I’m punching myself for not buying an 8Bitdo M30 sooner, as it’s a near-perfect wireless Sega Mega Drive controller

For whatever reason, I’ve been unintentionally avoiding the 8Bitdo M30. That’s an absurd confession considering I’ve consistently cohabited with an original Sega Mega Drive for over 30 years, so you’d think I’d have picked up the wireless six-button controller at some point. Perhaps it’s the boxes of wired gamepads within my collection that pushed the accessory to the back of my mind, or the fact I already had a cordless set of buttons for special, wire-free occasions. I could spend all day making up excuses, but reality is that I’ve been missing out on a near-perfect wireless pad for the 16-bit system.

The specific version I’ve been tirelessly testing with Sega’s best retro console contender is the 8Bitdo M30 2.4GHz. Unlike its Bluetooth sibling, this gamepad is designed to hook up to an original Genesis/Mega Drive using a wireless receiver. Shove the dongle into the ‘90s machine’s old DE-9 controller port, hit the pair buttons, and just like magic, you’ve furnished your thumbs with a six-button pad that feels remarkably authentic given its unofficial status.

After five gruelling days using the 8Bitdo M30 with my OG console and the same Sega classics I’ve been playing for decades, I can confirm the M30 deserves the Mega Drive/Genesis retro controller crown. That regal status applies specifically to the 2.4GHz version, largely thanks to the included dongle in the box, but if you’re not fussed about absolute minimal latency, I’ll get onto why 8Bitdo’s Bluetooth solutions could be a more versatile fit.

A homage to a Sega gamepad you probably missed

As far as retro controller remakes and tasteful tributes go, 8Bitdo are masters at their craft. They both know how to make a gamepad that looks identical to an original and put a contemporary spin on a classic accessory. The M30 absolutely belongs in the latter category since it’s not trying to outright look like Sega’s six-button pad, and it actually draws inspiration from a Japanese version that didn’t make it to the US.

That’s not to say the West didn’t get a similar pad, but unlike the versions released in the US and UK, the Sega Mega Drive Fighting Pad 6B (also known as the JB-6000) is a smaller model of the six-button boomerang with a blue start button to match the Asian system. Side by side, it’s clear that the M30 was going for the same vibe rather than aiming for the dimensions of the Genesis and PAL region accessory, and in my humble opinion, it’s the superior design to pay homage to.

There are millimetres of a difference in width between the M30 and Sega 6B, so you’re practically getting the same size of pad. The good news is that, if you have large mits, 8Bitdo’s choice of dogbone design adds more surface area for your palms to rest on at the bottom and broader shoulders for your index digits to rest. The result is a take on ergonomics that still feels nice in the hands after several hours repeatedly playing Sonic the Hedgehog 2 or using all six inputs for serious Street Fighter 2 sessions. I’m sure there will be naysayers out there who aren’t into the smaller X, Y, and Z inputs or their dome shape, or even the very authentic feeling disc d-pad, but it’s certainly my go-to format for throwing punches.

Again, we’re talking about a modern spin on Sega’s pad rather than a direct remake, not unlike 8Bitdo’s N64 Controller designed to match the Analogue 3D. If you’d prefer the latter, you’ll want to look to Retro-Bit’s licensed six-button controller, as the UK version specifically looks like the PAL version without the cord. That’s the very pad I used for years when the need for no wires ever arose, and while it feels like the real deal, elements like micro USB charging are a bit of a bummer. The US version is also drastically different, squeezing extra inputs onto the OG larger Genesis design instead, meaning it’s not particularly authentic-feeling.

The licensed remake does feel almost exactly like the real thing, and even just having the Sega logo on the front helps facilitate the right vibe. That’s not to say that translates to excellent build quality, though, as it produces a pretty similar rattle to the actual six-button Mega Drive pad, which some people will find off-putting. By comparison, the M30 feels solid, swaps out the shiny plastic for a textured matte finish, and provides a reassuring sense of heft despite weighing just 114 grams.

Where 8Bitdo does commit controller sins is with its branding on the front. The gamepad maker has sort of moved on from slapping its full text logo on pads, but the long-form title is present on the M30. To add insult to injury, the printing on my specific pad appears to be squinty, and while that initially deeply upset my neurospicy brain, I later realised that the Sega logo on my real six-button Japanese pad is also slightly slanted. Go figure.

Unlike its Retro-Bit rival, the M30 includes modern perks like convenient USB-C charging, all while providing an extra turbo toggle alongside additional shoulder, home, and select buttons. The latter three are really geared towards PC and Switch use, something you can do wirelessly with the Bluetooth version, but the 2.4GHz also supports wired play.

