for the record, I'm a noob, so I'll honestly admit I have no idea what I'm talking about rly. Just what others have said.
That being said, I read on a thread on stand alone posts that some emulators weren't able to support loading roms directly, and that they might require some default command line parameters. However, I haven't found any mention of these 2 emulators & what said command line parameters would be, so IDK if that might be the problem.
Also, what's a dependency?
