A brand new, smaller alternative to the original Power Base Converter. Comes in BitBox case with insert.

  • Translucent Red shell***
  • Works in some clones, including the RetroN5 and Retro Freak*

† Nomad and Genesis 3 requires modification to work with Master System games. (Google: Nomad Master System Mod)

** Does NOT support Master System card games or any accessory that requires the card slot.

 ***If you need a shell with a side-notch for a Japanese console please email us at [email protected] with that request.

    Perfect size for Sega Nomad!

    Posted by Jean Paul Oyhenart on Sep 15th 2021

    I have the original powerbase converter for the genesis. But I needed something more compact to take on the go. The original powerbase converter doesnt work with the nomad but this one does. Its phenomenal! Works perfect with no issues whatsoever. For those of you who don't know the Nomad isn't backwards compatible even with the powerbase. You still need to mod it internally. But the powerbase mini fits perfect. I use it on my genesis ii and on my nomad daily. I highly recommend it.

    The reset botton of the console not works or sometime hangs the game, every time i want to chage the game in a multicart i have to turn off the console and turn it on again. It cannot run sega 1000SG games.

    Works like a charm in my model 2 Genesis. Pause button is great, too!

    I have been using this with my Retron 5 and my favorite SMS game Phantasy Star. Works like a charm!

    I was hoping it would work in my JVC x'eye & it did playing Sega Master System ROMs on my JVC x'eye.
