Sun, 01 Nov 2020 13:28:31 -0800 Michael Pavone Multiplying by zero and shifting by zero are very different. Fixes regression in Overdrive 2
Sun, 01 Nov 2020 12:32:25 -0800 Mike Pavone Fix a regression in sprite rendering that could cause garbage to be displayed on first line

Sun, 28 Jun 2020 21:31:09 -0700 Mike Pavone Fix regressions from most recent address/cd latch change. Need to do more research still, but probably good enough for now

Fri, 15 May 2020 23:39:15 -0700 Michael Pavone Fix regression in Mode 4 support caused by address/cd latch changes
Fri, 08 May 2020 11:40:30 -0700 Michael Pavone Add an event log soft flush and call it twice per frame in between hard flushes to netplay latency when there are insufficient hardware updates to flush packets in the middle of a frame
Sat, 02 May 2020 00:52:21 -0700 Mike Pavone Fix some netplay issues
Fri, 01 May 2020 23:39:45 -0700 Michael Pavone Netplay protocol size optimization

Thu, 16 Apr 2020 22:37:43 -0700 Mike Pavone Admit defeat on the "trying to write CRAM dots while output is null issue" for now and just add a null check
Mon, 13 Apr 2020 20:43:25 -0700 Michael Pavone Don't apply address and cd register changes to the 'live' registers until pending flag is cleared, but do preserve the upper address bits in the latch. Fixes regression in Overdrive 2 while preserving fix to Mona in 344 bytes
Fri, 03 Apr 2020 23:47:17 -0700 Michael Pavone Top bits of address register should be cleared on partial command word write. Fixes Mona in 344 bytes demo

Thu, 27 Feb 2020 18:38:15 -0800 Michael Pavone Make VDP VSRAM capacity respect model selection
Sun, 02 Feb 2020 22:38:49 -0800 Mike Pavone Fix crash in OD2 Titancade scene when border is completely cropped by overscan settings
Thu, 09 Jan 2020 22:27:20 -0800 Michael Pavone Fix crash in 68K debugger from forced VDP frame update when framebuffer is not acquired
Mon, 06 Jan 2020 18:36:36 -0800 Michael Pavone Fix regression in handling of color index 0 in Mode 4. Support Mode 4 in CRAM viewer window
Wed, 09 Oct 2019 23:06:02 -0700 Michael Pavone Wait to reacquire framebuffer so that switching to UI does not require pushing a new frame if it happens in between bottom and top of display
Sat, 21 Sep 2019 20:23:53 -0700 Michael Pavone Fix regression in H32 from fine scroll optimization
Sat, 21 Sep 2019 20:20:03 -0700 Michael Pavone Small optimization to read_map_scroll

Sat, 21 Sep 2019 10:53:51 -0700 Michael Pavone Slightly gross fix for edge case introduced in border cropping change
Mon, 16 Sep 2019 00:45:48 -0700 Mike Pavone Don't render lines that are cropped by overscan. Allows submitting frame earlier when bottom overscan is non-zero which can reduce latency in some cases
Tue, 20 Aug 2019 20:18:27 -0700 Michael Pavone Small optimization to render_normal and a minor bugfix in left border debug register handling
Tue, 20 Aug 2019 07:07:31 -0700 Michael Pavone Fix sprite rendering regression introduced by H40 line at a time optimization
