Here is how I got Star Wars: Battlefront 2 Wine Patch installed with Daniel Santos' help. I first installed Wine 1.8 which setup it's default stuff. (The compiled Wine references the .wine archive and settings there. I couldn't find Wincfg in the compiled program so used the system wine to do configurations. The biggest thing for me was needing to set Pulseaudio because once SW: BF2 was launched it wouldn't detect audio unless I set Pulseaudio. In addition, you need to change the game's sound settings to use Software Emulation than Hardware. As maps wont have sound but the menus will.) I then installed PlayOnLinux and used it to install Steam. I IGNORED the PoL SW: BF2 installer and went straight to Steam. Once in Steam I then downloaded SW: BF2. While that was downloading, I did the following:

// Optional  --   sudo apt-get install alsa-base alsa-tools alsa-tools-gui alsa-utils alsa-oss 

1.  wget https://dl.winehq.org/wine-builds/Release.key
    sudo apt-key add Release.key
    sudo apt-add-repository 'https://dl.winehq.org/wine-builds/ubuntu/'
                        OR
    Make sure to add or uncomment the sources URIs in /etc/apt/sources.list


2.  sudo apt-get update


                    [  64BIT  ]
3.  sudo apt-get install flex bison gcc-multilib g++-multilib wine-devel \
                                libx11-dev libfreetype6-dev libasound2-dev

                        OR

                    [  32BIT  ]
    sudo apt-get install flex bison gcc-multilib g++-multilib wine-devel \
                 libx11-dev:i386 libfreetype6-dev:i386 libasound2-dev:i386

4.  git clone https://github.com/daniel-santos/wine
5.  cd /the/location/of/wineBuildDir/
6.  mkdir -p bin/{wine32,wine64}
7.  git checkout hybrid-sync


IF above is done already, to update code do...
git fetch
git reset --hard origin/hybrid-sync

---   Out of tree build   ---
//  Building out-of-tree simply involves invoking configure
//  from an empty directory other than the top of the source tree.
//  Notes:
//      The project must be enabled for out-of-tree builds, typically with the user of VPATH if using make
//      The source tree should be clean (i.e. no build should be done in the original source directory),
//      otherwise it will confuse make

[  32BIT OR 64BIT BUILD  ]
cd /build//wine32
cd /build/wine64

CFLAGS="-m32 -O2" ../../configure    // Note: -02 means use compiler optimize
                                     // level 2 && -00 means no optimization
                                     // -03 I think is the highest.
                                     // --with-wine64=../64 (any other arguments)
                                     // -m32 means do 32bit build



9. make -j     // Hyperthreading doubles your core count so take note.


10. cd loader/


11.  make install    // Optional since we can run from the build dir.

Examples for 32bit & 64bit launch:

WINEDEBUG=fixme-all STAGING_SHARED_MEMORY=1 STAGING_SHM_SYNC=1 WINEPREFIX="/home/abaddon/.wine"  ./wine64 "C:\Program Files (x86)\Steam\Steam.exe" -no-cef-sandbox
