MAME 0.285 import issue

[Junishin]

I keep getting the following error and have no idea how to proceed to fix it. 

Any help would be appreciated. Thank you

What version of mame.exe is your emulator?

[Junishin]

I'm not sure. I selected for it to update the emulator. Should I download it separately and update it manually? 

 

Thank you for your help

I should have also asked what version of LaunchBox are you on?

Since you keep getting the error, I assume you kept retrying the Full Set Import Wizard and kept trying to have LaunchBox install/setup MAME for you. 

At this point, it may be easiest to have you install it yourself.

Look in your /LaunchBox/Emulators/ folder and remove any MAME subfolders.

Check in Tools - Manage - Emulators and see if you have multiple installs there. If so, remove them all.

Now add a New Emulator, start typing in "MAME" for the name. To the right should appear a globe icon.  Click it to go to MAMEDev's site.  Download and install the revision that matches the revision of your MAME ROM set.  The 2 MUST match!  Alternately install it yourself somewhere.  Either way, next point the Application Path to your "new" mame.exe file.  Click OK to save and close.

Start the Full Set Wizard again. When you get to the 'set the emulator', select the Manually Set up... (worded something like that) option.  You'll get a "Warning", click passed it and select the emulator you just installed.  Hopefully this time you won't get the error.

 

The Error:

During the Full Set import, LaunchBox will use your mame.exe along with the parameter "-listxml" top create an xml file of all the games that specific revision of mame.exe emulates.  LB then parses the xml to get all the games' info.  The error is [I believe] indicating there was an error in the xml file.  Possibly got corrupted somewhere along the way.  

 

If you still get the error, report back with your LaunchBox version and the revision (version) of MAME you installed.  Also add a screenshot of the error (if it's not the exact same as in your OP).

I tried deleting the emulator and reinstalling as well as manually installing it. 

Neither worked. 

I downloaded the update roms for 0.285 and left them in their own folder and somehow it seems like this method is not giving me the error. Not sure why.

Thank you for all your help!

That's very odd, because the importer doesn't really "look" at your ROMs other than 'counting' them to see that you have at close to a full set and their location to set the ROM path.  It then uses the xml to get/set all the game names/titles and then import them based on that and the filters you set.

Regardless, well done.  Sounds like it's now working.
