Downloads and starting firmware

Use bb1-2.0.fwsc together with the matching bb1-sounds-1.4.bin. The source archive and browser corresponding-source ZIP are included. SHA256SUMS pins all four downloads.

The prepared BB1 installer admits corrected BB1 1.5 (FM-1_92200105) or this exact 2.0 identity (FM-1_92200200). Do not assume a different firmware family or an old FM-1_900 package is interchangeable. Back up material before switching firmware; scene compatibility and byte preservation are separate questions. Earlier releases remain available for rollback.

Known issue and verification scope

This release is published at the owner's direction with one known native audio deadline overrun deferred to a minor follow-up: a callback took 6,031.5 microseconds against a 5,802.667 microsecond deadline, recording one deadline exceed and one DMA miss. Later separate bounded runs were clean; they do not explain the original event or prove uninterrupted playback under every workload. A glitch remains possible.

The native build and package are independently reproduced. The corrected SONG/audio/navigation checks and the website's 969-test suite pass at their documented scopes. App-only installation and return to corrected 1.5 passed with two byte-identical readbacks of app, user and both sound regions. The matched-library return is now proven: original1.2 sounds and corrected1.5 firmware were restored, followed by2.0 and library1.4; two full readbacks at each endpoint matched the fresh saved-data reference and unchanged regionB. Formal whole-stack acceptance and exhaustive physical/persistence qualification are not represented as completed passes. These limitations remain disclosed; publication does not convert them into test results.

The measurement/profiling firmware is not part of this release. The playable 2.0 emulator already exists; browser results are separate from physical FM-1 timing. Licence and source notices remain included; no proprietary toolchain is redistributed.

Guide correction (2 November): the live manual and revised downloadable guide now link to the 2.0 browser player. Checksum: bb1-guide-2.0-r2.sha256. The original guide ZIP is retained; firmware, sounds and emulator code are unchanged.
