    Amazing - BUT, needs warning

    Posted by Domarius on Dec 28th 2022

    This is the most amazing way to re-live my childhood, trying out all those games that I may have seen briefly for one weekend when hiring them out but wondered what it`s like to actually complete them, and even try ones that we couldn`t hire! Emulation doesn`t trigger the nostalgia. Playing it through a real CRT TV with frame perfect playback (due to actual hardware) and a real controller, that hits me with nostalgia every time! But with the amazing convenience of the Everdrive I can browse a huge library very quickly without taking up real world storage space! And save state to boot (which I`ve never actually done yet).


    On the FIRST run, you will get a message saying the battery is dead. If this continues to happen AFTER the first run, the battery is actually dead and replacing it will fix the issue, but you will get the message ONE more time after installing the new battery. Something to look out for.

    Secondly, I highly recommend ordering the included SD card when placing your order. This will save you the hassle of potentially getting an incompatible card. I bought a brand new, legit 32gb SanDisk (the smallest I could purchase) from the local OfficeWorks, and perhaps the card is too big? It kept saying ``SD Card Not Found`` and yes I formatted it using the tool, following the instructions. What fixed the issue is I dug out a non-branded 8gb SD Card I had laying around from a bulk eBay order, and after formatting, this card worked.

    The last flash cart you will ever need for your master system.

    Posted by Ryan Arnold on Nov 28th 2021

    This is a flash cart that will allow you to play master system games (and even some game gear, sg1000, and sega card games) on your master system. I have used it on my Mega SG and my Master System and never had an issue. It seemed to work with any SD card I plugged in. I am very happy with it. If you need a flash cart for your master system, this is the one you want!
