The NeoSD AES allows you to load your game back-ups (commonly known as ROMs) on a microSD card, put the microSD card into the NeoSD AES, put the NeoSD AES into a Neo-Geo AES system and have your list of games at your finger tips.

LOADING TIME NOTICE: Keep in mind that they are for switching games. If you turn the AES on with the cart in, it will instant-boot the last flashed game, as the flash memory is non volatile, and it appears as standard roms for the AES. That means that you can turn on the test mode dip, boot the mvs and enter the soft dips and configure them from the bios as with an standard cartridge.

    Hello everyone I am French, I apologize in advance if my comment is badly written or badly translated I would like to buy this product because my boyfriend found a Neo Geo last month, it's the console of his childhood, he had dreamed of it for years. I think this Neo Sd Aes would make him very happy for Christmas. Being a little younger than him, I don't know this console, but I really want to play it and discover this world. Thank you all for reading me and have a good holiday season

    I'm really happy with this purchase. I might help some people out there that are in the same situation I was in, I was waiting for the Darksoft cart or the neoSd pro to get in stock, when I realized they weren't coming back any time soon I just bit the bullet and bought this as a last resort.

    I've got zero regrets. This does everything I want it to do, and I seriously don't care at all about the extra ram slots because I don't know what I want to play until I decide to play it. The load times mean nothing to me as they're reasonable... I just pick the game I want, get up and go to the bathroom, and when I come back it's ready to go. I'm actually really happy I didn't spend 700 bucks on the pro as this works perfectly fine. And as far as flash carts go, I love how this one works- being able to sort games by genre is awesome I wish all my other carts did that. Bottom line- if you are holding out on the Darksoft or the neoSd pro like I was... Don't bother, save some money as this cart is great and the load times are minimal and not even worth complaining about. The neo geo has like 150 games top.. you know what you wanna play once you get it loaded and it runs perfectly.

    ESSENTIAL for every AES fan that's not a billionaire

    Posted by Ryan Costello on Nov 10th 2021

    Exactly what I was looking for. I love collecting AES carts, but many are too expensive for me to realistically ever own. The NeoSD allows me to have access to the full library, but play on my AES console with original controller. Works perfectly with all games. Takes about 30-90 seconds to flash games depending on the size. Can't recommend this enough for any neo geo fan.

    Needed Accessory for a Neo Geo Owner

    Posted by GamerDude44 on Nov 8th 2021

    This is an absolutely needed accessory for a Neo Geo owner, this plays all the games so fast and awesome. The interface is awesome and easy to use and the thing just works well out of the box.

    Absolutely fantastic

    Posted by Sayaka on Oct 26th 2021

    I'm very satisfied with this flashcart, and couldn't ask for much more than this. I honestly don't think having slightly faster loading times or 4 slots is that much of an upgrade. This is perfectly fine as it is. The game compatibility is what counts in my opinion. I'd recommend this any day.

    Hello, I got to buy and play to this NEOSD AES for years now. It still works perfectly on my European NEOGEO. I have many different retro console too. I can tell you that this piece of hardware is one of the most valuable gear I have so far. Also I can download and use home-brews and bootleg games with it. Beside that if someday i will have to get a bit of money back from my other older NEOGEO AES genuine cartridges then i could sale those ones because I know that I can still play with the NEOSD AES that I would keep as my last game cartridge. Well overall this is Good fun to own this kit and easy to use. Great Buy experience on this webstore. Thank You again Stoneage Gamer & Terraonion !

    NeoSD AES

    Posted by Dennis Plester on Jun 23rd 2021

    The NeoSD AES, like the NeoSD MVS I purchased previously, works exactly as expected and perfectly meets my needs. I like to have my old consoles set up so I can plug them in, fire them up and have access to my library without changing cartridges, so I can keep my collections in their boxes and on display.

    Some might find only having one game instantly playable at a time to be a bit restricting, and if that is the case, go for the Pro version instead, but it does not take that long for your next choice to flash across, and I tend to start a game intending to keeping playing for a while anyway. The menu system is relatively simple but works well.

    The NeoSD series can seem expensive compared to flash carts for other systems, but are worth it when you consider the convenience and the relative value of game cartridges for the system.

    More Than Satisfied

    Posted by Serge on Jun 15th 2021

    The NeoSD is an amazing piece of tech. It works flawlessly on my Japanese Neo Geo AES. I am very thankful for these niche products as their availability is never guaranteed. Anyway, leave the Pro model for the pros, this is plenty cartridge as it is. I do not believe that improved flash times, extra slots, etc. will make the experience much better. For those simply determined to play on the original console, the NeoSD is a solid way to go. I am more than satisfied, borderline giddy with this cart! I think Sengoku 3 is calling me. Gotta go. Happy gaming, retro gamers

    NeoSD - My introduction to Terraonion

    Posted by Oliver on May 19th 2021

    Let me start this review with the fact this was my first Terraonion product. I always thought Terraonion was too expensive and I will never buy such expensive products for my old retro systems. I was soo wrong...
    One day I decided to buy the NeoSD because I wanted to use my Neo Geo. Before that it was collecting dust, because the games were just too expensive for me.
    So when I finally received it in Germany I tested all these games I have never played before. I was surprized how good everything was. The games were incredible but after all I could only test them thanks to the NeoSD. What an incredible device it is. Every game worked perfectly. Only once I had graphical glitches but when I restarted my Neo Geo everything was fine. I own this device about three months now and I love it. Now I really think that Terraonion products are actually worth the money. I was convinced and also bought the Super SD System 3 and the MegaSD. Don't make the same mistake as I did and label Terraonion as too expensive and not worth the money. These products are perfect!
