Yet again, a new update for the beta version of this open source NES emulator for Windows is available.
Today's build adds some minor tweaks to PPU and APU timing to match certain behaviors observed on the real hardware.
Those of you familiar with Blargg's emulator test ROMs will now observe that it passes nearly all of them (aside from power-on palette and MMC3A/MMC3B behavior).
