[ST] NeoST 0.6

NeoST 1/09/2026

• MegaSTE validated on the Field Service bench — the diagnostic cartridge's Q suite
• passes 12/12
• MIDI studio. Input now clocks at a real 31250 baud — the ACIA pulls bytes on a
• scheduler event instead of receiving one burst per frame (×20 throughput, 92% of a real cable). 
• Networking. CAB browses theoldnet.com from the GUI; EtherNEC (ROM3/ROM4 windows fixed) and the Slirp backend pass 5/5.
• Accuracy. Blitter-stolen cycles advance the timer clock; the FDC FIFO flush stalls the CPU at Hatari's exact rate; a halted 68000 says so; the med-res left border removal is fixed. Closure and a generated Spectrum 512 test join the pixel tier, and three demo references moved off Atari ROMs.
• Interface. Per-port Input page, clickable ST keyboard, per-source audio mixer, desktop/kiosk toggle from the keyboard.

Known limitation

• The macOS .dmg is neither signed nor notarised and the Windows .zip is not signed.
• Gatekeeper will report "NeoST is damaged". Until notarisation, clear the quarantine flag: xattr -dr com.apple.quarantine /Applications/NeoST.app
• NeoST-0.6-macOS-universal2.dmg was re-uploaded. The original build carried no bundle signature at all — only the ad-hoc signature the linker puts on the Mach-O binaries, with the Info.plist unbound and no sealed resources — so a downloaded copy was reported by macOS as damaged, with no way to open it short of a terminal command.
