+# Bink 2 bridge
+
+Demon's Souls plays Bink 2 (.bk2) files through a Bink implementation linked
+directly into eboot.bin. It does not use libSceVideodec, therefore an HLE video
+decoder cannot observe or replace those frames.
+
+SharpEmu observes successful guest .bk2 opens and, when a Bink bridge is
+available, presents its decoded BGRA frames at the normal guest-flip boundary.
+This preserves the game's own timing and lets the host Vulkan presenter display
+the movie without trying to execute the PS5-specific Bink GPU decode path.
+
+Without an adapter, Bink movies are skipped by default: their open call returns
+not-found so games that mark cinematics as optional progress to their next
+state instead of waiting on an empty Bink GPU texture.
+
+Set SHARPEMU_BINK_MODE=dummy to retain the open and show a built-in,
+non-decoded placeholder frame. This requires no SDK, but is a visual diagnostic
+only; it does not decode the movie or alter its game logic. Set
+SHARPEMU_BINK_MODE=native to force native bridge mode.
+
+## Supplying the adapter
+
+Bink 2 is proprietary. Obtain a compatible Mac Bink 2 SDK from RAD Game Tools,
+then compile sharpemu_bink2_bridge.c against the SDK's bink.h and Mac library.
+The adapter deliberately contains only a three-function C ABI so the managed
+emulator never depends on RAD's private binary ABI.
+
+Place the resulting libsharpemu_bink2_bridge.dylib next to the SharpEmu
+executable, or point to it explicitly:
+
+    SHARPEMU_BINK2_BRIDGE=/absolute/path/libsharpemu_bink2_bridge.dylib \
+      ./SharpEmu /path/to/eboot.bin
+
+The expected exports are sharpemu_bink2_open_utf8,
+sharpemu_bink2_decode_next_bgra, and sharpemu_bink2_close. The supplied
+adapter opens one movie, exposes BGRA pixels, and advances after each decoded
+frame. The managed side validates dimensions and retains ownership of the
+destination buffer.
+
+If the bridge is absent in native mode, SharpEmu logs one informational line
+and retains the existing guest rendering path.

+## Release Script
+
+SharpEmu releases are prepared and published using `scripts/release.py`.
+
+The release process consists of two steps:
+
+1. Prepare the version bump through a pull request.
+2. Create and push the release tag after the pull request has been merged.
+
+### Preparing a Release
+
+Run:
+
+```bash
+python scripts/release.py prepare 0.0.2-beta.2
+```
+
+This command will:
+
+- Verify that the working tree is clean.
+- Update the local `main` branch.
+- Create a new branch named `release/0.0.2-beta.2`.
+- Update `SharpEmuVersion` in `Directory.Build.props`.
+- Create a version bump commit.
+- Push the release branch to the remote repository.
+
+Afterwards, open a pull request from:
+
+```text
+release/0.0.2-beta.2
+```
+
+into:
+
+```text
+main
+```
+
+### Publishing a Release
+
+Once the pull request has been merged, update your local repository:
+
+```bash
+git switch main
+git pull --ff-only
+```
+
+Then create and push the release tag:
+
+```bash
+python scripts/release.py tag 0.0.2-beta.2
+```
+
+This command will:
+
+- Verify that the working tree is clean.
+- Confirm that `Directory.Build.props` contains the requested version.
+- Create an annotated Git tag (`v0.0.2-beta.2`).
+- Push the tag to the remote repository.
+
+Pushing the tag automatically triggers the GitHub Release workflow.
+
+### Version Format
+
+Specify the version **without** the `v` prefix.
+
+Examples:
+
+```text
+0.0.2
+0.0.2-alpha.1
+0.0.2-beta.1
+0.0.2-beta.2
+0.0.2-rc.1
+```
+
+The script automatically prefixes the Git tag with `v`.
+
+### Notes
+
+- Run `prepare` only from the `main` branch.
+- Run `tag` only after the version bump pull request has been merged.
+- Do not create release tags manually before merging the version bump.
+- Both commands require a clean working tree.
+- The version in `Directory.Build.props` must exactly match the version passed to the `tag` command.

+/// Pure software implementations of the BMI1, BMI2 and ABM general-purpose-register
+/// bit-manipulation instructions.
+///
+/// The direct-execution backend runs guest PS5 code natively on the host CPU. The PS5's
+/// Zen 2 cores implement BMI1/BMI2/ABM, but a host CPU that predates those extensions raises
+/// #UD (STATUS_ILLEGAL_INSTRUCTION) when it meets one of these opcodes. This class provides the
+/// register-only arithmetic so the exception handler can finish the instruction in software and
+/// resume, instead of aborting the title.
+///
+/// The methods deliberately operate on plain integers rather than on the OS CONTEXT record so the
+/// semantics can be unit-tested in isolation; the unsafe register/memory plumbing lives in the
+/// backend adapter. Each method returns the result already masked to the operand width and, where
+/// the instruction is defined to touch flags, updates <paramref name="eflags"/> in place. Flags
+/// documented as "undefined" by the vendor manuals are left untouched so behaviour stays
