CydandClaude Fable 5 63af7bde01 Phase 8C: RioJoy.Tray multi-targets net48 (x64) + net40 (x86, Windows XP)
The XP flavor keeps the full runtime AND the mapping editor (decided:
editor everywhere). Gated per flavor:
- Wallpaper maker + WallpaperCanvas + generation (SkiaSharp) are
  net48-only; the XP coordinator applies the profile's pre-rendered
  wallpaper instead, and WallpaperApplier converts PNG->BMP on net40
  (XP SPI_SETDESKWALLPAPER accepts only BMP).
- Joystick chain: ViGEm branch compiled out on net40 (HID feeder stays,
  ready for RioGamepadXP.sys); the editor button picker offers the full
  96 HID buttons on net40 vs the 11 named Xbox buttons on net48.

Verified: net40/x86 exe boots on Win10; the editor renders offline in a
32-bit host with a Button-50 joystick binding resolving correctly and
live gauges working (screenshot harness).

RIOJoy

Modern Windows 10/11 interface between the cockpit RIO (Remote Input/Output) board and Windows, as a virtual joystick / keyboard / mouse — the successor to the legacy vJoy-based app, with no vJoy dependency.

The RIO has 72 digital inputs and outputs (lighted buttons) and 5 analog axes (joystick X/Y, throttle, left pedal, right pedal), connected over RS-232 at 9600 8N1. RIOJoy exposes these to games that don't natively know about the cockpit hardware, with per-game profiles. (The native games — Firestorm, Red Planet — talk to the RIO directly and do not use this app.)

Building

Requires the .NET SDK (8.0 or newer) plus the .NET Framework 4.8 targeting/developer pack, on Windows. The apps target .NET Framework 4.8, which is in-box on every Windows 10/11 machine — so deployed builds are framework-dependent and need no runtime install on the target. The driver builds separately with the WDK (see driver/README.md).

dotnet build RioJoy.sln -c Release
dotnet test RioJoy.sln

Status

Phases 15 are implemented and tested (241 unit tests). The RioGamepad virtual HID driver is built (KMDF + VHF), test-signed, installed, and verified: it enumerates in joy.cpl, and the C# HID feeder (DeviceIoControlRioGamepad.sys) drives its axes, buttons, and hat end-to-end (see tools/RioJoySmokeTest). The C# side covers the serial

  • RIO protocol core, input mapping + output routing, axis calibration + plasma display, the tray app + profiles (JSON config, RIO.ini importer, three-state auto-switch), and the HID report packer that matches the driver's wire format. Remaining work is on-cabinet (real RIO serial/axis/plasma/auto-switch verification) plus packaging (Phase 6) and the profile editor + overlay generator (Phase 7). See docs/PLAN.md for the full roadmap.
