NeoST v0.6.4 is released. Atari ST/STE Emulator based on Moira.

NeoST Changelog:
The last step before 0.6.5, which will precede the switch to the POM68K 68000 core.
Accuracy
MFP timers now start on their own clock edge, as the MC68901 datasheet says: Lethal Xcess on STE gets its top border back.
The MFP elects interrupts by fixed priority, freezes its counter when stopped and counts the pulse of an AER change in event-count mode.
The ACIA, SCC and WD1772 follow their datasheets on a few remaining points.
Mouse
Drag-and-drop works in games and on the desktop; Chessmaster is now playable.
Games
Lethal Xcess and Golden Axe (STE), Rick Dangerous and Pang (launched from the GEM desktop) join the replays checked against Hatari: 23 in total.
The TOS 2.06 UK double fault on boot with an early SPACE is explained: a real race in the ROM, not an emulation defect.
Verification
The CPU swap gate now replays reference screens, game replays, the whole disk collection (ST, STE, Mega STE) and Mega STE probes at 16 MHz.
The 68000 bench now covers bus errors and double faults against the fx68k RTL.
Four reference screens no longer depend on the boot phase.
The collection and the replays run clean under ASan/UBSan.
Save states: format v59, unchanged since 0.6.3.
Packages ship with their licences (GPL-3.0.txt, GPL-2.0.txt, THIRD-PARTY.txt) and contain no Atari ROM: EmuTOS is the default.
