    A must have for your SMS

    I love this thing. The SMS was my very first game console and this is the perfect companion! I definitely recommend the deluxe version, it's worth it!

    This device ran every game I thew at it without issue, regardless or region. Great device to use in a country that had a sub-par SMS selection.

    Exactly what I needed

    Excellent quality of construction and all features work as advertised. Save state support works well (same way as the Mega EverDrive X7). Some Master System games don't run correctly on a Genesis so this cart fills the gap nicely.

    Great flash cart

    This cart works amazingly. If you use it on your game gear, modify Master Gear with a switch on pin 42 and 43 you can also play game gear games.

    Rock Solid Flash Cart

    I have always been a Sega guy from the start. To be able to relive my childhood and experience games from all over the world with one cartridge and a few minutes of downloads is amazing. The only way this could have been better is if they were able to replicate the FM chip internally, but it's a small gripe. I will definitely be buying more Everdrives for my other retro systems soon.

    Master Everdrive

    Works great, but not a fan of the SG-1000 not displaying the colors right on all games, although that might be an isse with the games system itself. Overall, it works... get's the job done.
