@Latok, thanks for the tips. Today I won't be trying, but I now know what to try next.
@SjaaQ Thanks for the Hydragon tip as well although I hope I don't need to take a look. 
About the case: I did put the coin in the blender, yes and at that point I was already a bit like "Really?". If that sounds like a reasonable action to take, then I'm just from another universe... but I'm not expert of the genre, so I let this one go. At least I figured it out my self.
Yes, I also did try to pick up hair, but my character did not want to do it, because he thought is was full of fleas or something like that... Somehow it seems like natural that you need to talk many times, but if the character specifically says that he doesn't want to pick something up, then I tend to believe that the action is really incorrect. My fault, I did not know the "rules". I also tried to throw the seagull with a rock as this sounded like a logical thing to try on a game like this, but the message was something like "You need something like a ball"... If you send player searching for a ball and then the correct answer is to just try again and again, I want to throw the rock towards developers. I hope it turns out that I have just accidentally messed up something instead. Although the game does not need to always keep player from the hand, it does not feel fair if script writer sends player intentionally to wrong direction when he tries the correct action.
Hehe, this is a thin line to walk: if all the actions make sense in a point and click game, then probably the game will become too easy. So, most of these games have very obscure and absurd action you need to take. For example, recall that in The Day of the Tentacle, at some point you need electricity, and what you have to do is to "wash the car" (as "everyone knows" that it always rains after washing your car), and then collect electricity from a lightning haha 
@SjaaQ BTW few technical things that I noticed while playing SD... I think these are just little parameter tweaks related to "Go Go Gadged arms" If you are on kitchen in front of the window and you walk down so that you hit the ladders, you still can't reach them. There are very similar problems on the Hotel yard when it comes to broken sofa and the dumpster. (You can't reach dumpster if you stand on front of it)
BlueMSX is not recommended by N.O.P. but I think your problem is that you have wrong firmware on your HDD interface. (The HDD interfaces supported by BlueMSX can't boot from FAT16 partition) I just tried to insert Nextor ROM for Sunrise IDE (trough manual insert) and the HDD image started just fine.
You are right, it works perfect with Nextor, thanks!
I know that OpenMSX is better option but when I can't use my Zemmix Neo (I don't have OPL4) I like to use BlueMSX for a nice feature: it supports MSX native resolution at 15khz (I like to play still in old CRT TVs)
