Fri, 27 Mar 2020 00:03:58 -0700 Michael Pavone Initial stab at VGM logging support
Wed, 26 Feb 2020 22:40:37 -0800 Michael Pavone Implement selectable YM2612/YM3834 invalid status port behavior
Mon, 24 Feb 2020 20:06:29 -0800 Michael Pavone Fix YM2612 busy flag timing
Sat, 07 Sep 2019 22:18:09 -0700 Michael Pavone Cache operator phase increment for a small perf improvement
Fri, 17 May 2019 08:43:30 -0700 Michael Pavone Split generic part of audio code into a separate file so it can be used in other targets besides SDL
Wed, 27 Mar 2019 22:04:54 -0700 Michael Pavone Operator results should be delayed by one sample when used as a modulator in some cases based on relative execution time and pipeline length
Sun, 24 Mar 2019 19:59:41 -0700 Michael Pavone Optionally emulate the offset around zero in the imperfect DAC of a discrete YM2612
Sun, 30 Dec 2018 18:48:08 -0800 Mike Pavone Optimize YM operator modulation
Fri, 30 Mar 2018 00:37:08 -0700 Michael Pavone More audio refactoring in preparation for allowing proper sync to video with dynamic audio rate control
Wed, 28 Mar 2018 23:36:08 -0700 Michael Pavone Small cleanup to audio interface between emulation code and renderer backend
Sun, 06 Aug 2017 00:06:36 -0700 Michael Pavone WIP - New savestate format
Thu, 30 Mar 2017 23:57:30 -0700 Michael Pavone Reset YM2612 whenver the Z80 is reset. Fixes issue with stuck notes in Fantastic Dizzy and Kid Chameleon
Mon, 27 Mar 2017 00:40:10 -0700 Michael Pavone Initial implementation of YM2612 SSG-EG mode
Sat, 25 Mar 2017 15:41:52 -0700 Michael Pavone Basic implementation of CSM mode that should handle documented edge cases. Dodesn't handle the weird undocumented edge cases I don't have a good understanding of yet though
Sun, 01 May 2016 13:36:14 -0700 Michael Pavone Made low pass filter frequency configurable
Wed, 20 Apr 2016 09:18:58 -0700 Michael Pavone Implemented linear resampling and low pass filter for the YM2612
Thu, 18 Feb 2016 21:28:33 -0800 Michael Pavone Remove phase increment caching. Fix LFO phase modulation calculation
Sat, 13 Feb 2016 22:20:37 -0800 Michael Pavone Add yt debug command for printing YM-2612 timer info. Fix AMS shift values.
Fri, 13 Nov 2015 22:56:59 -0800 Michael Pavone Selecting a second game from the menu now works
Sun, 01 Nov 2015 12:55:08 -0800 Michael Pavone Wrote a buggy tool for splitting VGM files by channel
Sat, 31 Oct 2015 21:11:40 -0700 Michael Pavone Small fix to how manual YM-2612 timer reloads work. Seems to better match a small test program and gets audio to match up in TM.EE's "I've got Italo Inside" track.
Wed, 27 May 2015 20:53:21 -0700 Michael Pavone Add a basic YM-2612 command to the debugger. Fix negative detune values and get the correct precision for the multiplication step of phase inc calculation
