======  Shogo: Mobile Armor Division ======

===== Install the game =====

To install the required util :
<code>
# apt-get install patchelf
</code>

To install the game, mount your CD & run the installer with ''linux32'' from the ''util-linux'' package :
<code>
# mount /dev/cdrom /media/cdrom
$ cd /media/cdrom
$ linux32 ./setup.data/bin/Linux/x86/setup
</code>

===== Register the game =====
The file ''client'' is "//encrypted//" (I didn't spend time on this, maybe it's trivial to bypass, maybe not) ; and we need to combine the provided tool with our cdkey to get a usable binary.

The hard part in today's world is to get the required libraries to run that tool. We need GTK1.2 compiled for i386.

After that it's easy:
<code>
./registergui client
</code>

===== Hack hack hack =====

Patch the binaries to use (system provided) SDL1.2 instead of the bundled SDL1.1 
<code>
patchelf --replace-needed libSDL-1.1.so.0 libSDL-1.2.so.0 cdaudio.dll
patchelf --replace-needed libSDL-1.1.so.0 libSDL-1.2.so.0 client
patchelf --replace-needed libSDL-1.1.so.0 libSDL-1.2.so.0 shogolauncher
rm libsmpeg-0.4.so.0 libfreetype.so.6 libSDL-1.1.so.0
</code>

Bypass the anti-copy protection:
<code>
mkdir custom files
truncate -s 207618048 files/data.tgz
</code>

===== Replace the startup script =====
Replace the provided startup script ''shogo'' with this one:
<code>
#!/bin/sh
export SHOGODIR="$PWD"
export SHOGO_MOVIEPATH="$PWD/Movies"
export SHOGO_CDROM="$PWD"

if ! test -d ~/.hyperion ; then
    echo Creating directory ~/.hyperion
    mkdir ~/.hyperion
fi

if ! test -d ~/.hyperion/Shogo ; then
    echo Creating directory ~/.hyperion/Shogo
    mkdir ~/.hyperion/Shogo
fi

if ! test -e ~/.hyperion/Shogo/autoexec.cfg ; then
    echo Creating default autoexec.cfg file
    echo '"MaxFPS" "30"' > ~/.hyperion/Shogo/autoexec.cfg
    cat $SHOGODIR/autoexec.cfg >> ~/.hyperion/Shogo/autoexec.cfg
fi

if ! test -e ~/.hyperion/Shogo/ShogoLauncher.ini ; then
    echo Creating default settings file
    cp $SHOGODIR/ShogoLauncher.ini ~/.hyperion/Shogo
fi

if ! test -d ~/.hyperion/Shogo/Save ; then
    echo "Creating Save directory"
    mkdir ~/.hyperion/Shogo/Save
fi

cd $SHOGODIR

if ! test -e $SHOGO_CDROM/files/data.tgz ; then
    ./messagebox "  Please mount the Shogo CD-ROM  " "OK"
    exit
fi

cmdline=`./shogolauncher --inidir ~/.hyperion/Shogo --shogodir $SHOGODIR $@`

if test -z "$cmdline" ; then
    exit
fi

export MESA_EXTENSION_MAX_YEAR=2002
export _ _GL_ExtensionStringVersion=17700

eval "$cmdline"

unset LD_PRELOAD
unset _ _GL_ExtensionStringVersion
unset MESA_EXTENSION_MAX_YEAR

rm >/dev/null -f /tmp/*.dll /tmp/*.lto

===== Prevent a game crash =====
''./client: symbol lookup error: ./client: undefined symbol: set_new_handler__FPFv_v''

This is due to a change in ''libgcc'' that broke some binaries that where compiled with gcc 2.95 in an unusual way (like compiling C++ code with ''gcc'' instead of ''g++'').

==== Option a ====
You can use a little [[https://github.com/twolife/lokishim|shim]] that add back functions required by a bunch of old games like this one. 

<code>LD_PRELOAD="/path/to/lokishim.so" shogo</code>

==== Option b ====
The missing function can be found in a //very// old ''libstdc++'', and you can use ''libstdc++-3-libc6.2-2-2.10.0.so'' from [[https://www.improbability.net/loki/loki_compat_libs-1.5.tar.bz2|https://www.improbability.net/loki/]]

<code>LD_PRELOAD="./libstdc++-3-libc6.2-2-2.10.0.so" shogo</code>
