HalfNES v0.038 is released. HalfNES is an open-source emulator for the Nintendo Entertainment System, written in Java. Currently, it only runs as a standalone Java SE application.

Current Features:
-Now cropping off the top and bottom 8 pixels of the video output, since these are
not visible on most TVs and a lot of games render garbage on those lines.
-Added volume slider to options dialog (and rewrote the sound output code as well.)
-Fixed a lot of sound bugs. Crystalis, Zombie Nation, A Boy And His Blob etc. all sound right now.
-Fixed Twin Cobra

HalfNES v0.038 Changelog:
-Added Action 52 mapper (228)
-Improved audio quality some more
-Made the screen repaint even when paused
-Behind the scenes changes to make things easier to port
-Some speed improvements as well
If there is a game that you want to play that's broken or mapper unsupported, let me know!
Otherwise I think I'm just going to port this to Android next.
