NSFPlay v2.2 is released. NSFPlay is an NSF player for Windows and plugin for Winamp. It is a fork of the original program by Brezza, intended to provide support for more recent Windows operating systems, and improve its accuracy and utility.

NSFPlay v2.2 Changelog:
Audio Emulation:
- Unmute on reset now sets $4015 to $0F instead of $1F.
- PAL noise frequency $1 now 8 instead of incorrectly 7.
- New VRC7 patch set, option to select alternative patch sets via VRC7_PATCH.
- 5B polarity inverted, envelope adjusted, volume tweak.
- MMC5 polarity inverted, length counter runs at double speed, highest 8 frequencies are not muted.
- VRC6 $9003 register implemented (controls halt and frequency multiplier)
- VRC6 polarity inverted, phase reset now functions properly.
- FDS now uses NSF header $76/$77 to set up $6000-7FFF memory range.
- FDS $4087 bit 7 now mutes modulator.
- Enable periodic noise option fixed. (Forced perodic noise by accident.)
Other:
- Fixed improper $4015 read implementation (should return length counter status), also DPCM IRQ was not initialized.
- Default focus in keyboard window now the track list (to prevent accidental mouse scroll time expansion).
- Fixed Winamp visualizer timing inaccuracy, changed default keyboard delay/freq.
- Inverted VRC7 volume display in keyboard view.
- NSFe support.
- Added NSFe extension block 'text', contains null terminated string of any length (NSF text).
- Removed broken ENABLE_DCF config option. HPF=256 now correctly disables HPF.
- Rewrote LPF and HPF, should have a more usable range of options now.
- Removed XXX_FR/XXX_FC options, now XXX_FILTER works like LPF for each device.
- Memory R/W access is now exclusive to the first device that accepts it; prevents FDS multi-expansion write conflicts.
- Title string will automatically remove whitespace at its beginning or end.
- Fixed single instance bug, was failing to open new NSF file when chosen from explorer.
- Fixed conflicts between keyboard commands and other dialogs.
- Removed tag menu from info page. Does not appear to apply to NSFs.
- Fixed incorrect PAL pitch when QUALITY=0.
