The NES emulator HalfNES has been updated.

HalfNES Version Notes:

0.048 (6/5/2012)

You can now change all options without having to restart the emulator. Also
changed the set of values used for the VRC7 registers and did some code cleanups
in various places. Significant rewrite is needed to improve basic timing
accuracy some time soon.
