This game made me laugh. It is so weird. Mixing My Little Poney with rap is surreal humour. Is it made on purpose? When I see this , I guess you didn't make this game very seriously.

Like djcouchycouch, I thought it was your first production, but I ...

Congratulations! Now we have a second Megadrive emulator for Linux that is still maintained (the other one being DGen, but maybe there are others that I don't know of). It's still limited to x86-64, but at least it is not limited to Windows.

It seems to be very fast, I tried to run 6 instances of ...

I am also interested in what the include instruction does. If you put 'include abc.asm' on top of some .asm, will the content of abc.asm be the one that is first executed when you compile and run .bin?
"include" is a directive that is interpreted by the assembler (ie by asm68k), not by the ...

Nice interview. Thanks for the transcript, it's very useful for non-native english speakers like me. I'm glad you asked some details about the "3D chequerboard effect", which is the effect I like the most in the Overdrive demo.

Wow. When I see this, I consider quitting Megadrive development :-). I love the effect when there are several layers of squares, at about 4 minutes.

Well done. Did you consider using 1bpp instead of lowering the definition? When I watch this video in 1bpp I find it's better to lose on the colors rather than sharpness. I don't know if it could fit in 4MB, though.

frederic , what different clustering algo instead of K-means can be used? And may be use another tile representation for clustering?
Algorithm::Cluster provides several algorithms (k-means, k-median, k-medoids...). I tried k-median and it gave better results in some cases. You can try to play with ...

Line 296:
$image->Remap(image => $colorsimage);
Oh, sorry. You're right. I looked at it again and did not see this. The images are quite different (worse, I'd say) with this bug corrected. I'll do some tests to see what to do (to transform the bug into a feature or to correct it and change other ...

Your bug. You must turn off dither explicitly.

From ImageMagick's documentation :
dither=>{True, False}

In my script, insert this just before Quantize() or Remap() is called:


if ($options{dither}) {
print "This is a true value\n";
} else {
print "This is a false value\n";
}


You'll see ...

Because Remap function of ImageMagick used dither by defaut even if dither option not set. It is bug of version by frederic .
It's not a bug. The "dither" argument is passed to imagemagick's functions with a false value, to disable dithering (see this ). When you enable dithering, the script is ...

True, Ti_. r57shell's algorithm seems to be better on some images (drawings with big area of flat colors). See the comparison with the picture you just gave.

Ti_ wrote:If dithered disabled, why this image looks dithered?

It seems that my algorithm (a series of quantization/remapping applied to the whole picture, then to small parts, then to tiles) induces dithering, though no explicit dithering algorithm is applied.

My version works in about 10 seconds, much faster than version by frederic .
Indeed it is a lot faster. But the results are not as good with some images.

For example, below, the first row of images comes from your script (from left to right: dither=0, dither=1, dither=2). The bottom image comes ...

Goto tilemap actions->Dither tilemap as image
Then pick how you want the tilemap dithered.
So it was me. Thanks.

I've tried to download activeperl, strawberry perl, imagemagick plugin, tried to reinstall image magick with 2 options: install enviroment and install for active perl. Tried to use ...

Could you please explain why you can't get it to work so that I can fix it for you?
Sure. I just downloaded the last version just to be sure (https://github.com/ComputerNerd/Retro-Graphics-Toolkit/archive/master.zip).

I run it, then I chose File > Import image to tilemap . Then I chose Palette ...
