tx4io
Open tools for Taito arcade I/O on ordinary PCs: the
Type X4 USB IO board and the
Type X2 / X3 Fast I/O PCI card. One self-contained binary turns either board into a keyboard, Xbox 360 pads or a JVS I/O board, and can flash the USB IO board's firmware. No Taito DLLs are needed, and Fast I/O works natively on Linux.
Status: everything has been tested against simulated boards and unit tests, not yet on real hardware. Reports from real cabinets are very welcome.
Features
Type X4 USB IO board (Taito "USB IO P.C.B.", VID 0AE4 / PID 0901)
- Reads all 56 digital inputs, 8 analog channels, 4 encoders and 2 coin counters; drives 44 outputs and 12 PWM channels.
- Bridge modes: keyboard (MAME keys), Xbox 360 pads (XInput, works with Steam/SDL/Wine/Proton) and an emulated JVS I/O board on a serial port, at the same time if you like.
- Per-game profiles for Street Fighter V, Magician's Dead, Love Live! School idol festival AC and Densha de Go!!, and learn to map any wiring by pressing each control once.
- Full G1/P1 connector pinout from Taito's wiring diagrams, including which output drives which lamp pin, and out --walk to check it.
- Firmware flashing over USB, the same way Taito's game DLL does it, plus .dat inspection and building. An interrupted flash can be rerun over USB.
- Speaks both known firmware layouts: SFV's 0102 and Love Live's 0032 (detected automatically).
- No driver to install on Windows (the board asks for WinUSB itself).
Type X2 / X3 Fast I/O (Oki "iDMAC" PCIe card, PCI 1021:0F10)
- Replaces FastIO2KB: up to 4 players to keyboard, Xbox pads or JVS.
- No iDmacDrv64.dll needed. On Windows tx4io talks to Taito's kernel driver directly.
- Native Linux support with no driver at all: tx4io maps the card's PCI registers through sysfs.
- Register tools (fastio dump --watch, read, write) to finish mapping analog inputs, coins and lamps.
Both
- One static binary for Linux x86_64, Linux ARM64 (Raspberry Pi), Windows 64-bit and Windows 32-bit.
- Hold Test + P1 Start for 2 s to switch modes; a TCP/FIFO control channel for outputs and lamps.
- A --sim mode that replaces the board with an editable JSON file, for testing without hardware.
Quick start
# Linux

./tx4io-linux-x86_64 run --mode xinput
# Linux, Fast I/O card
sudo ./tx4io-linux-x86_64 --board fastio run --mode keyboard
# Windows
tx4io-windows-x86_64.exe info
tx4io-windows-x86_64.exe run --mode keyboard

Building
Needs Rust (rustup). build.sh runs the tests and cross-builds all four binaries into the repository root. The Windows builds need mingw-w64 (apt install gcc-mingw-w64-x86-64 gcc-mingw-w64-i686) and the Linux x86_64 build needs musl-to ols. For a quick local build: cargo build --release.
