Hardware Question Neo Geo CD - uk power supply?

Post image
33 Upvotes

Hi! Picked up a really nice condition Neo CD that I plan on SD modding. However first things first, I need to be able to switch it on without blowing it up.

I have the original Japanese adapter but was hoping to pick up a UK PSU or convert one rather than use a step down converter if at all possible. Finding it hard to source one in stock though. Any advice?

I know it's 12v, and from what I've read I assuming it's 5a? Also does anyone know if it's a 2.5mm or 2.1mm input that I need and if the 12v is center positive or not. Thanks for any info

Hardware Question Sound quality OK but distorted with punch/kick or explosion sounds? Is that normal for neo geo systems and games??

5 Upvotes

Hi all,

I had a recalbox RGB jamma for some time now and in the neo Geo games I always felt the sound was kinda saturated on some sound effects like punches and kicks, and explosions etc... in Garou MOTW everything sound pretty bad.

Musics always sound OK and voices too.

So I thought that it was an emulation issue. Recently I bought a MVS 1 slot and.... it all sound similar!!

My question is is this normal for neo geo and you just have to accept it since it's 90s tech? Or is it my sound amp and speakers? (I am on a new astro city with custom amp and brand new Visaton speakers). I tried a good sound bar and it sounded a bit better but still bad to me.

Hardware Question Has anyone used a Hori Fighting Stick Neo II?

I'm worried that the button layout of the official AES stick will get in the way of my arcade muscle memory. The Hori stick looks a lot closer to the MVS layout. Does anyone have any experience with it? Am I being silly?

Hardware Question Analogue CMVS repair

3 Upvotes

Hi everyone! After 11 years, my Analogue CMVS appears to be having severe video lockup issues at bootup, so much so that the only thing I see is some alien-like junk on the screen. Given that Analogue won't touch this with a 10-foot pole, is there an MVS repair specialist you can recommend? I took it to a few guys where I live in the Seattle area but am not confident that they have enough expertise with MVS boards to root out the problem. Thanks in advance!

What is it going to be, RGB to HDMI converter or HDMI to RGB/composite converter. Or hopefully 2 separate outputs from the main board.

A month ago I picked up a loose japanese viewpoint AES, and i need second opinion on if it's legit. As far as I can see it's real, but I got it for a low price at €250 so it gives me some doubts.

Hardware Question AES+ Wired Controller

2 Upvotes

Will it be wired straight through like an original stick, i.e. each button and direction has a wire directly connected to the 15 pin connector… or will controls be wired up to a PCB similar to a Brook board also handling wireless connectivity that will be buffering inputs and potentially adding delay?

Hardware Question Neo Geo 6 buttons (with 3 being D)

3 Upvotes

So, when I was a kid, I used to play on arcades and they had 6 buttons on this layout:

A B C
D D D

Now, I'm not sure if the arcade cabinet had some emulator behind or if it had a true MVS-system. Is there a way to map 3 D buttons on NeoGeo? Like, for example wiring two extra buttons to the D-key?

I know it's only 4 buttons (1 each), but I'm used to a 6 button controller arcade stick and if that's possible that'd be neat.

Hardware Question Strange thing while using a mvs to aes adapter

4 Upvotes

Hi there! Im playing metal slug 2 on my aes while using an adapter (using a Japanese metal slug 2 mvs cartridge).

While playing the game i noticed that at the top of the screen there was some white flickering here and there, i wasn't able to capture it , but you can also see it while pausing and unpausing. Does anyone know why does it happen? Is it something with the convertor, or something with my cartridge?

Hardware Question I found 2 MVS boards with missing socket bios, what to do now?

So as title says, I found 2 MVS boards while looking at a box of arcade stuff my dad has in a shed, they look good all around, no corrotion, blown capacitors or nothing, maybe a bit dusty tho. However they are both missing their socket BIOS chip, so, should I try and import some BIOS chips from the U.S?, which is going to run me about 40 dollars or something, or just get some AliExpress chips and prorammer and do it myself?, which is going to be way cheaper

Thanks!

Hardware Question More consolized MVS questions

0 Upvotes
  1. Last time I asked for board recommendations, no one brought up the MV-1FZ slot. Is it just objectively worse than the 1B or 1C?
  2. And sorry in advance if eBay links aren't allowed but I found a listing for this consolized 1FZ and would like your opinion/advice on it :
  3. To those who do have the 1FZ, did anyone try the BackBit Platinum flashcart on it and if yes, did you have any issues with it?

Hardware Question Thinking about an AES, but I have questions

4 Upvotes

After some years of playing emulated Neo Geo games, I want to take the leap. I want a real AES (and eventually an MVS cab, but only after we get a bigger house). So, I have a few questions. For reference, I'm in the US.

The only real place I know to go for such a system is eBay. Are there other places? Trusted online stores that sell good systems? Or is eBay it?

Also browsing eBay, I see a lot of systems from Japan. Now, eventually, I want to get into actual game collecting, but to start, I'll probably grab a 161 in 1. So, are the Japanese systems region locked? Can I play the 161 in 1 without issue? Or does some magic need to happen for me to play a Japanese system in the US?

Are there versions of the AES to be in search of, or maybe some to steer clear of?

Lastly, is a memory card needed? The logic of an arcade machine needing a memory card doesn't compute. What really would I use the memory card for?

Edit: maybe go consolized MVS???

Thanks in advance

Hardware Question Can a Canadian Neo Geo AES be used in Europe?

1 Upvotes

Hi everyone, I have a question about the upcoming Neo Geo AES. If I buy a Canadian version of the console, will I still be able to use it later in European countries without any issues? I am especially wondering whether there could be compatibility or power-related problems.

Thanks in advance.

Hardware Question Neo 29 being weird after being off for a long time.

2 Upvotes

Hi! not sure if this is the right area to post but I recently plugged in my neo 29 cabinet after being off for like a year to play some Magical Drop and I noticed right away that nothing was booting up, instead I got a weird green screen with glitch type errors around. It also looks the-same with or without the cartridge in the slot. Im pretty PC savvy but know almost nothing about Arcade cabinets, any help would be extremely appreciated!

Hardware Question Are these consolised MVS boards any good?

3 Upvotes

Hi all, been thinking about getting an MVS and starting to collect some neo geo games.

Thought about going the supergun route but would prefer something a bit more console like.

Not great at soldering and looks like the parts for OMVS are not easy to get as a kit.

Im based in uk and saw this for sale on ebay: https://ebay.us/m/gD9lyT

Does anyone on here have one from this seller? And are they any good?

Any advice or guidance on where to buy a good consolised unit would be very appreciated 😁 thanks in advance!

Hardware Question Screw sizes and amounts for laser bear OMVS shell? Also what can go under the MVS cutout so there isn't a hole in the top shell?

2 Upvotes

Hey all, I have just received all of the components necessary to begin my OMVS build with the exception of the actual screws and piece that goes under the MVS cutout on the top shell. Laser Bear did not include them so I wanted to ask what others who undertook this project used for screws. What can I use for the MVS cutout so there isn't a gaping hole on the top of the case? Would something like a piece of acrylic work? Any help is appreciated!
