HalfNES v0.036 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 v0.036 Changelog:

-Added Mapper 9 (Punch-Out!!) -Fixed Teenage Mutant Ninja Turtles (leftover bug from last PPU rewrite) -Fixed Jurassic Park (same problem as Twin Cobra, changed the code so both worked) -Increased audio volume -Added greyscale and color emphasis to PPU (Noah's Ark is maybe the only game this is visible in) -Fixed off-by-one error causing scanline 261 to be run twice (fixed some timing issues, maybe caused a few more) -Completely changed the way the PPU renders sprites - broke some games (Guardian Legend and some Codemasters games that never looked right anyway) but fixed screen shaking and single scanline glitches in a LOT of games. -Also, sprite flicker is back from the old days.
