Hello,

You may have heard about some old educationnal games from Edmark such as :
- Thinkin' Things
- Sammy's Science House
- Trudy's Time And Place House
- and so on…

All three games listed here works approximately the same way :
- An executable .exe
- Some files .fon, .hlp, .wav
- And several resources files .res

I wanted to write an extractor for the .res files, here is how the files are constitued:

Header
byte 0-1 Magic number 0x921A
byte 2-5 Adress of the footer (i.e. 0x00485DC3)
byte 6-7 ????

The footer contains the information about the files inside the resource file.
For one file, there's 16 bytes of information. Here's how it goes.

File information
byte 0-2 Extension (i.e. ANI, SPR, SND, etc…)
byte 3-5 ????
byte 6-9 Position in the file (i.e. 0x00000060)
byte 10-13 Size of the file (i.e. 0x00000012 = 18 Bytes)
byte 14-15 ????

I wrote a small extractor in C that have been tested and works with the 1.0 French Windows version of Thinkin' Things 2 (Les Ani'Malins 2), Sammy's Science House (Sammy, la Maison des Sciences) and Trudy's Time and Space House (Lisa, la maison du temps et de l'espace).
I can provide it if wanted.

Hey there. Nice to hear about the progress. I did play a couple of Edmark games from back in the day here and there, but I mostly was a Humongous/Broderbund/The Learning Company-typer.

The alt attribute should be used to give a short description
of an image; longer descriptions should be given with the
longdesc attribute which takes a URL linked to the description.
These measures are needed for people using non-graphical browsers.

For further advice on how to make your pages accessible
see http://www.w3.org/WAI/GL.
You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.

You are recommended to use CSS to control line wrapping.
Use "white-space: nowrap" to inhibit wrapping in place
of inserting <NOBR>...</NOBR> into the markup.
