Hi @XeNoMoRPH ,

Could you include links to the files - I'd like to look at the screens on the 6128 & 6128 Plus I have here :)

The "Roland Ahoy" logo is superb.

Old CPC, MODE 0, flip-screen, de-interlaced... by Marlus Hoffman.

roland in the caves looks nice though roland was a flea-creature not a frog and that pterry looks way friendlier than the one that kept giving me anxiety even as a child. :P

That Pirates one is nice, how's it getting colours that the old CPC couldn't do like the darkest colours of those sails?

Yeah, ok, the pirate ship picture is fake. It only can look like that on one of those newer emulators that make use of filters that have little to do with the real thing. Flipping doesn't produce such a result, neither on a real CPC, or a 'normal' emulator mode.

Right. It's time for a disk image for those graphics that deviate from the usual CPC colours and MODEs to prove that this is real, otherwise I'll a 24 bit coloured graphic in Photoshop and claim it's from a CPC.

Anyone have DSK with this Pirates picture?

Retro Virtual Machine emulator.

Weird.  So it loads in as this with the checkerboard dithering clearly visible everywhere including the sails


And then when it's loaded it suddenly blurs, smearing much of the dithering.

I assume it alternates between two similar images to try and smooth the difference out. In my experience that tends to work better on emulators than it does on a real screen, but YMMV.

1) I am assuming it either uses two pictures 'flashing' between them or shifts the screen, or both to achieve the blend effect. But this is a graphics effect relevant only to this specific emulator and there's very little to no comparison with how this would look on the actual CTM, or an actual monitor in general, or with 'proper' emulation whatsoever. So, this would be better suited in thread titled 'Awesome Pictures for a fantasy platform freely based around the Amstrad CPC'. :P

2) Every pixel pusher in the world would prefer the checkered board version over the blur fake. You need to have 'pixels' in 'pixel art', right?

Carnivius

I think it's an interesting effect and works well there but I wonder how practical it is for other things and screens and such.  The whole point of the checkerboard dithering was indeed to take advantage of the natural blur of old monitor screens and give the impression of more colours than the system was capable of, but I don't recall it being quite that well blended.  I'd have to load that up on a real CTM644 to see how well that works on the real authentic old screen but I can't at moment.

Cheers.

Ok cool when I loaded it up in my usual emulator (cap32 core in Retroarch) I can see it is indeed using the technique of flicking between two images (as stated in the original post 'flip-screen') and I made a gif of them to easily show them.  Still a neat thing but yeah only works in specific cases. Either frame looks great on it's own anyway in my opinion. :)

Yes, this 'flipping effect' shown in the above video is what you'd get using such tricks. I believe one of the first times (if not actually the first..?) I saw this put to use was when Face Hugger's Megademo was released back in... 92? You may take a look here (at around 11:40):


Anyways, the colour blending as shown in the 'Pirates' pic as initially posted by Xenomorph, is unlikely to happen on anything but specific emulators featuring unrealistic filters.

andycadley

There was some discussion of similar effects on one of the Speccy forums (I forget which) as some LCD displays blend frames in a way that creates a similar effect.

When various people tried it out the conclusion was that the results varied wildly between displays (and probably settings on them) so it wasn't really an effect you could rely upon for "modern" games or demos.

MaV

Since the flipping effect relies on switching every frame, unless the picture shows a 25Hz flicker it doesn't represent the true depiction of the graphics on a real machine.

Personally I can live with the pixelated graphics quite well. What I don't like are 25Hz flicker or interlacing of screens on the CPC. There are some nice technical achievements done with these but it's not comfortable to look at for a prolonged period of time.

Also loading screens cannot take up too much memory, because you're meant to be loading the game into the memory! So this might work on a cartridge perhaps, but on tape/disk you need that memory the other flip screen is taking.
