sg-unpack

Unpacker for SciADV series .mpk content files.

Although originally written for the Steam edition of STEINS;GATE, sg-unpack is known to work with the following:

Game	Source(s)
STEINS;GATE	Steam, DMM
STEINS;GATE 0	Steam, DMM
STEINS;GATE: Linear Bounded Phenogram	Steam
Chaos;Child	Steam, DMM

Other configurations might also work - including other games using the .mpk format - but these are untested.

sg-unpack does not currently implement the extraction logic required to unpack STEINS;GATE ELITE .cpk files.
