    The Ultimate Boutique Multi-Cart for MVS

    Posted by Jesse H. on Oct 20th 2021

    If you’re looking for a flash cart for your MVS (and you’re lucky enough to find this in stock), look no further. It may cost a pretty penny, but the NeoSD Pro is absolutely the best option on the market for MVS flash carts.

    Flashing a game to one of the four dedicated ROM slots is a breeze and ensures the game will look, feel, and sound identical to the original cartridge. Having access to home-brew and patched ROMs enriches your game library and adds value to your MVS.

    The real value, however, lies in the menu. It has a clean and intuitive UI design, giving you easy control over your experience from boot menu, region, and MVS/AES options to in-game cheat menus and debug modes. There is even a jukebox mode for the really hardcore Neo-Geo fans.

    The downsides are few, but notable. Obviously it’s an expensive product, but I feel like I’m getting more than my money’s worth considering the rising scarcity and relative unreliability of original MVS carts. I can play my rare games without the fear of damaging my 20 year-old cartridges. The included .neo file conversion tool isn’t exactly a dream, there is no comprehensive user manual, and Terraonion’s customer support never got back to me when I had a question before I purchased my NeoSD Pro. Other than that, it’s everything I wanted and more.

    In contrast, I would love to give Stone Age Gamer a shoutout for their excellent service. I asked to be notified when this came in stock and got an email as soon as it was available again. Shipping was speedy and my cart was packaged securely. You can tell that this company is run with integrity by people with a real passion for retro gaming, and they have made a customer of me for life.

    Tl;dr: Buy the cartridge, but only from Stone Age Gamer.

    amazing product for a consolized MVS

    Posted by Jordan B on Oct 3rd 2021

    this thing is absolutely fantastic, it adds nearly all the features of a unibios without actually needing one (though still works with one just as well), can organize your games by genre and favorite categories, plus it has the ability to keep 4 games stored in memory, while the flash memory slot it has loads super quickly which is nice for trying out different things.

    Neo SD Pro MVS

    Posted by James H on Sep 1st 2021

    Excellent flash cart for the Neo Geo MVS. It lives up to all the hype. I havent had any difficulties with it. It is expensive, but if you want all the bells and whistles this is the way to go. Recommended.

    NeoSD Pro only half works

    Posted by TS on Jul 29th 2021

    One of the features I was looking forward to with the NeoSD Pro was the RAM slot that loads games quickly unlike the comparatively slow flash slots.

    Unfortunately, there seems to be a bug (reported elsewhere and even in pre-production reviews on YouTube) whereby the game in the RAM slot quickly loses some or all of the audio while playing. I actually thought it was my MVS and went through a lot of hassle trying to diagnose the issue until I caught a mention of the issue in a YouTube review...

    Until that gets fixed, it's only 2 stars since I'd expected it to work and the RAM slot bug looks to have been known for awhile...

    Very interesting cartridge. Stoneage- customer support amazing! TO- needs a little hand.

    Posted by GS on Jul 22nd 2021

    Overall, the cartridge is very neat. Does what it's supposed to do. I like the case and clamshell. The only interesting bits is the format the games need to be in and support for different motherboards. Some MVS motherboards I've tried just don't like the cartridge at all. TO customer support seens to put that on the customer. Due to the nature of the hobby- I understand- but there's also a tactful way to get your point across. We've tested a TON of motherboards and hardware- and we're not novices by any stretch- and sometimes some of these cartridges just don't like them, so possibly be prepared to hunt a few just in case. Either way- cartridge is very cool, just be prepared for a little work and don't come in to this expecting customer support from the producer. As far as Stone Age goes- they've always gone above and beyond and are a great company.

    A Powerhouse Flashcart

    Posted by Steven Williams on Jul 20th 2021

    Fast intuitive menu interface runs most roms. Comes with 5 slots including a ram slot that load most games in no time. The 4 other slots store games for instant boot. With FPGA implementation all games run smoothly identical to the originals.

    Comes with dip settings and cheats that can be dumped. The cheats you manually have to hunt down on your own and have them placed on your sd card. The soft dips are cool but I think they apply across all games so adjust accordingly. The cart enables you to save high scores to your sd card... the cart doesn't allow for transferring your full gamesaves to the sd cards which I found disappointing. You'll have to make due with only transferring scores.

    Be careful when inserting the cart because for some CMVS systems the cart goes in backwards. I had to open up the shell and turn over the pcbs to match my analogue CMVS. This feels like a hefty cart. It's got a lot of horse power. But it's very expensive felt like I was buying a car. Overall a solid cartridge much better than the 100 plus repos floating around on ebay.

    Great Device!

    Posted by Spencer on Jul 17th 2021

    When paired with Unibios 4.0, the NeoSD Pro is the ultimate Neo Geo experience. Easier as it seems to set up and I cannot recommend this enough!

    Great product from Terraonion

    Posted by Shuofan Chen on Jul 5th 2021

    This is definitely a must-have for retro Neo-Geo fans. I got the MVS version which has the best value for money. MVS boards can still be easily found and you can consolize it with a c-box. NeoSD Pro supports more than 50 Neo-Geo CD titles including all 8 CD exclusive games. The loading time is insanely fast and 3-4 times faster than NeoCD SD Loader.from my test. With NeoSD Pro, you can enjoy full Neo-Geo library in one single cartridge, and there is no similar alternative on the market. This is an substantial investment, however it’s absolutely worth it.
