Summary: ZAK256: Missing opcode 02/82

Initial Comment:
This opcode is used for audio CD commands.

Here is what to do:

r is the result
b is the parameter

b == 0:
  if an audio track is playing: r = 0
  else: r = 1

b == FF:
  I don't know what it's used for, but anyway it's never 
used in the scripts.

b == FE:
  if an audio track is playing: r = the SO block number
  else: r = 0

b == FD:
  pause the audio track
  r = anything

b == FC:
  unpause (start where it was when you paused)
  r = anything

b == a CD track number:
  r = track length in seconds

To check scummvm returns the right track length you 
can look at the global script #9 (0x888A in 49.LFL).

FD and FC are used to let the game load several 
resources without hanging when a CD track is playing. I 
guess it's already not a problem in scummvm :)
