This repository contains source code for a Windows console application, fast2kb.exe, which reads input via iDmacDrv32.dll or iDmacDrv64.dll from a Fast I/O Direct Memory Access Controller (DMAC) and remaps this input to DirectInput keyboard events. Any DirectInput-compatible application can receive the remapped input.
For example, on a Windows-based arcade machine with a Fast I/O control system, fast2kb.exe can serve input to a DirectInput-compatible emulator such as MAME or PPSSPP.

- Fast I/O DMAC board and drivers: Tested successfully with:
- Taito Type X2 PCIe board (K91X1209A J9100636A). This device is manufactured by Oki Information Systems and is found in NESiCAxLive and Dariusburst versions of Taito Type X2 arcade machines. Device Manager was used to install a driver package containing

- Fast I/O microcontroller board: Taito boards with the designation J9100634A (having a JAMMA edge) or J9100633A (not having a JAMMA edge) are believed to be compatible. Tested successfully with:
- Taito K91X1204A J9100634A board. Works. Thanks, Murray, for the report.
- Taito K91X1204B J9100634A board. Testing included inputs on JAMMA edge, as well as Button 6–8 inputs on 14-pin JST NH header (labelled "B"). All work.
- Taito K91X1202A J9100633A board. Testing included inputs on 60-pin JST RA header (labelled "G1"). All work.
- Taito K91X1243A J9100633A board. Testing included inputs on 60-pin JST RA header (labelled "G1"). Button 5–8 inputs do not work; others do work.
- General issues:
- Depending on how your environment is configured, you might need to copy a compatible version of
iDmacDrv32.dlloriDmacDrv64.dllinto the same directory asfast2kb.exe. - If a COM2 port is present on your system, ensure that it is either unused or connected to a JVS board. If
fast2b.exeis able to open COM2, it assumes that COM2 is connected to a JVS board.
- Depending on how your environment is configured, you might need to copy a compatible version of
- MAME issues:
- Depending on the MAME version, you might need to tell MAME to use DirectInput as its keyboard provider. For example, in Command Prompt, launch MAME by running
mame -keyboardprovider dinput. Thanks, Ruben Gomez, for the report.
- Depending on the MAME version, you might need to tell MAME to use DirectInput as its keyboard provider. For example, in Command Prompt, launch MAME by running
The project has different build configurations for different keymaps:
- MAME: This configuration works well with the default keyboard controls in MAME (an arcade machine emulator).
- PPSSPP: This configuration works well with the default keyboard controls in PPSSPP (a PSP emulator). Because the PSP has many inputs and just one player, the keymap combines Fast I/O's Player 1 and 2 inputs to support just one PSP player.
- eX-BOARD and Deathsmiles II: This configuration works well with the keyboard controls in games for the eX-BOARD arcade system. Also, it works well with the keyboard controls in Deathsmiles II (the only game for the CAVE PC arcade system).
The following tables show the keymaps from Fast I/O inputs to keyboard inputs and from keyboard inputs to emulated controls in MAME, PPSSPP, eX-BOARD games, or Deathsmiles II.

- Test compatibility with other Fast I/O microcontroller boards, including:
- Taito K91X1234A J9100633A board
- Taito K91X1252A J9100633A board
- Consider adding fallback to JVS in case where Fast I/O is unavailable
- Increased polling interval to 2ms (for all configurations) to filter out unwanted inputs caused by mechanical switch bounce. Thanks, Murray, for the issue report and patch.
- Added error messages and graceful exit for cases where DLLs are missing or incompatible
- Added support for command line flag ("/?" or "/h") to show build info
- Refactored and optimized model of button states
- Corrected log messages about Player 2&4 Button 5 release
- Optimized cases where none of button states have changed
- Added keymap and build configuration for eX-BOARD, as well as Deathsmiles II (one keymap and build configuration for both). Polling is attempted at submillisecond interval (nominally, 0ms) with 0.5ms precision.
- Added 64-bit project configurations that use 64-bit drivers
- Added support for submillisecond timings:
- MAME configuration: Try polling at submillisecond interval (nominally, 0ms) with 0.5ms precision
- PPSSPP configuration: Try polling at 1ms interval with 0.5ms precision. (PPSSPP's menu screens cannot handle input at submillisecond interval.)
- Fixed undesirable power-cycling behaviour on Taito Type X2 and similar systems, where a JVS board is connected to COM2. The fix entails periodically sending a JVS Reset message to COM2, to prevent timeout of the JVS board's watchdog timer. If
fastio2kb.execannot open COM2 (e.g. if the system has no COM2 port or if another process already has an open connection to COM2), thenfastio2kb.exeproceeds without COM2 communications. On the other hand, iffastio2kb.execan open COM2 but COM2 is connected to some device other than a JVS board, then the connected device could malfunction due to incompatible communications. - Clarified log messages about Fast I/O ports
- Refactored code
- Added support for the following inputs:
- Player 3 Start, Up, Down, Left, Right, Buttons 1–8
- Player 4 Start, Up, Down, Left, Right, Buttons 1–8
- Coins 3&4, Test 2, Tilt 2, Service 3&4
- Escape 2 sequence: Player 2 Start + Button 1 + Button 3
- Escape 3 sequence: Player 3 Start + Button 1 + Button 3
- Escape 4 sequence: Player 4 Start + Button 1 + Button 3
- Enhanced MAME keymap to support Players 3&4
- Added early return in case where no I/O connection is detected
- Configured project to better ensure support for Windows XP SP2
- Added request for precise timer resolution via Windows Multimedia API
- Refactored code
- Added support for connecting Player 1&2 microcontroller board to either Port 1 or 2 of DMAC board
- Added support for extended keyboard scan codes
- Fixed bugs in mapping of Player 2 Up, Down, Left, Right
- Fixed type correctness issues
- Added license based on zlib License, with permission from Corey Griffith (fatal-bundy)
- Forked from fatal-bundy/KB2FastIO
- Removed unused files
- Configured project to support Windows XP or later
- Configured project to use Warning Level 4 (instead of 3) for greater strictness at compile time
- Replaced keymap by adding separate build configurations for:
- MAME keymap
- PPSSPP keymap
- Refactored code
- Added control handler function for cleaner termination
- Shortened polling interval to 1ms (instead of 10ms)

- Added support for the following inputs:
- Player 1 Buttons 7&8
- Player 2 Start, Up, Down, Left, Right, Buttons 1–8
- Coins 1&2, Tilt, Service 2
