The Sega Genesis (Mega Drive) still rocks in 2025—crunchy FM sound, lightning-fast platformers, and a library that’s aged way better than anyone expected. If you’ve dragged a Genesis out of the closet (or scored one locally), you only need a few smart accessories to make it sing on a modern TV. This guide covers controllers, HDMI solutions, power supplies, and storage that just work—no soldering iron required.

Controllers: wired accuracy vs. wireless comfort
Retro-Bit Official 6-Button (wired)
The 6-button layout is practically required for fighters and shines in shooters and platformers. Retro-Bit’s officially licensed pads nail the D-pad feel.

Arcade adapter options
If you want arcade-stick vibes, look for USB adapters that let you run a modern fight stick through a Genesis-compatible converter (results vary—check reviews for lag).
Video: getting a clean HDMI signal
Console-specific HDMI cable (easiest)
These cables plug into the Genesis AV-out and convert to HDMI inside the cable. Picture is cleaner than generic AV2HDMI boxes and set-up takes seconds.
AV2HDMI (budget)
Use if you just need a picture fast. Quality varies; enable Game Mode on your TV for less lag.
RetroTINK (best overall)
If you want the best image with minimal fuss, a RetroTINK upscaler handles 240p/480i beautifully and feeds your TV a clean, low-latency signal.
Power: safe replacements and multi-console bricks
Old wall-warts drift out of spec. A modern, regulated PSU helps protect your hardware. If you run multiple consoles, consider a multi-output power brick with correct voltage/center polarity for each system.

Storage & cartridges: play your library the easy way
A high-quality flashcart (e.g., EverDrive MD) lets you load legally owned backups from an SD card—perfect for preserving fragile originals and trying translations/homebrew.
Note: Only use backups you legally own. Keep your carts safe; use the flashcart as your daily driver.
Cleaning & maintenance: cheap fixes that matter
Contact cleaner and a basic retro cleaning kit solve most video dropouts and controller weirdness. Don’t sleep on this—it prevents hours of head-scratching.