Kill the cord, not the hedgehog

I’ve already spoiled the fact that playing Sonic The Hedgehog 2 is my Mega Drive and Genesis controller litmus test. I’m using plenty of other 16-bit Sega classics to put the M30 through its paces, don’t worry about that, but the mammal formerly known as Mr. Needlemouse and his sequel are my first port of call when testing refurbished gamepads or reviewing newcomers.

The need for responsive controls isn’t remotely exclusive to Sonic 2, but the sidescroller will punish you for making the wrong moves at an unfortunate time. All it takes is one misstep walking onto Chemical Plant Zone’s irritating moving platforms, and you’ll sink to the bottom of the drink, and don’t get me started on this damn Metropolis Zone starfish. Cutting the cord by using the M30 could make moments like those all the more painful since wireless signals will introduce latency. The fantastic news is that, thanks to its 2.4GHz abilities, 8Bitdo’s pad keeps lag to an absolutely unnoticeable minimum, and I don’t think I’d pass a wired vs wireless Pepsi challenge this time around.

If anything, I found that since the M30 is box-fresh, its buttons felt more responsive than my original Japanese pad. That’s despite having refurbished it myself, but there’s only so much you can do for original aging membranes. Not once during my most recent Sonic 2 playthrough did I feel like the gamepad was impeding my ability to blast through to the Death Egg, and I actually felt like I sucked less at the infuriating pseudo 3D special stages.

Sonic aside, the pad also impressed across every Mega Drive/Genesis genre I could throw at it. Again, while playing everything from punishing shmups like Truxton to six-button romps like Street Fighter 2 and Comix Zone to the chaotic run-and-gun Treasure classic Gunstar Heroes and the wonderfully janky Golden Axe, not once did I encounter input issues. It could be a gamepad placebo effect, but I genuinely felt like I was on my A-game throughout my weekend-long Sega marathon, and that might simply be due to the M30’s design and feel.

I’ve been continually playing the same segments of games while swapping between various wired pads, the Retro-Bit 2.4GHz controller, the M30, and even a Bluetooth Retro Receiver paired to the Gulikit Elves 2 Pro. Out of the three, 8Bitdo’s contender wins out in terms of ergonomic feel, largely because it blends the size of the JB-6000 with the texturized finish of the OG three-button accessory, but in truth, all three feel true to Sega’s ‘90s approach to controllers.

The feel of a controller in your hands is arguably just as important as responsiveness. For instance, the less textured finish on a d-pad can affect thumb grip, and when testing the Retro-Bit Sega Saturn Pro controller and the Mega Drive version, I found that it made things feel too slidey during twitchy moments. At the same time, while all three have great directional feel, the Elves 2 Pro features a slightly nicer pivot, albeit with a conventional button layout since it caters to multiplatforms.

Is using 2.4GHz vs Bluetooth a biggie?

The question that lived in my head rent-free while testing the M30 is whether opting for the 2.4Ghz over its Bluetooth counterpart actually matters. It’s cheaper if you’re sticking to just Sega’s console, yet, but it means you can’t just buy the one controller and sync it up to various systems using 8Bitdo Retro Receivers.

The fearmongering element here is that Bluetooth commits the retro console cardinal sin of introducing more input latency. Lag is something that terrorizes classic setups already, since using modern displays and upscalers typically introduces some delay in terms of visuals, so the wrong gamepad could make things feel even more out of whack. This admittedly matters more in games that require super reactive and responsive moves, which naturally applies to most ‘80s and ‘90s systems with arcade levels of difficulty.

Technically, 2.4GHz features lower input lag than Bluetooth, and the difference can look like a gulf. The issue is that I haven’t really felt any real delay when testing pads like 8Bitdo’s N64 or even the Elves 2 Pro with various Retro Receivers, so I decided to embark on a side quest to see just how much lag there actually is. There are very complicated ways you can measure this, including using expensive oscilloscopes to literally visualize frequencies, but I’m opting instead to use high frame rate slow-mo video.

I want to keep things simple, so to tie in with this M30 review specifically, I’m pitting it against the 8Bitdo Bluetooth receiver and the Elves 2 Pro. To get a baseline sense of any lag, I’m using the Life Meter dial in Golden Axe to see how quickly d-pad presses kick in. Even before working out lag based on a 480Hz clip, it was extremely clear that the 2.4GHz was pinging the button press near instantaneously, and it turns out only takes 4ms on average to register.

