I too am having trouble installing Escape from Monkey Island (EFMI).
I followed exactly the same instructions as described MikeE.
Currently I have a folder called "MONKEY_4" which contains:
files that are m4b (contained in a folder called "files.m4b")
a folder which contains the movie files called "Movies"
a folder which contains all the texture stuff called "Textures" (with renamed files as described by MikeE)
*MonkeyUpdate is in files.m4b, downloaded from here: http://demos.residualvm.org/patches/?C=D;O=A
(Through this link I downloaded the first MonkeyUpdate)
Whenever I try selecting "MONKEY_4" with the ResidualVM program it does not detect it. I presume I have not put everything in, but I did check.
I checked everything from "MonkeyData" (The folder present in both EFMI discs that is contained in a folder called "Monkey4" and "Monkey4" also contains folders "DirectX" and "MonkeyInstall") that was present in Disc 1 and Disc 2.
Based on descriptions from other people on the forum, I assumed this was all I had to do.
I am not very good with computers, so any explanations to this question should bare that in mind.
Currently using ResidualVM 0.2.1
Why is my EFMI not working?
