Wireless joystick for Amiga/C64/Other:

Internal transmitters. Receiver, plugs into computers both joystick ports. External transmitter


2020-08-20: Prototype 2 of very tiny internal transmitter v2 (which is even tinier) is working.
2020-05-12: Finally figured out how to make RetroPie/Linux see it as two separeate joysticks. See bottom of page.
2019-07-07: Prototype of very tiny internal transmitter working.
2018-02-09: SW done!
2018-01-01: Pairing working! SW almost done.
2017-10-15: USB working well.
2017-02-05: USB functionality working in alpha SW.
2016-12-05: Prototypes done, working. SW needs improvement.

What is it?:

The system consists of a base board (receiver) and a number of transmitters (usually two), either internal for mounting internally in a joystick (is plug and play for Tac2) or an external transmitter for any joystick. The transmitters are powered by a CR2032 that will last for years(?).

The base board has two DB9F that connects to both joystick ports of an Amiga, C64 or other computer with the Atari style DB9F-joystick ports. It also has a micro-USB connector for windows/linux/mac/android. It will show up as two digital joysticks to use in an emulator! Plan is that the board should also be able to connect to a PC via micro-USB to be able to use the joysticks wireless against an emulator running on the PC.

Current features
Possible future features include autofire, one joystick to both ports and the ability to make an Amiga-mouse wireless in the future.

Make it show up as two separate joysticks in Linux/RetroPi

Start a terminal and write:

cd /boot
sudo nano cmdline.txt

This starts the nano editor editing the cmdline.txt file. It probably has one long row of text in it. At the end of that single raw, make a space and add the following text:


Save with CTRL and x. Reboot!

If you like to have a tool to test with i recommend: "jstest-gtk"
