The Scorpion XG-2 Controller was designed to function with arcade emulators such as
MAME ™, and to that end, it is essentially a Plug & Play unit. However, the pre-
programmed keymapping codes do not correspond with the original MAME ™ keycodes,
due to the requirements of the USB Keyboard design structure.
The MAME ™ control options can be reprogrammed using the MAME ™ User Interface
Menu – normally accessed using the TAB key, which then takes you into a series of sub-
menus where you can change the User Interface keys to match your controller, and then
you can change the Player Controls keys to those of your controller. Once programmed
into MAME ™, under normal circumstances, these will remain until you change them.
However if data is corrupted, MAME ™ can default back to the original settings and you
have to reprogram the key settings again which can be frustrating.
However, there is a much quicker way to do this, using the Controller Config options in
MAME ™ and other emulators. Configuration files have been prepared for you, to allow
MAME ™ to load with a default keymap which corresponds to your controller each time it
loads. One of these files is for basic use, where you are using the controller purely for
joystick and button use in your games, and another enhanced configuration file has been
prepared so that analogue controls (Steering Inputs, Pedals, Analogue Joysticks) can be
controlled by your Scorpion XG-2 Controller:
scorpionxg.cfg
-
Standard Configuration File
scorpionxgplus.cfg
-
Enhanced Configuration File
Both of these files are available via e-mail:
or directly
for download on the website:
www.digitalsystemsdesign.co.uk
Controller configuration files should be put into the ctrlr subdirectory of the MAME ™
software folder – eg:
C:\mame\ctrlr\scorpionxg.cfg
When using MAME ™ in DOS mode, the controller config file can be enabled using the
standard controller selection – eg:
mame puckman -ctrlr scorpionxg
If you are using a Front End to interface with MAME ™, then this is usually added in the
emulator configuration folder of your front end software. For example, using mamewah,
the config data is in the following file:
C:\mamewah\config\mame\mame.ini
The same text can be inserted into the emulator command line option, in the Execution
Settings section, along with your other variables – eg:
emulator_commandline
C:\mame\mame.exe [game] -skip_gameinfo -ctrlr -scorpionxg
