HalfNES 057

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 v0.56

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.
