make_patch.py gains --baud31250: one byte beyond the wedge patch — the SCI init operand at $D62B ($30 -> $02). BAUD $30 = /13 prescale, /1 divider (2MHz E / 208 = 9615); $02 = /1, /4 -> 31250 exactly, 3.3x faster. The init write also confirms the 8MHz crystal, which is why 19200/38400 are unreachable and why 62500/125k are left alone pending an ISR cycle count. - 24 bytes changed vs original (sha256 9f866cf3...); re-disassembly diff vs the classic patched image shows exactly the one operand line, and the classic build still reproduces 3fc8170c... (script regression-safe). - PC side: SerialPortTransport takes an optional baudRate (default 9600, runtime untouched); RioSerialMonitor + --mash accept --baud 31250. - Caveats documented in README/ANALYSIS: non-standard rate (FTDI-class adapters only, no 16550s); native games still speak 9600 so this chip is bench/RIOJoy-only; validate the wedge patch at 9600 first. 275 tests green; mash --selftest regression unchanged (FAIL/exit-1).

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 1–5 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 (DeviceIoControl →
RioGamepad.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.iniimporter, 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). Seedocs/PLAN.mdfor the full roadmap.
