First release in 2 years

061 (2/16/2016)

• Minor speed improvements and code cleanups

• Audio output is done in stereo now (though no interface to pan channels)
• Build system changed to Maven

  (It needs more work for desktop use.)

060 (8/29/2015)
-Fixed Battletoads and Battletoads: Double Dragon freezes on certain levels
-Reduced jerkiness of scrolling in 50 fps games
(not eliminated entirely unless your monitor is also set to 50 FPS)

059 (7/28/2015)

• Fixed certain FDS NSFs that wanted to write to bankswitched areas
• Added PAL and Dendy (Hybrid PAL console that plays unmodified NTSC games) support
• Fixed negative scroll values (Galaxian, TMNT)
• Fixed envelope decay for VRC7 sound

Release 058 (6/14/2015)

• Added support for FDS audio chip (for NSFs only)
• Improved loading of NSFs with nonstandard headers (should not crash on POCorGTFO example)
• Made Konami VRC and Sunsoft 5B and FME7 mappers cycle accurate
• MMC5 mapper is a little better
• Fixed games that set negative scroll values (Galaxian, TMNT 1)

Release 057 (7/30/2014)

-PPU is now pixel accurate. Meaning that many glitchy games are now completely
fixed. However it also means that performance is worse.
-MMC3 and MMC5 scanline counters have been rewritten to be more accurate.
Fixed games:
-Marble Madness

-Laser Invasion
-Mickey's Adventures in Letterland
-Rad Racer
-Slalom
-Tiny Toon Adventures (the status bar was off by one scan line before)
-Mega Man 3 (displays same glitchy lines as real hardware)
-Every Namco 163 game (scanline counter was broken)

Also passes several more of blargg's PPU and MMC3 tests.
I haven't fixed all of the MMC3 based multicart mappers yet.

HalfNES Release 056 (7/17/2014)
First release hosted on GitHub.
-Multithreaded NTSC filter for better performance
-Rewrote CPU/PPU timing entirely (passes many timing tests that used to fail)
-Fixed VRC7 feedback (Lagrange Point now sounds almost completely correct)
-Fixed loading of large NSF files.
-Many other minor fixes over the past year.
