Prepares RioJoy.Core for the net40 (Windows XP) target, which has no
System.Memory, ValueTask, or System.Text.Json:
- IRioTransport and the whole protocol/framing layer now use byte[] +
Task (RioPacket.Payload, PacketParser/Builder, RioChecksum, replies,
AnalogReport, RioHidReport). At 9600 baud Span bought nothing; the
SerialPortTransport bridge copies disappear entirely.
- ConfigStore/OverlayTemplateStore switch to Newtonsoft 13 with the
same conventions (indented, PascalCase, string enums, null-skipping);
verified against the real STJ-written config.json and regions.json
(load + round-trip). System.Memory and System.Text.Json packages
dropped.
275 tests green.

Retargets RioJoy.Core/Overlay/Tray + tests from net8.0-windows to net48 so
the app can be tested as a framework-dependent build (relies on the in-box
.NET Framework 4.8 on Windows 10/11). Builds clean; all 241 tests pass.
Polyfills (no behavior change):
- PolySharp source generator for init/records/Index/Range/required members.
- System.Memory, System.Text.Json, Microsoft.Bcl.HashCode,
System.Threading.Channels (tests) NuGet packages.
- Compat/Net48Polyfills.cs: GetValueOrDefault, KeyValuePair.Deconstruct,
Math.Clamp; tests/TestPolyfills.cs: Task.WaitAsync.
Source adjustments for APIs absent on net48:
- ArgumentNullException/ArgumentException.ThrowIf* inlined to manual guards.
- Convert.ToHexString, Encoding.Latin1, Environment.ProcessPath,
ApplicationConfiguration.Initialize, Enum.GetNames<T>/GetValues<T>,
string.StartsWith(char), string.Split(char, opts), TextBox.PlaceholderText,
PeriodicTimer, Memory-based Stream Read/WriteAsync, array range-slicing.
- Dropped [SupportedOSPlatform] hints (net48 is single-platform).
deploy/build-package.ps1: publish framework-dependent (no self-contained).

Author the custom virtual HID gamepad that replaces vJoy, and pin its wire
format on both sides. Builds clean to RioGamepad.sys against the EWDK
(KMDF 1.15 + VHF, x64, warnings-as-errors).
driver/RioGamepad/:
- ReportDescriptor.h: 6x16-bit axes (X,Y,Z,Rx,Ry,Rz), one 4-direction hat with
null state, and 96 buttons — the legacy vJoy layout. 25-byte input report.
- Device.c/Driver.c: KMDF root-enumerated device that creates the VHF virtual HID
device (VhfCreate in DeviceAdd, VhfStart in D0Entry, VhfDelete on cleanup) and
exposes a device interface + IOCTL_RIO_SUBMIT_REPORT that forwards the caller's
report bytes to VhfReadReportSubmit. Thin relay: no report logic in the kernel.
- Public.h: device-interface GUID, IOCTL, and the report byte layout shared with
the C# client. RioGamepad.inf + build.cmd (EWDK build, catalog/sign disabled).
src/RioJoy.Core/Hid/RioHidReport.cs: packs AxisOutputs + hat + 96 buttons into
the exact 25-byte report (LE axes, hat nibble with 0x0F=centered, button bitmap).
13 new xUnit tests (136 total).
Remaining (deploy-side): test-sign + pnputil install + verify in joy.cpl, and
wire the real DeviceIoControl feeder sink (replacing NullJoystickSink). The
EWDK's in-build catalog task (DrvCat) can't load Microsoft.Kits.Logger on this
image, so the .cat is produced with inf2cat/signtool at install time instead.
