I use MAMEWah to start my MAME, DOS, and some PC games. I have been generally able to figure how to get it to do what I want, but recently I have had 1 PC game it won't start. I get the message "does not exist in LaunchApplication". I'm trying to figure out what that message means. My impression is that I'm missing something in MAMEWah for that game, but as I compare the files from the games that do start to the one that won't I can't find the difference. If I take the emulator_commandline entry and paste it into the cmd.exe program the game starts normally, so it's not a typo error.
Any ideas specifically what that message means?
