Release 1.7.0

5DO 1.7.0

Released: 2026-11-10

5DO 1.7.0 is the platform and media-polish update. It adds CD subcode/Q data and disc convert, makes the desktop shell focus-aware with selectable void patterns, extends input scripts with pointer devices, closes the native runtime smoke matrix on macOS and arm64, and ships macOS as a drag-to-Applications DMG.

The apps are framework-dependent. Install the .NET 10 Runtime from https://dotnet.microsoft.com/download/dotnet/10.0 first; the bundles do not include it. See the release page for SHA256SUMS.txt.

Highlights

• CD-ROM subcode/Q. READ_DATA returns the 96-byte subcode block with Q packed into bit 6 of each byte (control/ADR, track, index, absolute and relative MSF, inverted CRC-16/CCITT). The CD wire accepts Opera's 2449-byte maximum.
• disc convert. Data-only ISO/BIN/CUE+BIN/flat CHD conversion verifies the output game ID. CHD encoding uses a unique temporary BIN and no longer collides with a same-stem source image.
• CD-ROM state v6. New states preserve the full transfer buffer; v1-5 states still load with their historical 2352-byte data buffer.
• Desktop. Opt-in focus-loss pausing, solid/checker/grid/scanline void patterns, 0RGB1555/RGB565/XRGB8888 frame assembly, and pointer input scripts.
• macOS gamepad input. Native IOKit HID source with a unit-tested mapper for joystick/gamepad/multi-axis controllers.
• Packaging. macOS is published as a DMG. Unsigned Windows/Linux/macOS installer scaffolding registers .iso, .cue, .chd, and .bin associations.
• Platforms. macOS x64/arm64, Linux arm64, and Windows arm64 pass the native CLI selftest and frontend --smoke-test.

Validation

• Full suite 2,124/2,124 passes in Debug.
• Build, format, and InspectCode are clean.
• ISO/BIN/CUE/CHD conversion round-trips every data sector.
• The six framework-dependent bundles contain the apphosts and legal/docs set with no runtime, PDB, or XML files.

Known limits

• Playability follows the binary beyond-title rule, not a full playthrough.
• CD command cadence remains the residual differential on the 50-title panel.
• Windows x64 remains the validated GPU target; Linux GPU presentation is preview/best-effort.
• Physical macOS gamepad detection still needs a macOS host with a connected controller.
• Signing and notarization require a Windows certificate and an Apple developer account.
