Hi there i am kinda a noob in modding and repairing electronics etc. My question is about this 161 game cartridge which i bought new at the time. Problem is its too new or something as it seems getting stuck in my system often times so i kept the hardware of the cartridge opened without the cartridge itself to get it easier out of my mvs. But then i damaged a resistor my pictures are showing ( i can also post a video if you want), i tried to repair it by soldering the broken pin together to the interior which was crushed apart but it seems i killed the resistor with my very crappy soldering iron. However before i tried to repairing it and even after the game still runs, when i tried to put the game with the broken resistor fixed it obviously wont work and i get kinda a blue cryptic screen with this cartridge. So without its fine and it runs, but i would like to know what this resistor is for and where i can buy a new one it has number 221 on it. Is it harmful running your electronics and stuff like that if one is missing? As i am maybe planning getting a real aes system with a magic mvs adapter.
For the love of God, get yourself a new soldering iron with an actual tip! And that's a ceramic capacitor you destroyed, not a resistor.
It's hard to say what it does - presumably it's there to filter noise from some internal signal. The part is a 220pF radial lead ceramic cap with 0.1" lead spacing. This seems to be a good match: http://www.mouser.com/ProductDetail...=sGAEpiMZZMt1mVBmZSXTPPQUnq7ol7tGUi5FnunwJ4k= And I have to agree that you need a better soldering iron...
221 refers to it being 220 pF. These are cheap. Use a multimeter to check the voltage (if you want to buy a new one). You also could have soldered it on incorrectly or broke a trace or something like that. I don't know if you can find a picture of a "good" board to compare. My GUESS is that you won't damage the board, but that you might run into some set of games where the graphics or sound glitch out, but that's a complete guess based on the fact that the board appears to be working normally without it in. Without knowledge of how the board is wired, you won't know for sure. If the case is too big, maybe you should shave down the case a bit However, these carts are known to have thicker PCB's than normal. I'm not sure if the case is the problem here.
what is if i just sharpen the tip of my iron with a file, is that okey? Also is the Bioschip compatible with he Aes consoles? In my MVS as you can see in the Video you can just plug off the bios chip and put a new one in there without any soldering, i think the aes bios and mvs bios are identical.
No, according to this guy: http://www.neo-geo.com/forums/showt...IN-AES-SYTEM&p=3242222&viewfull=1#post3242222 it won't work. Even if it would, how would you put in quarters or set the dip switches? FYI: The AES bios is soldered in. If you are looking to get more features out of your AES, look up the universe bios: http://unibios.free.fr/ Installation isn't straightforward though, because it is soldered on the AES: http://www.mmmonkey.co.uk/snk-neo-geo-aes-unibios-install/
If it works without it, don't bother replacing it. <technical> It's used to prolong a signal's rise time. Also the MVS and AES BIOS are almost identical, there's a single flag which sets them apart. So if you put a MVS BIOS in an AES, it will believe it's a MVS--a defective one because the AES has stripped down hardware. The UniverseBIOS is more intelligent and should detect which system it's running on (plus let you "change" it virtually.)
It's possible, but I would strongly recommend against it. Most electronic soldering irons have tips made out of copper with a layer of iron plated onto them - if this plating is damaged, then the copper slowly dissolves into the tin in the solder. This has two effects - the first is that the exposed copper on the tip gets eroded and the second, more serious, one is that the solder becomes contaminated with Cu - which tends to result in brittle joints. Having said all this, for soldering a couple of pins on a coarse pitch through-hole device like that cap I'm sure it would work without any problems, but that still doesn't make it a good idea. Certainly don't try to solder SMT parts using an iron with exposed copper...
Wow, so much to say. First off "Hi!". 1 - New soldering iron (RadioShack) 2 - Buy at least one spare tip 3 - Buy a desoldering Iron (RadioShack) 4 - Buy at least one spare tip 5 - Desolder out the capacitor 6 - Buy a replacement 7 - Solder in the new one I think you're confused on the MVS/AES, plus I'm a little confused on what you have (AES or MVS). The MVS you have in the video is a MV1FZ, which can be used with the UniBios. Which can be installed in your rather easily. The Unibios let's your AES unit do AES or MVS If you need help with this and leave in the US, I can help. Wynd
technically that depends on the iron tip if its copper then YES you can if its enamel coated then NOOOOOOOOO you will ruin the tip and need to buy a new one another option is to buy a new tip if your iron allows tip removal
I can replace the tip, i will delay this whole soldering project for another time when i have some money buying new tip and desoldering Iron etc like wynd listed up. But does any one know how can i fix this (pic below) when i hook up my neo geo mvs to my small tv? I want to play it on my old television because the games just look better than on a lcd hd tv for me, i also can hook the sound cable to the old tv and it will play sound. But the problem is the blue lines you see are black and on the top left a bit of the screen is missing. I tried everything out so far like test screen but i cant do anything to fix it. Is there a way the mvs system can do something to fix it?
Your TV needs adjusting. The only other option is to delay sync horizontally and vertically, which would take a semi-complicated custom logic (or microcontroller) circuit.
