I made a sample roms with pictures compressed by aplib, packfire and lzss: Sega_Pics_packed.7z (if u can't download try IE or Opera, or get from dir download Shows: packed size (uncompressed size of all = 38,400 bytes.) compressed % unpack time in frames. Press any button to see next picture. packfi...

15, 980Kb? I'm assuming you mean ram. I can't imagine the code/decompressor taking up that much rom space. It's no where near that on the 65x version for code length. Yes, Ram. Example for genesis games: level tileset = ~30kb+ 16kb ("probs buffer") wanted by packfire (=18 kb for other game data)+ w...

Well , I've test it.
Packfire requires additional 15, 980 Kb of memory... and it's very very slow...
'Tiny' mode doesn't require it, but can't pack large files.

I use it when speed does not matter

Thanks, I checked it, compressed my tiles better than others, and even better than 7-zip. Don't know about speed.
'Tiny mode' better than zip.

Some games have unique or interesting graphics compression formats. What is your favorite graphics compression format for the Sega Genesis? The Nemesis compression format is entropy-based, but it takes a long time to decompress. Files with many long runs of the same nybble are best for this format....

I use Ximagic plugin to convert the colors to 9bits (RGB333) http://www.ximagic.com/cd_index.html There are plenty of configuration to change the dithering pattern. Then I use a professional tool to generate the 4 palettes and tile repartition. (can't post this one sorry) For what reason you can't ...

ppm install was successful? Which dll is missing? CORE_RL_magick_.lib I've used Frederick's method, now all works fine, that it: - Uninstall Perl & ImageMagick (may not be necessary but it's what I did). - Install Strawberry Perl 5.16.3.1 - Run the command line interface (cmd). - Type cpan (it shou...

scolorq lab 15 genesis colors. I think, it's impossible by hands :S Now I see, it's look much good, than RetroGfx output. ([s]retro loses green color of grass[/s]). 2) it can't make 4 rows for this pics (makes only 3), and increase of color count will not add green. I will try your and Frederic uti...

I have a slightly better image with additional layer to this pic. (color count same, just for remove artifacts)

Why you asking? You know all about this pic, it even was made in your program.
Of course it 1-layer, each tile use only it's row.

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. What can I say, there's no one ideal algorithm....

"r57shell": You version looks better!

frederic colors = 29 and artifact on scorpion
sega16 = no visible artifact, but 24 colors.
you version = no visible artifact and 28 colors.

I don't know it. 2) Install with options: install for ActiveState Perl and remember version . I tried this order (firstly unistalled all), and it show me version 5.16.3 - that was same version that I have. So, nothing changed - error msg with DLL. And I aslo tried scripts from folder. (I used trick...

This is your problem.

Can you write which versions of Perl and Magick works with together?
