Looks like some more flexibility in the code could help you change things to get what you require.

Start with this for example 2 (Change all of field 5):

Code:
awk -F\* '
function rot(string,start,end,i,ret) {
   if(!end) end=length(string);
   if(!start) start=1;
   for(i=start;i<=length(string);i++) {
        c=substr(string,i,1)
        ret=ret (i>=start&&i<=end&&(c in N)?N[c]:c)
   }
   return ret
}
BEGIN{
    OFS=FS
    F="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"
    T="ZYXWVUTSRQPONMLKJIHGFEDCBAzyxwvutsrqponmlkjihgfedcba9876543210"
    for(i=1;i<=length(F);i++)N[substr(F,i,1)]=substr(T,i,1);
}

{ $5=rot($5) } 1 ' $file

Change to this for example 1 (chars 1-4 of field 5):
Code:
awk -F\* '
function rot(string,start,end,i,ret) {
   if(!end) end=length(string);
   if(!start) start=1;
   for(i=start;i<=length(string);i++) {
        c=substr(string,i,1)
        ret=ret (i>=start&&i<=end&&(c in N)?N[c]:c)
   }
   return ret
}
BEGIN{
    OFS=FS
    F="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"
    T="ZYXWVUTSRQPONMLKJIHGFEDCBAzyxwvutsrqponmlkjihgfedcba9876543210"
    for(i=1;i<=length(F);i++)N[substr(F,i,1)]=substr(T,i,1);
}

{ $5=rot($5,1,4) } 1 ' $file

voice_set_playmode(3alleg4)					  Allegro manual				       voice_set_playmode(3alleg4)

NAME
voice_set_playmode - Adjusts the loop status of the specified voice. Allegro game programming library. SYNOPSIS
#include <allegro.h> void voice_set_playmode(int voice, int playmode); DESCRIPTION
Adjusts the loop status of the specified voice. This can be done while the voice is playing, so you can start a sample in looped mode (hav- ing set the loop start and end positions to the appropriate values), and then clear the loop flag when you want to end the sound, which will cause it to continue past the loop end, play the subsequent part of the sample, and finish in the normal way. The mode parameter is a bitfield containing the following values: PLAYMODE_PLAY Plays the sample a single time. This is the default if you don't set the loop flag. PLAYMODE_LOOP Loops repeatedly through the sample, jumping back to the loop start position upon reaching the loop end. PLAYMODE_FORWARD Plays the sample from beginning to end. This is the default if you don't set the backward flag. PLAYMODE_BACKWARD Reverses the direction of the sample. If you combine this with the loop flag, the sample jumps to the loop end position upon reaching the loop start (ie. you do not need to reverse the loop start and end values when you play the sample in reverse). PLAYMODE_BIDIR When used in combination with the loop flag, causes the sample to change direction each time it reaches one of the loop points, so it alternates between playing forwards and in reverse.
