Pin spacing is 2.54mm. For example this works: https://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/5530841-5/5530841-5-ND/2259225

Development cartridges from V.Tech used flash memory: SST 39VF6401B

Production cartridges use a “blob” and it's unknown what exactly is under it. Probably mask ROM.

Controller port

6 pin mini DIN (like PS/2 keyboards and mouse). It is a serial port at 4800 baud, 8N1.

Pinout (using the standard numbering for mini-DIN connectors) :

  1. VCC
  2. CTS (from V.Smile)
  3. Tx (from V.Smile)
  4. GND
  5. Rx (from controller)
  6. RTS (from controller)

Flow control

When the console sends a byte, first CTS goes high, then the console sends the bits on the Tx line. When done, CTS goes low again.

When the controller sends a byte, RTS goes low first, then it waits for CTS to be up. Then RTS goes up and sends its byte. Finally CTS goes low again.

If there are multiple bytes to send, RTS remains down until the start of the last byte.

Messages from the controller

When idle (no buttons touched), the console sends a byte every 20ms, it seems to be partially random. I've seen E6, D6, or 96.

Every second the controller sends 55 if nothing else is happening.

Common to joystick, dance mat and keyboard
Button Press Release
OK A1 A0
Quit A2 A0
Help A3 A0
ABC A4 A0
Idle (nothing) 55

Joystick

The joystick has 5 levels of precision in each direction. For example, C3 is “slightly up”, C7 is “all the way up”.

The 4 color buttons are allocated one bit each in the 9x range so it's possible to manage multiple of them being pressed at once.

The other buttons are Ax with x just being the button number, so it's not possible to handle multiple of them being pressed at the same time.

Joystick
Button Press Release
Green 91 90
Blue 92 90
Yellow 94 90
Red 98 90
Up C0 83 to C0 87 C0 80
Down C0 8B to C0 8F C0 80
Left CB 80 to CF 80 C0 80
Right C3 80 to C7 80 C0 80

Dance mat

Every press sends at least a “joystick position” 2-byte pair, and possibly an extra byte for the button itself (some buttons report as joystick moves, other as separate buttons). The mapping is not at all compatible with the joystick and seems a bit random. Note that for example 8B and 8D are different buttons, where on the joystick it would be different positions in the same direction.

  • Escape is mapped to Quit and works the same
  • Help is mapped to Help and works the same
  • Enter is mapped to OK and works the same
  • Shift sends A9 on press and AA on release
  • Other keys send their code on press, and code | C0 on release (so no code will be in the 90-AF range for either press or release to not conflict with the special buttons)

The joystick at the bottom of the keyboard is similar to the normal Joystick but uses different values (to avoid clashing with the keyboard release keycode range). There does not seem to be different values possible, it's all on or all off.

  • Left: 7F 80
  • Right: 77 80
  • Down: 70 8F
  • Up: 70 87

Commands from the console

61, 62, 64 and 68 are sent in reply to color buttons presses. I suspect this controls the lights in the buttons. 60 is sent to turn the light off.

These are repeated every 20ms. After the controller sends 55 (idle), the V.Smile also returns to its idle reply (E6 for example) every 20ms.
