Now I have the explanation for the fact that in Emerald Mine you can "touch" an enemy like a spaceship moving in the opposite direction - but only when the screen scrolls (and not always, ...

): At the touchpoint, the engine is scrolling and then jumps back to the frame touchpoint+1...

Bug? Feature? It is like it is

So this really also works (sometimes) in the original Amiga Emerald Mine?

I thought this would only happen in the R'n'D engine...

Yep! That's why they call it "trick" in the Supaplex community... ;-)

Ah, I thought that it will be what it is. However, I wasn't sure if it really is it, so I asked what is it, and now I know that it is what it is. (Or isn't it?)

I'm trying to make a BD clone (read: could get released in next 10 years), and I'd like synchronised movement because of its "bugfree-ness", so I'd like to ask: what actually are the disadvantages of synchronised movement? (Except that it may not react immediately.)

Looks like I'm getting off topic. Consider splitting the thread.

hmm...original...disks with one of the EMC-engines, yes. I think all of the EMC-engines. There are not many levels based on this "trick", but I played more than 10 levels with it, and the disks where randomly drawn from the EMC-collection. (I cannot point at an exact levelfile, my level-database has not yet developed from the think-about-it-stadium

)

The "leaving-the-playfield-trick" is also code-based, I think. [If there is no border-wall around the playfield on some places, leaving left let you enter the playfield from the right one row higher with the player invisible, but very vincible; leaving right, top or bottom let you die immediatly.]
