Dungeon Master hints?

[wsquires@lonestar.utsa.edu (William H. Squires)]

  First question: how to get into the secret room on level 6 behind the wall
in the room about King Milias? I've tried throwing/dropping any and all
treasures here to no effect. I've even tried standing on each of the nine
squares in the room with various combinations of coins. No go. What's the
deal?
  Second question: Is there a Dungeon Master ][ game? Is it available for the
//GS? I have Dungeon Master for the GS, and have tried it on other systems. I
find the GS version to be the best overall. A Dungeon Master ][ game would
be way cool!
  Third question: Are there any easter eggs in Dungeon Master? If so, where?
  BTW: the puzzle referred to in query 1 is the only one I haven't been able
to solve, yet. Also, to the person inquiring about FUL-bombs. There isn't a
spell for this. I've tried ALL the combinations (at full power -- my wizard
has more than enough; about 150 Mana), and not one gave me a FUL bomb! The
spell he/she was thinking of was <power>-FUL-IR which is a fireball. The
only "bomb" you can make is a VEN-bomb (poison-gas). Naturally, it requires
an empty flask. The spell is <power>-DES-IR-SAR (or something like that).
  Also, if any of you have the cracked version of this from Computist (on
3.5" only), don't kill all your characters with a fireball in order to
restart the game; it'll hang the computer.
  There is one easter-egg that I know of (if you have the cracked version)
on level 4. There's a room near the end of the level that contains a bunch
of screamers. Kill them all (without magic), pick up the screamer slices, and
leave; closing the door behind you. Go down to level 5, then go back up again
using the stairs a couple steps down the hall. Press the button (if you
haven't already), then go back into the screamer-room. they'll have regenerated.
Freebie food! I don't think this'll work on a non-cracked version, though. The
steps in question are right near a pit-trap!
