Interesting! The oldest interpreter I have is 0.000.294; yours might have
some new weirdnesses.

I'll add the stability fixes anyway.

0x68 is usually GetSaveDir(), which is actually called very early in most
SCI programs (step #13 looks realistic).
However, only 98 (or so) kernel function names were listed, so we have to
assume that your KQ4 is missing more than one kernel function name (later
games usually don't have the name of the last kernel function).
I'll set the number of kernel functions to 0x6e for games older than
0.000.297, and call the default functions. That should fix this problem.

Actually, most kernel functions are described in the online documentation
(or you can use "list cmds" and use "man foo" to get a description of
"foo")).
The most commonly used functions are "s" and "debuglog", you might want to
check those first.
