Modding Classic You Don’t Know Jack Games!

Hey Jan if you can can you show me how to mod ydkj game files with my own music and stuff?

Well how could I say no! And so began my quest to reverse-engineer files for You Don’t Know Jack Vol. 3 — a game that came out the year I was born. A game that will only run with a resolution of 640 x 480 x 16 colors (This is the VGA standard). A game where the internal volume slider is broken on my machine. But I did it! And in this post I will explain how.

LONG magicno srf1    -- it's an ".SRF" file
LONG filelen -- file length INCLUDING header, in bytes
LONG headerlen -- length of REMAINING header EXCLUDING the 3 already-seen longs
LONG 'off4' -- constant indicating graphics section begins
LONG numgraphics -- length of the following array of graphics
[LONG name LONG offset LONG size] -- pointers into the RAW data
LONG 'snd ' -- constant indicating audio section begins
LONG numsounds -- length of the following array of audio clips
[LONG name LONG offset LONG size] -- pointers into the RAW data
RAW data
