I've added a Search Engine to the application. Now, users can search for files from within the Selected System based on the ROM filename. If the Selected System is based on MAME, it will also search based on the ROM description of each file.
Additionally, I've updated the mame.xml to the latest version.
I've also improved the launch error message. Now, users can see details about the error.
Before updating, please remember to back up your existing system.xml, or it will be overwritten by the default system.xml included in the zip file.
