Glulx decompilers: graphics and sounds?

(I also asked this question on RAIF.)

I used Mrifk, a Glulx decompiler. It seems to work very well to find all the text from a game.

I’d like to know if there’s a similar program which can retrieve all the graphics (.jpeg, etc.) and sounds (.ogg, etc.) files from a Glulx game (a .blb file)?

OK, don’t worry: I had an answer to my question, and it worked!
