Instead use Name, implementation in RomTools_Common and it is kept as a global in rom.c Also clean up code and use one unified place to read the internal name of the game Do a Coiniitalize(NULL) and Coinitialize before/after calling SHBrowseForFolder in RomBrowser, should already be initialized but it seems to not be... Some general cleanups here and there, format changes using Microsoft tool and some squashed warnings
