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.
