When Arhu gives you the Sparkmaster 5000 Universal Controller, it felt to me like the ultimate objective was to keep it functional, but no longer a threat to the living. Thus a mad experiment was born: To throw the manual away and try every single code in the hope of a hidden option.
In the below, A = Angry, S = Sleepy, H = Happy
(I wrote the table before looking at the dialogue, hence the order is wrong - sorry!)
AAA - Controller deactivated (controller stops working)
AAS - Self-destruct (dies instantly, no big explosion)
AAH - NOTHING
ASA - NOTHING
ASS - NOTHING
ASH - NOTHING
AHA - Berserk (gains status berserk)
AHS - NOTHING
AHH - NOTHING
SAA - NOTHING
SAS - NOTHING
SAH - NOTHING
SSA - NOTHING
SSS - NOTHING
SSH - Weapons de-activation (gains status weak)
SHA - NOTHING
SHS - NOTHING
SHH - NOTHING
HAA - NOTHING
HAS - NOTHING
HAH - NOTHING
HSA - NOTHING
HSS - NOTHING
HSH - NOTHING
HHA - NOTHING
HHS - NOTHING
HHH - Party mode (skips a turn)
Sadly, there does not currently seem to be any hidden modes
Despite the failure of the experiment, I'm publishing the results anyhow, as I couldn't seem to find anyone else having tested them all. And who knows, maybe I'll be proven wrong
thanks for the experiment. Hope someone will mod this to add something fun
