Genesis / Mega Drive microSD Flash Cart - Everdrive-MD-Style (Genesis + Master System)

One cartridge, the whole Genesis library - plus Master System

This is a microSD flash cartridge for the Sega Genesis / Mega Drive: drop your games on the card, pick from an on-screen menu, and play them on real hardware. It runs the entire Genesis / Mega Drive library, and because the Genesis has Sega’s 8-bit hardware baked in, it plays Master System games too - the same trick the old Power Base Converter did, built right into the cart. It’s a budget-friendly alternative to a Krikzz Mega EverDrive that does the same core job for a fraction of the price, and it’s tested and working before it ships.

What it actually is

Under the label this is a clone of the Krikzz Mega EverDrive - “EDMD” literally stands for EverDrive-MD. It’s the pre-FPGA design (CPLD plus flash), not the $265 FPGA-based Mega EverDrive Pro, and the genuine Krikzz carts run from about $75 (X5) up to $265 (Pro). I’ll be straight with you: it runs clone firmware, not a licensed copy - which is why it’s cheap, and exactly why I test every single one myself instead of trusting the factory.

That button on top - it’s a pause button, with a great backstory

See the button on the top edge, next to the SD slot? Here’s what it actually does, because it’s a genuinely neat piece of Sega archaeology:

• For 8-bit Master System games, it’s the PAUSE button. On the original Master System, Pause wasn’t on the controller - it lived on the console, wired straight to a hardware interrupt. The Genesis has no equivalent, and on real hardware the controller’s START button can’t stand in for it (that only works in emulators). So Sega’s Power Base Converter had its own pause button - and this cart bakes that same button right in. Without it, you literally couldn’t pause a Master System game on a Genesis.
• For 16-bit Genesis games, it’s a reset / jump-to-menu. Tap it to soft-reset or bounce back to the SD game-selection menu without power-cycling - especially handy on a Nomad, where the console reset is awkward to reach.

This is NOT a genuine Krikzz - and here’s why that matters (two genuine tiers)

Krikzz designed the EverDrive-MD this copies, and the genuine carts are worth knowing about - and here I’ll be extra straight with you, because on the Genesis the entry-level genuine option is close to my price:

• Closest equivalent: the genuine Mega EverDrive X5 (about $75) - the same non-FPGA class as this clone, done right, with official firmware and support. It’s only about $25 more than mine, so if you want genuine, the X5 is an easy call.
• Top of the line: the genuine Mega EverDrive Pro (about $265, FPGA-based) - a different animal entirely.

What the Pro does that neither this clone nor the X5 can:

• Sega CD games straight from the SD card (no add-on hardware needed), plus MSU-MD enhanced CD audio.
• Virtua Racing and other SVP games - reimplemented in its FPGA.
• Rock-solid special-mapper and EEPROM-save support, and official Krikzz firmware updates.

So why buy mine? Same as always: I test every unit, so you get a working clone without the gamble, at the bottom of the price ladder. But I’ll say it plainly - on Genesis the genuine X5 is only ~$25 more, so if official firmware and support matter to you, buy the real X5 and enjoy it. This cart is for folks who want the tested-clone tier at the lowest price. (Buy either one direct from krikzz.com if you’d rather support the creator straight-up.)

Compatibility, honestly

For the stuff you actually care about it’s great: the standard Genesis / Mega Drive library plays top to bottom, and the Master System catalog runs too. But a clone is not the equal of a genuine EverDrive, and I’d rather tell you than have you find out:

• Virtua Racing won’t run. It relies on the special SVP chip that only the FPGA-based EverDrives reimplement - no CPLD/flash cart (this one included) can do it. That’s specific to this hardware class, not “all flash carts.”
• Special mappers and EEPROM-save games are the soft spots. Super Street Fighter II’s oddball mapper and the EEPROM-save titles (NBA Jam, some EA sports carts, Wonder Boy in Monster World) are where a clone on frozen firmware gets flaky.
• No Sega CD and no 32X. Those need the actual add-on hardware - no flash cart of any kind replaces them.
• No official firmware updates. Krikzz’s updates are for genuine carts and can brick a clone - people have done exactly that. What’s on it is what you get.
• Region is unlocked, timing isn’t. It ignores region lockout, but it can’t convert a game’s 50/60 Hz video timing - a PAL-timed game still wants a matching console.

Everything else - the overwhelming majority of the Genesis and Master System libraries, plus the entire homebrew and ROM-hack scene - just works.

More than the classics: homebrew, backups, translations

An SD flash cart opens the whole modern Genesis world on real hardware, and like the NES there’s no such thing as a legal every-game multicart - every “Genesis 1000-in-1” is a pile of pirated ROMs. A flash cart is the honest version: neutral hardware, and you supply the games the legal way.

• Homebrew - the Mega Drive has a thriving modern homebrew and demoscene, with new games and huge ROM-hacks (some 10 MB+) that only run on real hardware via a flash cart.
• Fan translations - play Japan-only Mega Drive games patched into English on an actual console.
• Personal backups - dump the carts you already own for personal, no-distribution backup use. And honestly, making a personal backup of a game you own isn’t as hard as it’s made to sound - a $200 dumper is the fancy way, not the only way, and regular people do this at the kitchen table every day. I’ll leave the exact how to you, but if you’re curious, message me and I’m happy to point you at the beginner-friendly path.

Different shell, same board inside - all tested by me

Honest sourcing story, same as my other flash carts: I buy these validated by testing, not by brand. They show up in whatever translucent shell color the factory felt like using that week - the one pictured is blue, yours might be a different color - but the board inside is the same, and every unit I ship has been powered on and tested working by me. Because I validate each one on my own bench, I can buy the cheapest ones on the market and pass along only the ones that actually work. You get a tested cart; I eat the duds.

Load your own, or bundle it

Already play games on an emulator? Then you already have everything you need. A flash cart uses the exact same standard ROM files as an emulator like RetroArch - so if you’ve ever loaded a game on a phone, PC, or handheld, the files and the process are the same here. The only difference is you’re playing on the real Genesis and a real controller instead of a screen. No new software, no special format - drop your files on the microSD and go.

Ships with a microSD card, blanked and ready for you to load. New to flash carts? Message me and I’ll walk you through formatting the card, working the menu, and getting your homebrew or backups running. Setting up a whole Genesis? This is the “and the entire library” piece - pair it with a restored console and a real cart like Aladdin and you’re set. Got a Sega handheld too? There’s a matching Game Gear flash cart that does the same job over there.
