Allthough MAMEWAh Setup can create a game list for mame I have only tested it with Command line MAME with the default set up so make sure you have Windows Command Line version of MAME, and put all your ROMS in the rom folder in your MAME dir.
Run MAMEWAh Setup and set the list generation method to 'ROM Folder Vs List Info'.
Now in order to make the list, MAME must be named 'MAME.EXE'.
Set the 'Emulator Executable' to MAME.EXE and the game list should get created automatically with the corect names etc.
You may get asked if you want to add none working games to the list. I can not remember what this does because I started it and then got side tracked doing something else and forgot about it
