I was playing around today with making the same image for multiple platforms, just for fun.
I made
  • a 16-colour Amiga version
  • Amstrad CPC version
  • Amstrad Plus version
  • C64 version
Also uploaded the original.

Everyone feel free to make more versions. I'm curious what it will look like on other platforms.
Do you need music for your Amstrad CPC game project?
Take a look at IndieGameMusic.com - that's where I put my tracks.

If I am not wrong 16 for all 5 :)

Two more: Amstrad CPC MODE 1 and MS-DOS CGA.

I wondered about that too! But I just use the tools. :)

If so, how does the Amiga version look so much better than the Plus one? Palette choice?

Most graphics conversion programs, when they reduce number of colors, choose those that have more pixels on screen, so sometimes important color that does not have many pixels disappears in new palette, but you can set this color manually and lock it, then program will use it. Because your color selection may be better than automatic, especially in MODE 1.

Yea, I'm not graphics artist. Real artists should be able to do much better.
Just wanted to experiment, see how much effort it takes to create multiple versions of some graphics. Doesn't seem to take a lot of effort.
So to me it seems like a good idea for pixel artists doing stock graphics to create multiple versions of their creations, to increase chances of gamedevs finding it useful on their particular platform.

The Amiga (320x200x16) has the double resolution compared to the CPC Plus (160x200x16).

Ah I read the dimensions of the images...

SNES (256x183), 256 colors RGB555. To account for the 8:7 pixel aspect ratio I had to upscale the picture for PC viewing, and some interpolation was necessary. No original HW picture (yet), sorry :)

Please excuse the double posting; I should add that this is for SNES graphics mode 3.

Wonderful image!  :) well done!

I was expecting a totally different thing, however    ;D
I was wondering, how it is physically possible, to
make a disk image compatible with all computers. :doh:

Probably worth a new topic on its own, but I seem to recall magazines with a cover disk that would work on both Amiga and ST... Not sure how they did that, am I right in remembering that ST's use a an MSDOS disk format?

Maybe a special boot sector for the Amiga and the rest of the disk in DOS format, or were these genuinely mixed format disks?

McArti0 did this:

You can make hybrid discs, which contain both a CP/M filesystem and a FAT12 filesystem.
The first can be read on a native level by an Amstrad CPC (and probably other CP/M machines) and the second can be read on a native level by MSX, Enterprise, NC200, later PCWs, PC, Atari ST (?) [and of course any SymbOS machine].
I think there was another specific thread about this topic here as well.

This is very well explained here:

mr_lou

That's also an interesting topic yes. :)
But yea, should probably be split into another thread, if more replies comes along.

I'm personally also a fan of the way Xbox games - when put in a normal DVD player - shows an Xbox logo etc. Not quite as geeky of course, but still...

Making such a disk actually qualifies as a form of steganography, which is the art of "hiding data in plain sight" within some other data - which is also an interesting topic. :)

Did another version: Amstrad CPC MODE 0 interlaced.

I wonder what the cons are with interlaced images. The advantage of course is that we suddenly get a palette of 125 colours instead of 27. And I know that one con is that a lot (most?) emulators doesn't handle it that well, which is why many YouTube videos give a terrible impression.
What other cons are there?

And then CPCEC is used which can easily bind the interl into one color.

Yea, RetroVirtualMachine also does a great job with interlaced colours.

But there are still videos made even today with flickering colours, which can only be because of either poor emulation or bad settings. Maybe that's all it is? Bad settings?

On a real CPC and monitor, you get horrible flickering colours and it's migraine inducing to look at for any length of time. I'd argue it's poor emulation to conceal that fact by deliberately blending frames to make it look smoother.

If you mix black'n'white - or two other strong contrasting colours, then it will result in horrible flickering yes. And yes, it is therefor poor emulation to just show a steady grey colour.
But if you pick two colours that are relatively close to each other - which is all you need to produce one of the additional colours from the interlaced palette - then it definitely shouldn't qualify as "horrible" flickering. You may be able to see it, but it shouldn't be annoying to look at.
