I'll give it a try and see if I can get it working... UPDATE!: Didn't get it to work at all (Here is my config, what is wrong) # This file allows launching specific MAME roms # With an alternative emulator setup in GameEx # such as an alternate version of MAME or an emulator # that provides faster emulation. # Note: a MAME game list update is required after making changes # here. # This is a registered version feature [GENERAL] # Enable this feature in GameEx and use this file Enabled=True # You may not want to list an emulator specified seperatly # in the GameEx menus # and make this feature transparent. # Specify Emulator Numbers seperated by | to hide and use only for MAME Hide=54 # Some emulators need the full filename of the rom. ie with the .zip extension # Specify emulators where the extension should be used seperated by | Ext= # If you want roms for a specific driver to always be visible in the list # and override any other filters, such as when you dont have the MAME rom # specify the drivers seperated by | Driver= # The following settings tell GameEx when to use an emulator to launch # instead of MAME. To specifcally specify MAME use 0. To specify Daphne # use 1000 # # Example Launches 1942 rom with emulator 10: # 1942=10 # # Example Launch rom lair with Daphne: # lair=1000 # # Specify a list of rom names with an emulator number # to have GameEx launch the rom with that emulator astinvad=54 [MAPROMS] # Map ROMS to an emulator on an individual basis # This overrides any other mappings # If you want to exclude a rom from any of the other mappings # Specify it here as 0 (use MAME) # Specifing a rom and an enabled emulator here will also # ensure it will override all other filters when updating the # game list and always be available. [MAPPROPERTIES] # This matches roms with the specified properties as below Analog=0 Cocktail=0 Vertical=0 Gun=0 Trackball=0 Vector=0 Horizontal=0 [MAPDRIVER] # Specify a list of MAME drivers to map neogeo=0 [RENAME] # When a match is found for a rom, rename it to the following # When passing it to the emulator. The emulator will try to launch the # new name. # # Example: # mrdriller=drill.zip When I run Astro Invader it still runs MAME32UIFX and not MAME32Plus 0.106 config as Emulator 54
