NeoSD Pro MVS

Posted by 0xdeadbeef on Jun 22nd 2024

Be aware that this is not the same hardware as the NeoSD Pro from previous batches. They changed the FPGA, so the new NeoSD Pro needs a totally different firmware and the current one is not really final yet. Also, be warned TerraOnion is a company with almost non-existing customer support. They simply never answer any request by mail. Your only hope is the Discord channel and even there you need a lot of luck to get help. And there are quite a few people who have smaller or bigger issues - graphical glitches and crashes are quite common. Generally speaking: it doesn`t seem to work with every hardware and from there on, you are more or less on your own.

Also loading games into the RAM slot takes pretty long for large games. And flashing a large game into a slot take even much longer.

This being said, I`m pretty happy with my NeoSD Pro MVS on my MV2F board. Thanks to SAG, I have the newest firmware that is not available yet on the TerraOnion site as it`s supposed to be experimental. I tried dozens of ROMs now and all the classic games worked fine, also new things like Cyborg Force worked without problems.
I still had a few crashes/freezes now and then, especially with the the 51 NeoCD games, but all in all my NeoSD Pro is pretty stable and I can usually play for hours without any issues.
Speaking of NeoCD games: they work in principal, even Samurai Spirits RPG, but there are crackling noises during CD load operations and the CD games are generally somewhat unstable.
The SD card support is a bit flaky, too. Originally, only Kingston cards worked, since firmware 1.08 R07 more types are supported but still some don`t work at all.
Also adding new games to the card later partially doesn`t work unless you sort the directory with an external tool like DriveSort. Plus, there seems to be a limit of 321 NEO files that can be handled.
Last but not least, some demos etc. that work in MiSTer don`t work. E.g. the demo ``Bad Apple`` (which technically seems to use two slots) doesn`t work correctly when started from the RAM slot.

What is great about the NeoSD Pro is that you can define SoftDIPs for every game (e.g. to enable Blood in Metal Slug with US BIOS). It can also store high score data etc. on the SD card. Also, changing back to the NeoSD Pro menu works even with an inserted Memory Card which annoyingly doesn`t work with the ``161-in-1`` cards.

You can activate an in-game menu to reset (soft/hard) the device, change the (flash/RAM) slot or enter a cheat code. Obviously the in-game menu causes glitches for some people but it works fine for me. The cheats database seems to be inferior to the one in UniBIOS and is therefore somewhat futile for UniBIOS users but as the region selection and AES/MVS selection this is surely nice to have with an original BIOS.

Anyway, even if TerraOnion is a terrible company and the card is expensive and picky, it`s a great piece of hardware when it works.

Must own

Posted by Auron on Jun 23rd 2024

I haven’t had any issues with my CMVS and 2 slot MVS. Some people have had issues. It works pretty well when it does. Like the NGPC, there’s really only one game in town that’s being actively produced.

It’s also great that you can play homebrew neo geo titles on it pretty easily, especially with all the recent releases. Definitely recommend it to anyone, if they’re ever produced again.

What a greatest product ever seen including StoneageGamer support!

Posted by Hai-Seok Lee on Jun 9th 2024

Neo SD Pro MVS!!!
That is amazing game gear ever seen it before including Stoneage Gamer`s fantastic support.

Art of Fighiting which is Neo Geo`s first 100 Mega Shock game released at 1992, It gave me really shock. I wanted to play it at home, but NeoGeo and Art of Fighting were too expensive. I was young and very poor to buy it.

With the development of PC emulators, Art of Fighting was playable on my PC.
But there was a sense of alienation from what I used to do in the arcade center.

Eventually, I got a CMVS which is a customized arcade MVS in 2022 and bought the 161 in 1 gamepack with it, but unfortunately, it didn`t include Art of Fighting.

While I was lamenting, someone told me about the Neo SD Pro for sale on Stoneage Gamer.
I visited the website a few times, only to see that it was sold out, so I left a message to let them know when it became available.
In June 2023, Stoneage Gamer told me that they were taking pre-orders for the NeoSD Pro, so I pre-ordered it right away.

I expected to receive it in December 2023, but it was delayed twice and I finally received it in May 2023.
I was frustrated when I plugged my SD card into the NeoSD Pro and turned it on.
A messed up screen, no SD card recognized!!!!
I think I was more frustrated because of the long wait time.

I started talking to Andrew Harsh from Stoneage Gamer to get some help.
It was difficult to get an immediate response due to the time difference between Korea and the US, but Andrew spent a lot of time with my frustration and gave me the answer.

Today I play as Ryo Sakazaki and use the Haow-Ken to save Yuri.

Thanks to Stoneage Gamer and Andrew Harsh.

Dear
Hslee.

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...
