[Review] 8BitDo M30 – Wireless control for Mega Drive – AliExpress

The 8BitDo M30 is a Wireless Controller for Mega Drive (Sega Genesis). It was acquired on AliExpress, in the 8BitDo official store (8Bitdo Official Store), for use with my Analogue Mega Sg, which I will talk soon here in Skooter Blog. I can also use it with my Sega Genesis, my Mega Drive III, my Master System II, and even PC, USB Cable, or wireless with the use of a adapter.

Motivation and Purchase

The 8BitDo M30 It was announced along with the Analogue Mega Sg. Nevertheless it does not follow the console, that can be used with any compatible control with the original Mega Drive. Likewise, the 8BitDo M30 It is not for the exclusive use of Analogue Mega Sg, and it can be used with any Mega Drive.

But there is a clear advantage in using the 8BitDo M30 to Analogue Mega Sg. He brings a button used to access the console menu, without using a key combination.

The 8BitDo M30 also it has a very attractive price. At the time of writing this article it is costing R $ 94,38, including free shipping by AliExpress Standard Shipping (ePacket), that has no postal order rate. For comparison, Tec Toy sells a control 6 buttons wired by R $ 99,90.

The 8BitDo M30 I was in pre-sales in US Amazon for $ 24,99 since shortly after his announcement, with delivery scheduled for the month of February. I got interested but held buying, because I was sure he could buy directly from Chinese pay a much lower shipping and no tax.

And that's exactly what happened. No give 27/02 the 8BitDo M30 apareceu na AliExpress, in the 8BitDo official store (8Bitdo Official Store), for the same $ 24,99, but with free shipping. A Bluetooth version and the receptor Bluetooth They are also on sale at the official store.

I'm interested in two 8BitDo M30 for my Analogue Mega Sg. I'm also interested in Bluetooth version for use with emulators. But I held the anxiety and just bought one to know if it's good even before you buy the other.


The shelf of the box 8BitDo M30 It came within another of cardboard and plastic bubble box wrapped in. Thus we arrived in great condition, no pecked or wrinkled. Note 10 for the packaging 8BitDo.

Inside the box we, in addition to the driver, or receiver, a USB cable, and the instruction manual.

The control has a good construction and is very comfortable in the hands. Buttons and D-pad also pleased me. I found nothing that displeased me 8BitDo M30 this first contact.

Check out the photos and the video of the unboxing from the 8BitDo M30:


The first thing I did with the 8BitDo M30 It was updating the firmware, since shortly after the release began to encounter problems when two complaints 8BitDo M30 They were used at the same time.

Shortly thereafter came the update firmware which corrected the problem (2.00), but by then my 8BitDo M30 I was already on the way, so naturally it came without the update.

The 8BitDo probably did not have the need to upgrade firmware from the 8BitDo M30. In the Bluetooth controllers it is natural that updates need to be made, because they connect directly with current consoles, like Nintendo Switch, that can be updated and breaking connectivity with controllers, requiring modifications in form of connection.

But in versions 2.4G, using closed protocol and connect directly only to its own receptor, I believe the 8BitDo not had that need updating firmware after launch. I say this because the USB port of the receiver is not exposed, and you need to open the case. Further complicating, the screws are of the type torx, less common than the slot philips. Luckily my kit of electronic tools that's almost 10 years realized the job.

Both the control of the update as the receiver are made differently than the other controls the 8BitDo. There is no software to update. The device only presents itself as a storage device, and then copy the file firmware into it. But everything went smoothly.

The 8BitDo M30 It came with battery power and still did not have to recharge it, despite having played for a few hours, then I believe that autonomy is large.

On two occasions I hung up and quickly religuei the Analogue Mega Sg, the 8BitDo M30 lost connection and it took a while to find, something I had already observed in SNES30.

I hope the battery life is long, for I have seen a picture of 8BitDo M30 Open (which unfortunately I am unable to find again) and there seems to be a common battery. Furthermore, the battery wires are soldered to the board. When this battery possibly goes down, You will need to find and weld a new. Many people find it silly to think, but I think a valid concern for a control of a console that already has more than 30 years since launch and continue playing, and we hope that we can still play other 30 or but. My wireless controllers with its nearly 30 years still work. The 8BitDo M30 work from now 30 years? Only time will tell…

And now let's test 8BitDo M30 and see how it behaves on each system. Check out.

Analogue Mega Sg

On Analogue Mega Sg, the shoulder buttons, L and R, clones are treated as buttons C and Z. The Star button is to enable / disable the turbo buttons. Just hold the button you want to activate the turbo and press the star. To disable the turbo procedure is the same.

The Home button 8BitDo M30 behind the Mega menu Sg, which can also be triggered with a key combination defined by the user. But the Home button is much more comfortable.

