MAYFLASH SEGA Genesis Mega Drive Controller Adapter for Switch NS/OLED Model & PC Windows SEGA Genesis SEGA MD Adapter MF104

Excellent condition. I use it for my Nintendo switch to play Sega games. But for some reason on Nintendo switch, the C button is mapped to L on a regular controller. Would prefer the Y,B,A Button trio, but overall a good adapter if you’re into retro gaming on newer consoles.

Very good product. I like it.

I have it in the correct mode, latest firmware, and using a selection of joysticks. The joysticks work to navigate the Switch main screens, but they don't actually work inside of any games. Most notably, Atari 50th anniversary doesn't work, which is the main game that you would want to work.

I had originally bought this to use with the Hyperkin Ranger. I have since found out from Mayflash that the MF104 does NOT support the Ranger. The Ranger works flawlessly with a vintage Atari 800XL though, so not a total deal breaker.I had issues updating the MF104 to the new firmware to support Atari 2600 controllers. Totally expecting to completely be ignored or if any response to just get a "copy/paste" from the online manual. To my surprise, Mayflash support responded over night. They had sent a link to update the MF104 with the MF103 firmware. I thought this was an error, but it did lead me back to their site to see there was a link for a MF104, V1.00.22.08. I downloaded that and it just failed over and over. I wrote back, and again they responded right away. They said the firmware for the MF103 & MF104 are the SAME. So I downloaded the firmware from their site for the MF103 and it flashed the MF104. It worked perfectly as expected.I do not have a switch, I am using this on a PC to use my vintage Atari controllers with an Atari 800 Emulator. It is now working as expected so I am very happy. I am also VERY impressed with the support provided by Mayflash.Also, it may seem confusing... Mayflash lists the Atari 2600 firmware update for the MF104 as v1.08.13 dated 12-29-2020. When you flash the MF104 with that firmware, it will actually appear as firmware V1.00.08.13. It appears they left the "00" after the "1" off on the website listing.As of today, 6/17/2023... there is a firmware for the MF103, V1.00.22.08. That is the firmware that worked for me. For some reason the firmware download of the same version, V1.00.22.08, for the MF104 did NOT complete for me. It was the MF103 linked version that worked and the vintage Atari 2600 controllers now work using Xinput in the emulator. I setup custom mapping for them in the Atari 800 emulators.I was hoping the Ranger would work, the vintage Atari controllers work but anyone who has used them knows they feel horrible! Since this unit supports the Sega controllers, might see if I can find any that don't feel horrible.

Worked perfectly out of the box for connecting a Sega Genesis controller to Nintendo Switch. After updating the firmware through manufacturer’s website, Atari 2600 controller worked on the Switch as well. Great item for playing retro games on the Switch!

Funciona muy bien con los controles de sega.

Before this product (model MF104), Mayflash used to sell a small rectangular Genesis->USB adapter with the name "MEGADRIVE Controller Adapter for PC USB" (it has no obvious model number that I can find).I had 2 of those old model adapters. The older version was DirectInput only, but the later version had a physical switch on it to select between DirectInput and XInput mode. That later version was perfect. Everything worked, no driver or firmware intervention needed, and that switch allowed you to easily select whichever mode was needed.But I lost it.Eventually I gave up on ever finding it, and bought this new model to take it's place. It was a disappointment. The good news is that in the midst of my frustration a beam of light entered my brain and I remembered where to find the old one. After comparing the old and new models, I've decided to send the new one back. If the new model had worked properly I would have kept it, but it has serious problems (or at least my example does).Problems with this model============================Firstly - it's a bit bulkier than the old design. It also has Turbo and Autofire features that I think are superfluous and will only create possible headaches if they get accidentally enabled, but maybe there's some people out there who actually want that feature. Personally I think the only time I'd want Turbo is in a few old NES games, and emulators will offer that function themselves in software. Autofire? Even less useful.In addition to DirectInput and XInput mode, this new model now has a 3rd mode of operation to work with Nintendo Switch. That may be useful to someone who owns a Switch, and could be a good reason to prefer this model in that case.My complaint is the way you switch modes. The old model had a simple mechanical switch on it with labelled positions. It was easy to tell what mode it was in by just looking at the switch, and to change modes by just moving it. On this new model the switch is electronic - you have to hold the "HOME" button for 8 seconds to change modes, and remember what each color of LED represents (it's not labelled on the device). Probably not a big deal as long as you don't forget how it works or what the colors mean, but a simple mechanical switch is simpler IMO. Why is it called the "HOME" button? I have no idea.OS compatibility:I'm not a Linux guru, but I couldn't get this device recognized under Linux Mint 19.2 when in XInput mode. It's recognized in DirectInput but not XInput. Not sure why that's happening because the old model works readily in both modes - I just plugged it in and confirmed this. Same system, just plugging in the different adapters to the same USB port - the new model won't detect in XInput mode but the old one works readily in either mode. It's hard not to blame the device with such a simple A-B comparison as that.Under Windows 7, XInput mode does work with the new model, so it's not necessarily broken, just not as compatible.Under Windows XP, this unit did not work at all. It seems to want a driver. I wouldn't count on finding an XP driver for something this new, but maybe something generic would work. The old model works in XP without any driver installation required.Sega "MODE" button problem:Regardless of whether I use this adapter in XInput(green LED), DInput(blue LED), or Switch(red LED) modes, the "MODE" button on Sega 6-button controllers will not work. This *is* a detectable button on Sega controllers and is supported by the old model.Supposedly this issue can be fixed by updating the firmware. That did not fix it for me.The flash software, found at Mayflash's web site, contains the word "SNES" in the filename which is a confusing error on their part - but triple checking will confirm you did download the correct file. It requires Windows to run. It appears to work on WinXP but I didn't figure out how to use the utility correctly until I had rebooted to Win7.The software doesn't explain a non-obvious step you need to take to make it actually detect and flash the device. This information is listed in the readme file. Anyway, I did update the firmware to version 1.08.13 which explicitly claims to fix the problem with the Sega MODE button. The firmware utility ran a checksum and reported success when finished. Yet the problem remains the same. The button is still not detected in any mode (all other buttons work).Presuming that my unit is defective, let's go on to how it's *supposed* to work. One of Mayflash's web pages says that even after the firmware update, the Sega MODE button will only be supported in DirectInput mode, not XInput mode. Another reviewer here has reported the opposite - that XInput supports it but DirectInput does not. Either way, it's potentially a big problem depending on what mode is required by the games you want to play. Mayflash's old model Genesis->USB adapter doesn't have this issue - all buttons work in both DInput and XInput - I just now tested that so I'm certain. So this limitation is a regression compared to the old model.After I found where I had misplaced my old model Mayflash adapter, I plugged it in and found it to do everything perfectly on the first try which had frustrated me with this newer model, so I'll be returning this new one back to Amazon. I just wish the old model was still available for sale. The old Amazon page where I bought it years ago just shows the item as permanently out of stock. I couldn't even find them on eBay. If Mayflash brought back that version, I'd buy another.

Worked right out of box
