Hi,

I just received the new 8BitDo M30 for original Mega Drive and works with the JoyMega on the Zemmix Neo but I have micro disconnections (lost one or two keystrokes every few seconds).

I don't know if is a power problem of the RS232 (the M30 transmitter is powered by the RS323 only) or the JoyMega.
Anyone else is experience the same behaviour?

Thanks,
Dan

I can’t say yet, but I just ordered the 8BitDo M30 Bluetooth controller and MegaDrive Retro Receiver, so let’s see :).

It's a well made controller.

Maybe are interferences from the Zemmix Neo.
I just bought a serial extension cable to check it.
If it's a power problem the cable should make it worse.

I'll keep you updated when I received the cable.

Thanks,
Dan

@Daba

Is your JoyMega made with a transistor, or does it have a chip? JoyMegas made with transistors are known to be problematic.

About the extension chord: a serial extension cable might not have all the wires inside. There are real controller extension cables specific for Sega Genesis/MSX/etc available on eBay.

Thanks @sd_snatcher

Is the transistor model. That's could be the problem. oO
I can't find where I can buy one with chip.

About the cable I bought is this one: 2m Serial EXTENSION Cable Lead 9pin DB9 M - F RS232 6ft
I choose this one because says:
Connection Split/Duplication: None (1 : 1)

If it doesn't works, I'll buy the one you recommends.

Thanks much.
Dan

Well, finally I found the problem.

After do several tests and check it with the JoyMega with chip version (Thanks much @roadfighter) I found the problem.
The first version of the firmware has an issue and can be solved updating the receiver and the gamepad.

Fimware v2.00
1.Fixed the connectivity issue.
2.Fixed the latency problem.

Here more information:

And if someone is interested, here they are testing the lag:

Thanks for notifying.
I also acquired an M30 2.4g gamepad: Out of the box it has the old firmware.
I had to update the firmware on both the dongle and M30 2.4g gamepad to firmware v2.00.

And did you get a chance to test the Megadrive Retro receiver ? I was wondering how i works so far.
Also the possibility to connect other Bluetooth controllers looks promising.

I posted my experience here:

I got my 8Bitdo M30 controller + MegaDrive Retro bluetooth receiver yesterday. Just tried it, works like a charm on my turboR via JoyMega! It also supports other wireless controllers like PS3 / PS4 controllers, so you don’t necessarily need to buy the M30, although I haven’t tried it yet.

It feels very light and is closed by two tiny Allen key screws, too tiny for the smallest key I have, but it seems easy to open without damage once you got the right size. I wonder if there’s some room for a JoyMega modification inside.

Having a wireless controller’s nice, I should find some room under my TV now :).

Yeah and the receiver is pretty cheap, just 20 bucks.
