HalfNES v0.018 Changelog:
Timing fixes - Kid Icarus, Solomon's Key, Adventures of Lolo 2, Jackal are now playable.
Fixed a couple issues with the audio as well.
(Periodic noise works, and channels don't buzz when the periods are set to zero.)
Mega Man 2 is where this improvement is most noticeable.
The OS default look and feel is used instead of the Java default now, which
means the Open dialog is improved.
Saved games should always save on close now, no matter how the window is closed.
