Cadence 2.1 18/06/2026

New flow-based floppy drive architecture (FDC-flux): Disk access is handled via TrackFlux, with proper handling of ID-only sectors and framing reconstruction during protection overreads. This improves compatibility with protected disks.

Additionally:

• Real SRT/HLT/HUT timing from SPECIFY
• PPI now latches writes to port A while in input mode

Cadence 2.0 13/06/2026

Cadence nowy emulator Amstrad Schneidera

A major release centered on audio latency and Windows correctness.

Audio

• ~15 ms audio latency (down from ~60 ms): the PSG now streams every sample straight into the audio ring, and the emulator paces in 5 ms slices.
• The Audio → Latency setting now also scales the pacing cushion (Low ~15 ms / Normal ~26 ms / Safe ~52 ms). If you hear clicks on a busy system, step it up one notch.

Windows

• Fixed: disc "Read fail" errors present in every Windows release to date (32-bit overflow corrupted sector timing on half of every track).
• Fixed: emulation running below real speed with a constant low-frequency buzz over sound (systematic sleep overshoot was being forgiven instead of repaid).
• Audio now opens WASAPI (modern Windows audio path) instead of the legacy default.
• Fixed a 32-bit timer wrap that would have disturbed sessions longer than ~36 minutes.

Diagnostics

• About now shows the OpenGL renderer and the real audio path (host API, device, latency, underrun counters) — invaluable for remote reports.
