Differences between the new version and the old version:
Thinner, lighter, slightly brighter screen,
Supports TV output, battery capacity is smaller, version 3.60
That’s pretty much all the changes. The UMD port is manual instead of pop-up. There are some changes in the arrangement on the sides. There are more color choices and the cost is lower. The back is no longer matte but the same hardness as the front. It’s become harder to sell, and prices have dropped.
Version differences:
The version asked by newcomers generally refers to the original sales area code of the machine. The area code is a set of numbers at the end of the barcode on the front and side of the psp. At present, the common machines in Shanghai are 1000 Japanese version, 1001 American version, 1004 European version, 1006 Hong Kong version, and 1007 Taiwan version.
Japanese version: Among these versions, the 1000-Japanese version has the smallest quantity. When buying it, be careful that it is an old and refurbished one. Many newcomers think that the Japanese version is the best. In fact, the hardware of the machines is the same. The parallel import of the Japanese version into mainland China was the earliest among these versions. The machines are the oldest and the possibility of easily buying old machines is also the greatest.
US version: There are rumors on the Internet that many of the 1001 US versions are factory refurbished. Generally, the way for novices to identify is to open the battery cover and look at the label under the battery. Factory refurbished machines have an English "RE*******" label, which means that the product was returned to the factory for repair. In fact, the quality is average. There will be no problem. It is also a new machine, but buyers will not accept it. Nowadays, large and reputable game stores in Shanghai generally do not sell such machines that have been returned to the factory. So even if it is the American version, there is no need to be nervous. Just check to see if the machine is in good condition and look at the labels inside.
European version: In fact, the quality of the 1004 European version is still very good. The quantity in Shanghai is not large. After using it myself, I feel that it is no worse than the Hong Kong version.
Hong Kong version: It is generally believed that the 1006 Hong Kong version of the machine is the best, but when you buy it, it does not mean that everything is ok when you see the Hong Kong version. Many js take advantage of your mentality to do tricks.
Taiwanese version: The overall feeling of the 1007 Taiwanese version is average. The advantage is that it has the same Chinese manual as the Hong Kong version.
Recommended versions: 1004 European version and 1006 Hong Kong version
2. Is it better to hard downgrade or soft downgrade?
The first thing I want to say is that if you buy a PSP, you must buy a machine downgraded to 1.5. The reason is very simple. A 1.5 machine can do everything and implement the most comprehensive functions, while a machine with a higher version basically You can only play high-priced genuine games. But newcomers don’t know the difference between hard drop and soft drop, let alone how to detect hard drop or soft drop on the machine.
Hard downgrade: Hard downgrade is to open the PSP case and refresh the chip information on the motherboard to achieve the purpose of downgrading.
Soft downgrade: Soft downgrade is achieved through software vulnerabilities in the PSP system.
As you can see from the above, the biggest difference between hard drop and soft drop is that hard drop requires the machine to be turned on. Even hard drop can be perfect. I think everyone will choose soft drop. In addition, many hard-downloaded machines will encounter the problem that some games cannot be played online. So it must be right to buy a soft drop.
You can ask the boss if it is a soft download. Generally, the bosses of large game stores do not need to lie to you. Some stores even use brand-new machines to soft-downgrade in front of you. If you are not sure, then after you get the machine, open the UMD optical drive, and you can see a little green circuit board exposed on the top of the inside of the host. That is the motherboard. There is a series of small hot stamping codes on it. You can see it clearly if you look carefully. Yes, for newcomers, just remember that the motherboard numbered IC6001 is a soft downgrade, and the motherboard number IC1003 is a hard downgrade motherboard.
3. How to choose a psp LCD screen?
Large game stores can usually help you choose a machine, mainly the screen.
There are very few truly perfect screens out there (without any bright spots or dead pixels), so generally don’t make too high a request in the hope that you can buy a perfect screen through selection. Merchants are not fools either. Machines with perfect screens will be singled out to improve a certain level. The price is low, and not all stores have perfect screens available, so they are rare.
Everyone needs to understand two points.
