It think it may require a good C knowledge.
Memory management is also mportant on a old machine.

I hope programming isn't different on a CISC machine that programming on RISC ones. At high level I mean.

There is another format I want to decode :

Where are the pics of the goombas, and the koopas ?
I don't know. But I suppose that they just are below each level graphics. This seems to be the only part of the *av.rtf files that remains unknown for us.

I made a webpage if you want more technical info/downloads

It's tedious to reproduce these cartoons because sometimes it's hard to determine where, when and what frame is stored in the file. Every time you solve a problem another one comes out. Instead of making the pattern matcher (that finds the images) more complex I'll try to find these data by block, t...

We are now working on decoding cd-i cartoon animations (RLE7-type images). Ive written a tool that decodes RLE7, I'm now trying to build correctly these animations.

After looking for animation data, LuigiBlood found a part of an unused one of the game http://www.youtube.com/watch?v=mI50HhDupZI

The program is being updated. If someone is interested in you can MP me.

Note : you still have to extract the image data of the files, e.g. with a hex editor.

Edit : the program now does that alone.

Thanks LuigiBlood for testing/remarks/help !

There are also strange things, images are'nt centered and some "IDAT" are not readable

The jar file may be extracted, so you can look at the sources and modify them.

(use it at you're own risks )

I will post the program here but it's not user friendly.
It isn't optimized yet, it's a prototype.

I cannot decode the videos. I dunno where they are recorded and in which format they are

yes, I will put it here

oops, I'm wrong : it is the .av files, not .am files. I've edited my previous post
thanks for noticing that

it seems that there is another one in the 7th hotel

I've opened the files ending with "av.rtf" (edit : its not .am) of the Hotel Mario CD-i with a hexa editor. Then I've looked for image data : the background images are in a CLUT-like format I think. http://en.wikipedia.org/wiki/CLUT For each image there is list of all the colors first (the image pal...

done
