries only...?