Mega Drive (Sega Genesis):

Us Mega Drive and Sega Genesis original, L and R buttons are also treated as Z and C. The Star button also serves to enable / disable turbo buttons, as in all Analogue Mega Sg. Only the Home button has no function in this case.

You can enable mode 3 buttons (holding the MODE 3 seconds) so that the 8BitDo M30 behave as a control 3 buttons. This mode is useful for control with incompatible games 6 buttons, like Golden Axe 2.

Unfortunately there is a Master System mode, for incompatible Master System games with Mega Drive controls, like Monica in Dragon Castle (Wonder Boy in Monster Land). These may not be played in a Mega Drive original with the 8BitDo M30. Note that this problem does not affect the Analogue Mega Sg.

Master System

On Master System the 8BitDo M30 It works like any control Mega Drive, with the buttons B and C taking over the functions of the buttons 1 and 2. As the R button clones the C button, it also acts as 2. The Star button activates and deactivates the turbo function. The other buttons have no function.

Some games, like Monica in Dragon Castle (Wonder Boy in Monster Land) They do not work because they are not compatible with Mega Drive controls.

Using the application SMS Genesis 6 Button Controller Test by Charles MacDonald (PD), all Mega Drive buttons (D-Pad, A, B, C, X, And, From, START, MODE) They are correctly identified.

Windows 10 USB cable connection

The 8BitDo M30 It can be used in Windows 10 connected using the USB cable. It should work in earlier versions of Windows also, but I have not tested.

No Windows 10, The buttons, B, C, X, And, From, Mode and START are treated as buttons 1 a 8. The D-Pad is treated as analog axes X and Y.

L and R are treated as a single analog axis Z, which is centered when any button is pressed or when both are pressed at the same time, and moving to one side as a button is pressed.

The Star button is used to activate / deactivate turbo buttons, and the Home button back to Windows game bar.

Windows 10 with an adapter for receiving controls and Mega

I have a Adapter cable to connect two joysticks Mega Drive (Sega Genesis) the PC via USB, that I showed here in Skooter Blog. With it gives to connect the receiver 8BitDo M30 and use it wirelessly on PC.

In this case, The buttons, B, C, X, And, From, Mode and START are treated as buttons 1 a 8. The D-Pad is treated as X and Y axes. L and R are treated as Z and C clones.

The Star button is used to activate / deactivate turbo buttons, and the Home button has no function.

8BitDo M30 versus Krikzz Joyzz

That's the big question, which one is better: the 8BitDo M30 ou o Joyzz of Krikzz?

I confess that I can not answer it. Both are great controls. Both are comfortable and allow you to play for a long time without tiring. What I can do is point out the advantages of each.

advantages of 8BitDo M30:

  • Home button to bring up the menu Analogue Mega Sg directly;
  • Turbo function can be activated individually for each button;
  • shoulder buttons;
  • USB out even;
  • lowest price;
  • The screen printing does not come out.

advantages of Joyzz of Krikzz:

  • Longer Battery Life;
  • Battery Nokia BL-4C;
  • format identical to the original;
  • mode 2 buttons for Master System games;
  • Application flashcarts that provides information on status of the controls;
  • always immediate synchronization.

Final Considerations

I was quite pleased with the 8BitDo M30 is a Wireless Controller for Mega Drive (Sega Genesis). É mais uma excelente opção de controlador sem fio para o Mega Drive, as well as Joyzz, mas custando menos da metade do preço.

Também é um casamento perfeito com o Analogue Mega Sg, incluindo o botão Home para acesso rápido ao menu. É o controle que tenho usado com o meu Analogue Mega Sg. Moreover, uma coincidência: Mega Sg and 8BitDo M30 vieram de cantos opostos do globo terrestre: EUA e China, mas chegaram em minhas mãos no mesmo dia.

Hello. Thank Skooter for quality content.

I was far away years of retro games and now plan to return, immediately I intend to buy a MEGA (national or Chinese), but I will wait for the launch of the Mini Mega to compare.

My question is about the new controls 8BitDo, Krikzz, new Tectoy (3 and 6 buttons), Controls Fei Hao and some parallels (as Capcom Street Figther – white), are all compatible with SG, new Mega, Fei Hao and Mega Old?

In addition there is a large difference in response time and gameplay, right now I'm not worried about being wireless or not, only seek to present a control delay does not confuse vertical or diagonal with.

If possible is to sort in scalar 0-5, these differences.

If you can help me I thank you very much, although it would give a great review this team kkkkk.

Thank you.

You can use Turbo chargers to charge this control? The known quick charge… Not to load faster, but because it is the only available. Does it damage the appliance?!
