It isn't infrequent to see threads started because someone is unable to get an emulator to work or function correctly via the GameEx front-end. Below are the questions in the order the user needs to answer prior to posting that your emulator or ROM XYZ will not work or function as expected: - Does it work within the emulator as expected? Check via the emulator GUI that configs/options/settings to ensure paths and settings for behavior are correct. - Does it support/work as expected via command line? Same as above and will need to research command line settings from emulator's forums, read me or help texts and test from DOS prompt via cmd.exe (if using Vista/Windows 7, you may need to "Run as Administrator.").
Finally, if all working properly in answer to the two questions above... - Has the emulator been properly configured via Setup Wizard in GameEx? If not, refer to the Links to Emulators, Suggested Command-Lines, and MAP files thread in addition to setting up the emulator ROM, images, and other required paths via Setup Wizard.
We will probably ask for you to provide a copy of your log.txt file (located in \gameex\log\ folder), gameex.ini (located in the \gameex\config\ folder), and/or a copy of your emulator configuration (this can be obtained and exported via the Setup Wizard). Refer to the "How to ask for Help" thread for more details.
We will gladly assist you, however, please be prepared to do some homework on the emulators you opt to use and patiently answer a lot of questions.
