thats great thanks
and i'd love to do it that way but errmmm how !
Good question.... ;-)
1) In your (Mamewah) mame.ini file, set 'general_app_commandlines c:\wincab\wincab.exe' (or whatever)
2) Back in your Mamewah ctrlr file, set LAUNCH_APP_1 "DIK_ESCAPE"
Note if you use Escape above, you will need to remap EXIT_TO_WINDOWS to something else.
Also note this will only work when your Mame list is selected, UNLESS you repeat step 1 for each of your emulator.ini files.
Hope that helps!
