====== Medal of Honor: Allied Assault ======
OpenMOHAA is an open-source reimplementation of the Medal of Honor: Allied Assault engine by EA Games / 2015 Inc. (2002). It is a cinematic World War II first-person shooter where you play as Lt. Mike Powell of the OSS, participating in key battles from the Normandy landings to Berlin. Batocera supports the base game and both expansion packs: Spearhead and Breakthrough.
This system scrapes metadata for the "ports" group(s) and loads the mohaa set from the currently selected theme, if available.
Grouped with the "ports" group of systems.

==== Quick reference ====

  * **Emulator:** OpenMOHAA
  * **Folder:** ''roms/mohaa/''
  * **Accepted ROM formats:** ''.mohaa''

===== BIOS =====
No OpenMOHAA emulator in Batocera needs a BIOS file to run.

===== ROMs =====
You need the original Medal of Honor: Allied Assault game data files. We recommend getting the **Medal of Honor: Allied Assault War Chest** from [[https://www.gog.com/en/game/medal_of_honor_allied_assault_war_chest|GOG.com]], which includes the base game and both expansion packs.
Copy the game contents into ''/userdata/roms/mohaa/''. Then create an empty file with a ''.mohaa'' extension in the same directory.

==== Game version detection ====
The game version is auto-detected based on keywords in the launch file name:

^ Launch file keyword ^ Game version ^ Data directory ^
| (default) | Allied Assault | ''main/'' |
| "spear" | Spearhead | ''mainta/'' |
| "break" | Breakthrough | ''maintt/'' |

<WRAP center round important>
Name your launch files accordingly, e.g. ''Medal of Honor - Allied Assault - Spearhead.mohaa'' must contain "spear" for Spearhead to be detected.
</WRAP>

<WRAP center round tip>
These games are ideally designed to be played with a mouse and keyboard. A gamepad controller mapping is however provided for controller use.

===== Troubleshooting =====

==== My game does not launch ====
  * Make sure the ''main/'' folder exists and contains the ''.pk3'' files from your game installation.
  * For expansion packs, verify that ''mainta/'' (Spearhead) or ''maintt/'' (Breakthrough) folders are present.
  * Make sure the launch file name contains the correct keyword ("spear" for Spearhead, "break" for Breakthrough).
