When a per-game setting is the same as the standard one, it is ignored
and not saved to emu.cfg. However the previously saved per-game setting
wasn't deleted, making it impossible to revert.

Now it actually says something about what exactly it tries to open, also on "cancel" it exits gracefully.
Proposal: instead of checking one thousand return codes, which are easily ignored, I suggest using an exceptions (this part of emulator doesn't require execution speed, so exceptions here would be just fine).
There is no reason to build a configuration file of duplicate settings. The user can acquire the defaults from the config section and only inject the changes into the game section.
