+\subsection{Multi-CD Games}
+In general, ScummVM does not deal very well with multi-CD games. This
+is because ScummVM assumes everything about a game can be found in one
+directory. Even if ScummVM does make some provisions for asking the
+user to change CD, the original games usually install a small number
+of files to hard disk. Unless these files can be found on all the CDs,
+ScummVM will be in trouble.
+
+Fortunately, ScummVM has no problems running the games entirely from
+hard disk, if you create a directory with the correct combination of
+files. Usually, when a file appears on more than one CD you can pick
+either of them.
+
+These instructions are written for the PC versions (which in some case
+is the only version) of the games. Windows and DOS use
+case-insensitive file systems, so if one CD has a file called
+MONKEY.DAT and another has a file called monkey.dat, they are the same
+files. These instructions give file names in all lower-case names,
+even if that's not always how they appear on the CDs. In fact, on
+case-sensitive file systems you will have to make sure that all
+filenames use either all upper- or all lower-case letters for ScummVM
+to be able to find the files.
+
+The instructions for the Broken Sword games are for the Sold-Out
+Software versions, which are the ones you are probably most likely to
+find in stores now.
+
+
+\subsubsection{The Curse of Monkey Island}
+For this game, you'll need the comi.la0, comi.la1 and comi.la2 files.
+The comi.la0 file can be found on either CD, but since they are
+identical it doesn't matter which one of them you use.
+
+In addition, you'll need a resource subdirectory with all of the files
+from the resource subdirectories on both CDs. Some of the files appear
+on both CDs, but again they're identical.
+
+\subsubsection{Broken Sword 1}
+For this game, you'll need all of the files from the clusters
+directories on both CDs. You will also need the speech.clu files from
+the speech directories, but since they are not identical you'll need
+to rename them speech1.clu and speech2.clu for CD 1 and 2
+respectively.
+
+In addition, you will need a music subdirectory with all of the files
+from the music subdirectories on both CDs. Some of these files appear
+on both CDs, but in these cases they are either identical or, in one
+case, so nearly identical that it makes little difference.
+
+ScummVM does not support the original cutscene files, so there is no
+need to copy them.
+
+\subsubsection{Broken Sword 2}
+
+For this game, you'll need all of the files from the clusters
+directories on both CDs. (Actually, a few of them may not be strictly
+necessary, but the ones that I'm uncertain about are all fairly
+small.) You will need to rename the speech.clu and music.clu files
+speech1.clu, speech2.clu, music1.clu and music2.clu so that ScummVM
+can tell which ones are from CD 1 and which ones are from CD 2. Any
+other files that appear in both cluster directories are identical. Use
+whichever you like.
+
+In addition, you will need the cd.bin, cd.inf and startup.inf files
+from the sword2 directory on CD 1.
+
+ScummVM does not support the original cutscene files, so there is no
+need to copy them.
