Is there a graphical non-commandline Rommer tool?
Yes! As of XCade 1.4 we include “WinRommer” which is a simple Windows application that does everything the commandline Rommers do. An OSX version of WinRommer will come along shortly! With WinRommer you simply run the tool, pick a game from the listing, type in or select a directory containing the files making up the ROM-set and hit Convert! A new .pdb will pop out in the same directory you run WinRommer (the “current directory” actually) and you simply send that up to the handheld. A screenshot of WinRommer is here.