First of all, you must know that bright spots and bad pixels are different concepts, and bright spots are not bad pixels. If you buy a Hong Kong or Taiwan version of the machine, you can read Sony's official technical standards in the manual: it is normal for the number of highlights to be less than 3. Bad pixels are different. As the name suggests, dead pixels mean the screen is unqualified.
Then how to judge bright and bad pixels (including dark spots). Ask the store to turn the screen to completely black (a black screen when the power is on and does not display any information). At this time, take it to a darker place and look at it. There will be a pixel-sized spot on the screen that is brighter than the surrounding area, which is a bright spot. The most common one is White or red dots. It is very easy to judge dead pixels (including dark spots). Under normal screen conditions, pixels that cannot show color are dead pixels (including dark spots).
1 to 2 bright spots will not affect the normal display because they are basically invisible during use. And dead pixels have an impact, because dead pixels cannot display images.
BZ’s suggestion: When buying, choose one with fewer bright spots. The fewer the better, usually 1, and the best position and brightness are not obvious. If you see bad pixels (including dark pixels), then you must not buy it! It’s equal to a defective product!
4. How to judge whether it is a refurbished machine?
This is the most worrying question for all newcomers. Here are a few simple tips for you.
1. Check whether the number on the machine is consistent with the one on the outer packaging;
2. Open the battery cover and check whether the label on the main unit has any traces of being tampered with. Mainly check At the bottom, you must peel off the sticker below to open the machine. In addition, factory refurbished machines have a special "RE************" label, which can be identified at a glance. The machines used by merchants to sell hard products will also move labels, so this is one of the reasons why we don’t recommend buying hard products.
3. The condition of the machine must be 100% new, without any scratches or wear marks.
4. Take a look inside the screen of the machine, between the key gaps and other places where dust can easily enter. There is not a single particle of dust on the new machine.
5. All the packaging of the new machine is brand new. Each accessory is packaged in a special small bag with a seal or adhesive tape on it.
5. The most vulnerable to being chopped Things: Accessories
Sometimes if you ask for a deluxe version, the merchant will give you a regular version console with deluxe version accessories. In fact, this doesn't matter, because there is no difference between the regular version and the deluxe version of the machine itself, but everyone needs to be aware that some JS will use counterfeit accessories to kill you. Generally, large game stores with good reputations are less likely to mistake counterfeit products for original products, so it is very important to choose a store.
The difference between original wire-controlled headphones and counterfeit ones: Look at the back of the wire-controlled headphones. In addition to the words MADE IN CHINA, the original ones also have many lines of words, including a psp-120 wire-controlled model; the counterfeit wire-controlled headphones There is nothing behind it. The original headphones and wire control are packaged separately in two small bags, please pay attention.
The difference between the original cloth cover and the counterfeit one: the original one has the Sony trademark on the upper left side of the front, and the seam around the cloth cover is directly below; the counterfeit one has no trademark, and the seam is on the right side.
About other accessories:
Good stores generally do not recommend a lot of accessories. If any boss recommends you to buy a lot of peripheral accessories, it must be JS! Because profits from parallel imports of PSPs are average, if I want to kill you, it’s peripheral accessories!
If you are generally afraid that the machine will be damaged when you take it out, you can buy an imitation logic hard case. Please note that it is imitation logic, not original logic. Original logic is very rare, and the workmanship is very, very sophisticated. It’s definitely not just a transparent plastic box with a rubber lining! If any boss tells you that there are more than one hundred original logic hard boxes, you can walk away without looking back! A super big JS can be sold for hundreds of dollars for 25-35 yuan...
There is also an external battery. In fact, most people don’t need to buy external batteries. There are usually two types of people who need external batteries. One is those who often attend online gatherings (such as hunters like us), and the other is those who take it with them on business trips. Generally, external batteries are made in China. The principle is to act as an external mobile power supply. The workmanship quality cannot match that of the small P. It is for emergency needs, so don’t use it too frequently. Nowadays, the highest nominal capacity is 8000 mAh. In fact, it is far less than that. The price of 8000 capacity is about 75-80, and it is JS that offers more than 100 yuan!
Generally, for domestic peripheral accessories, you can check the prices on Taobao first, which is a good reference.
I would like to ask what is the code on the box of the PSP I just bought?
