All passwords for Archimedes Lemmings - *MAJOR SPOILER*
r...@and.cs.liv.ac.uk
---------------------------------
WARNING: This is a *major* spoiler posted by Richard K. Lloyd for those people
who have the full version of Lemmings for the Archimedes. Please skip the rest
of this posting if you don't want to cheat at Lemmings.
How they were obtained
----------------------
Run !Lemmings OUTSIDE of the Desktop (*Gos then *!Lemmings) and then double-
click on "Exit to Desktop" when the main menu comes up. Foolishly, Lemmings
does NOT wipe its workspace when it exits. I then looked for "Your access code
for level..." message (located at &18C64) and worked out that there was
probably a reference to the part of the string which is replaced by the
password (located at &18C89 and originally set to "DavidJones", which DOESN'T
work as a password :-) ). A simple hex memory search found it at &177CC and
then trivial disassembly around there found the base address of the passwords
(located at &18DE0) and that they needed 65 added to them to be visible. Very
easy indeed - I wonder if the extra levels disk will be as simple as this ?
Here they are - the Lemmings passwords

Completing level 30 on Fun, Tricky or Taxing difficulty will simply give you
the password for level 1 on the next highest difficulty. However, the following
message will be displayed when you complete Mayhem level 30 (and, yes, they've
spelt "Everybody" wrong !):
Congratulations!
Everbody here at Krisalis salutes you
as a MASTER Lemmings player. Not many
people will complete the Mayhem levels,
you are definitely one of the elite.
Now prepare to receive rapturous
applause from all here.
Watch out for the new level disks soon!
Two other general passwords
---------------------------
LEMSATSHOW (Disables "Return to Desktop" - for use at computer shows)
IAMNOTGOOD (Allows you to skip to levels using the space bar)
Poor Lemmings coding ?
----------------------
* There appears to be a BUG in the code to handle the level-skip password
("IAMNOTGOOD"). If you use that password and then jump to Mayhem level 30
(using the "LEMMGFINAL" password) and then press space bar to skip the level,
it should finish the game there and then, but it DOESN'T ! It stays at that
level 30, but renumbers it from 1 again (2, 3, etc if you use space bar to
skip levels again) with a difficulty of "Blue" (??!!) and the right-most big
lemming in the main menu holding the skill level icon ends up holding the
WRONG icon (the music icon to be precise).
* Shaun Hollingworth, who wrote the Archimedes version of Lemmings, appears to
have a very strange way of implementing BL routines:
STMFD R13!,{PC}
MOVNV R0,R0
B address
next instruction after routine return
.address routine goes here
LDMFD R13!,{PC}
Anyone care to comment on this and why "BL address" wasn't used instead ?
* When you press left button to play the same level again (after failing to
complete it), why does the level data have to be reloaded from disk again ?
* If I have 2 or more megabytes of RAM, why is this not used by Lemmings to
load all the levels in at once ? If that would take too long, then why not
all the levels of one particular difficulty at once ? This is a VERY common
complaint with most games on all types of machines - they don't use the
extra memory AT ALL !
* ESCAPE should allow you to go back up one menu level (and should return to
the Desktop from the main menu), but only seems to be used to finish the
current level early.
* Although the current difficulty is shown on the main menu, the current level
is NOT - you have to select "Start Game" (accompanied by wasteful disk
activity of course) to find that info out.
* Lemmings can clean up and exit to the Desktop, so this begs the question as
to why it couldn't be installed as a Wimp application with its own icon bar
icon ! Ho hum, it looks like another Desktop Zarch-style hack might be in
order :-)
Anyway, have plenty of New Year fun with these passwords !

The most likely advantage in coding a subroutine call in this way is
to free up a precious register (R14) which would otherwise be
clobbered by the BL instruction storing the return address.
