New Features - Debugger: General improvements as well as new features/tools (and bug fixes.) - NSF: Allow rewinding during NSF file playback and fixed an initilization problem with VRC6 audio - History Viewer: Added a few new features and options, including allowing it to be used with NSF files - Video: Added support for 512-color palette files (for color bit emphasis.) - Input: Added options to configure the deadzone size for analog sticks and to hide the mouse cursor when using a zapper - Dip switches: Dip switches can now be configured for all cartridges that use them (instead of being limited to VS System games.) Bug Fixes - APU: Fixed frame counter bug that caused audio to sometimes be paced slightly incorrectly - APU: Fixed DMC power on state to match hardware test results - PPU: Prevent palette updates during horizontal blank when rendering is enabled (to match expected hardware behavior.) - Namco 163: Fixed problems with battery save data - Bandai FCG: Added support for EEPROM save data - MMC5: Fixed incorrect attribute data when using fill mode - VRC7: Updated audio instrument values to match the values recently dumped from hardware - AOROM: Fixed power on mirroring state - Misc: Fixed minor bugs in a variety of mappers (including mappers 112, 176, 320 and UNROM512.)
