I'm using the latest version of UltraMap for my U360, however it seems to be ignoring options passed to it:
From my MAMEwah log file;
c:\program files\ultramap\ultramap.exe c:\mame\ugc\dkong.ugc /errorgui:1
This from my understanding SHOULD display an error message for one second and dismiss it (as there is no "dkong.ugc" file. However, the dialog box remains until I dismiss it. Is there something I am doing wrong?
