This effectively revertsb380514764andc24473ddff, restoring the state at598cd52272. Before pushing, please check that what you're about to push is sane. Check your local commit log and ensure there isn't anything out-of-place before pushing to mainline. When things like this happen, it wastes everyone's time. I really don't need this in a week when real work™ is busting my balls and I'm behind where I want to be with preparing for MAME release.

Multiple Configuration Files
|
|
============================
|
|
|
|
MAME has a very powerful configuration file system that can allow you to tweak settings on a per-game, per-system, or even per-monitor type basis, but requires careful thought about how you arrange your configs.

Order of Config Loading
|
|
-----------------------
|
|
|
|
1. The command line is parsed first, and any settings passed that way *will take
|
|
precedence over anything in an INI file*.
|
|
|
|
2. ``mame.ini`` (or other platform INI; e.g. ``mess.ini``) is parsed twice. The
|
|
first pass may change various path settings, so the second pass is done to
|
|
see if there is a valid configuration file at that new location (and if so,
|
|
change settings using that file).
|
|
|
|
3. ``debug.ini`` if the debugger is enabled. This is an advanced config file,
|
|
most people won't need to use it or be concerned by it.
|
|
|
|
4. Screen orientation INI file (either ``horizont.ini`` or ``vertical.ini``).
|
|
For example Pac-Man has a vertical screen, so it loads ``vertical.ini``,
|
|
while Street Fighter Alpha uses a horizontal screen, so it loads
|
|
``horizont.ini``.
|
|
|
|
Systems with no monitors, multiple monitors with different orientations, or
|
|
monitors connected to slot devices will usually load ``horizont.ini``.
|
|
|
|
5. System type INI file (``arcade.ini``, ``console.ini``, ``computer.ini``, or
|
|
``othersys.ini``). Both Pac-Man and Street Fighter Alpha are arcade games,
|
|
so ``arcade.ini`` will be loaded here, while Atari 2600 will load
|
|
``console.ini`` as it is a home game console.
|
|
|
|
6. Monitor type INI file (``vector.ini`` for vector monitors, ``raster.ini`` for
|
|
CRT raster monitors, or ``lcd.ini`` for LCD/EL/plasma matrix monitors).
|
|
Pac-Man and Street Fighter Alpha use raster CRTs, so ``raster.ini`` is loaded
|
|
here, while Tempest uses a vector monitor, so ``vector.ini`` is loaded here.
|
|
|
|
For systems that have multiple monitor types, such as House Mannequin with
|
|
its CRT raster monitor and dual LCD matrix monitors, the INI file relevant to
|
|
the first monitor is used (``raster.ini`` in this case). Systems without
|
|
monitors or with other kinds of monitors will not load an INI file for this
|
|
step.
|
|
|
|
7. Driver source file INI file. MAME will attempt to load
|
|
``source/``\ *<sourcefile>*\ ``.ini`` where *<sourcefile>* is the base name
|
|
of the source code file where the system driver is defined. A system's
|
|
source file can be found using **mame -listsource <pattern>** at the command
|
|
line.
|
|
|
|
For instance, Banpresto's Sailor Moon, Atlus's Dodonpachi, and Nihon System's
|
|
Dangun Feveron all run on similar hardware and are defined in the
|
|
``cave.cpp`` source file, so they will all load ``source/cave.ini`` at this
|
|
step.
|
|
|
|
8. BIOS set INI file (if applicable). For example The Last Soldier uses the
|
|
Neo-Geo MVS BIOS, so it will load ``neogeo.ini``. Systems that don't use a
|
|
BIOS set won't load an INI file for this step.
|
|
|
|
9. Parent system INI file. For example The Last Soldier is a clone of The Last
|
|
Blade / Bakumatsu Roman - Gekka no Kenshi, so it will load ``lastblad.ini``.
|
|
Parent systems will not load an INI file for this step.
|
|
|
|
10. System INI file. Using the previous example, The Last Soldier will load
|
|
``lastsold.ini``.
|
|
|

Tricks to Make Life Easier
|
|
--------------------------
|
|
|
|
Some users may have a wall-mounted or otherwise rotatable monitor, and may wish
|
|
to actually play vertical games with the rotated display. The easiest way to
|
|
accomplish this is to put your rotation modifiers into ``vertical.ini``, where
|
|
they will only affect vertical games.
