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.

Modernization of the legacy vJoy-based RIO cockpit interface for Win10/11,
removing the vJoy dependency in favor of a custom VHF/UMDF HID driver,
rewritten in C#/.NET 8 as a background tray app with per-game profiles.
- Reorganize: legacy C++ -> legacy/, cockpit art -> docs/reference/
- RioJoy.sln: src/RioJoy.Core (lib) + src/RioJoy.Tray (tray app), net8.0-windows x64
- driver/ placeholder for the RioGamepad WDK driver
- docs/PLAN.md (7-phase plan; profiles + serial-yield model)
- docs/PROTOCOL.md (RIO wire format + iRIO input-map reference)
