Hardware Multiplayer (game)

You need a jacdac cable, not an audio jack, there is a difference, but they look the same.

Ok, can you point me to a jacdac cable? Because I fail to find one online.

Also, I’m a bit confused, because:

Maybe the spec changed in the mean time? What’s the difference between a jacdac cable and a normal headphone cable?

The data that travels, the ends are the same, but not the inside.

No you don’t need a special cable. It’s just a standard audio cable.

Last I checked, multiplayer via jacdac was being rewritten and they said it would work interminttenly / not work at all.

Ok thanks. Now I found the docs: We are still working and changing the Jacdac specification. Do not build devices using Jacdac.

Discussion seems to be taking place here: https://github.com/microsoft/jacdac/discussions

We demonstrate the use of JACDAC with hardware to play Arcade games 2 years ago. We have now switched over to SD Wireless to control 2 Meowbits with $13 SD Wireless chips into Meowbits. This does work, while JACDAC may not as of this time (April , 2021) : Our YouTube channel: MakeCode and Hardware demonstrates SD W system. Here is 2 year old JACDAC video: https://www.youtube.com/watch?v=YKshfoeGtbM

Great news, thanks! So you connect the 2 Meowbits to your WLAN network? How does pairing and communication protocol work in that case?

@Moobot , well, I don’t think it is with a WLAN network; there is no pairing. This is with 2 identical Arcade devices: Meowbit to Meowbit which have the SD Wireless slot on the top of the hardware console. This is not meant for an SD Card for data/game storage; NO. I have seen several sellers claim it is for storage and that is not correct. The slot is for an SD Wireless chip which has a radio antenna built in and two LED lights, one green for ‘radio’ mode and one blue for Bluetooth mode. In radio we can send signals with proper code installed in both Meowbits from one to the other so I can move my sprite on your console TFT screen. These sync up automatically with matching ‘radio group’ numbers. We have several Youtube videos with this comm. method and Meowbits to Meowbits and also Meowbit to Microbit . Search : MakeCode and Hardware channel for vids and code in description.

Does this cable works only with pygamer/pybadge? Does it works with some more devices?