That’s actually bang in the middle of the 1-6ms range expected from 2.4GHz, so I’m pleased to see the latency ring true. It’s what I’d firmly deem as undetectable lag, even though my wired controller registers the same d-pad press in less than a millisecond. While I’m planning to explore whether all 2.4Ghz controllers are equal in the future, I also tested the Retro-bit Mega Drive pad in the same fashion, and around 6ms on average, which is the same ballpark as the M30

The big question here is whether Bluetooth features the expected increase in lag, and when it comes to the Elves 2 Pro connected to an 8Bitdo Bluetooth Receiver, the answer yes. The same tests using the Retro Receiver measured in at around 18ms, but that’s actually pretty on the nose for when it comes to the wireless tech. There are plenty of factors that will affect performance, like jitter and signal interference, and I’d be lying if I said I could feel the latency throughout my qualitative testing.

I don’t have a Bluetooth M30 to hand (yet), so I can’t confirm right now whether it’ll provide the same level of latency as the Elves 2 Pro. You’d hope 8Bitdo’s own pad and Retro Receiver somehow provide better performance, but these tests at least provide an idea of what to expect from the other model. If you’d prefer something you can easily use with multiple consoles, I wouldn’t let the lure of lower lag with the 2.4Ghz draw you in, even though it’s technically the “best” option for Mega Drive/Genesis specifically.

Battery life boons

Naturally, I’ve been keeping tabs on the M30’s battery life, and, well, I haven’t charged it since freeing it from its box six days ago. For the record, I’ve been diving into my cartridge collection every evening for around 5 hours, so it’s already living up the 35 hours of runtime 8Bitdo claims its 480mAh battery can deliver.

Of course, if you opt for the less efficient Bluetooth version, that runtime figure falls to 18 hours, which is still fairly decent. That is another reason to specifically buy the 2.4GHz M30, though, especially if it’s larger for your Mega Drive/Genesis setup. Charging is speedy too at 1-2 hours via USB-C, but the fact that there’s no way to recharge straight from the console is always irritating. Sega’s controller port simply isn’t capable of supplying the right juice to newfangled controllers to supply a charge, whereas later systems like the Dreamcast can actually do that (watch this space for my Retro Fighters Striker review).

A curious connection quirk

I’ve played a lot of Sega Mega Drive and Genesis games with the 8Bitdo M30 throughout the testing process, and I even snuck in some time with the Mega CD too. Throughout the process of jamming various carts into the system and assessing whether the 2.4GHz pad feels right, I stumbled across a weird hiccup that seems to impact any pad that uses a dongle.

The issue applies directly to the 1998 brawler Street Smart, and kicks in before you can even start fighting to “win money, girls, and glory on the streets.” For whatever reason, the game will only respond to a controller if it’s connected before powering on, and since 2.4GHz and Bluetooth dongles normally take a second to spring to life, the code that checks for a gamepad blocks it from working.

I’m unsure how many other Mega Drive / Genesis games are affected by this, as Street Smart is the only one I have within my collection like this. The workaround is to plug in a wired controller, then swap it out with the wireless receiver once the start screen appears, but that could leave players who only have the one 2.4Ghz or Bluetooth pad in a pickle. I suspect there are very few outings that the quirk actually impacts, but I’ll be on the lookout for more as they enter my collection.

Should you pick up the 8Bitdo M30 2.4Ghz?

The 8Bitdo M30 shouldn’t outright replace original wired gamepads, but the 2.4GHz version is the best wireless controller for your Sega Mega Drive / Genesis right now. Everything from its solid connectivity and fantastic battery life to the fact that it feels just as nice in the hands as an officially licensed accessory easily wins this accessory the crown, and cutting the cord for 16-bit classics seems to come with minimal caveats. By extension, the Bluetooth version is also worth a look, too, especially if you’re looking to play on Switch or use Retro Receivers with other compatible consoles, but that strategy will ultimately cost you more and come with battery and latency compromises.

That said, there is one thing missing from the M30 package that would have earned it a perfect score, and that’s an extra USB 2.4GHz adapter. Yes, such a thing does exist, but the version is sold separately and swaps out the 9-pin joystick dongle for something with Mega Drive Mini and Switch support. This is something Retro-bit gets right since most of its 2.4GHz pads include both, and I reckon 8Bitdo needs to up its game in this department across its entire range.

Still, the M30 is still a standout Sega controller, and the Mega Drive / Genesis version is the one you should grab for wireless play. I’ll be looking into trying out the Bluetooth version when I have the funds, which could pose a threat to Retro-Bit’s current best Sega Saturn pad status since 8Bitdo even has a colorway to match the Japanese system.
