I hope that before you buy a good understanding of the PSP, ithouch related knowledge, so that buy will not regret.
Finally, I recommend a format conversion tool that I think is very good for converting video on PSP and other mobile devices. It's called Format Factory
PSP Cracked in layman's terms
Colophon
Have you heard that PSP can be used to play cracked games, but you've never been able to figure out the ins and outs of cracked games, or you just don't know what they are? How did cracked games come to be, and what is their history? Now we will tell you, the knowledge is deeper, to have a long paragraph oh, ready we start.

How PSP's licensed games work
PSP's licensed games are called UMD disks. UMD is a disc format customized by Sony for PSP. UMD is a CD-ROM format customized by SONY for the PSP, and all PSP licensed software and games are shipped on UMD. (UMD, boot disk, and boot UMD are the same thing, collectively referred to as UMD below)
How to play cracked PSP games
The so-called cracked PSP games are to download a kind of ISO file from the Internet, and then copy it to the PSP's memory stick to run. (Pirated games, cracked games, ISO games are the same thing, hereinafter collectively referred to as cracked games)
How to play cracked games on PSP
The principle of playing cracked games is to export the contents of the genuine UMD into an ISO file (a kind of CD-ROM image file) that can be copied on a memory stick, and then uninstall the PSP's original operating system. Then the original operating system of the PSP to find ways to uninstall, install a special system that can play the ISO file. In fact, it is very simple, a **** on two steps, one is how to export the ISO file. This problem has been completely solved, do not need to worry about us, the Internet will be constantly updated, generally we can download. The other is how the special system is installed on the PSP. This is a very complicated thing, we will focus around this below.
System Firmware Concept for PSP
The whole process of installing a special system is called brushing. A **** is divided into two steps, the first is to find a way to uninstall the original system, known as downgrading, and the second is to install the special system again, known as upgrading. Currently there is also a one-step brushing process, which Roger will introduce to you later. First let's talk about downgrading, why call it downgrading? This starts with the history of the PSP hack and to understand what is the system firmware of the PSP.
The PSP is a multimedia platform, just like a computer, where you can play games and watch movies and listen to music. Everyone knows that with a computer you have to have an operating system (like windows), and like a computer, the PSP has its own operating system, which is called the system firmware on the PSP. (By now, everyone has the concept of system firmware)
The concept of upgrading and downgrading
When the PSP was first launched, its system firmware version was 1.0, and at this time there were no cracked games. Soon SONY introduced an official upgrade program in order to increase the functionality and enhance the stability of the system, and by running this program, it was possible to upgrade to version 1.5 of the system firmware. It was on this 1.5 system that the PSP was cracked and could run games in ISO format directly from a memory stick. Soon after SONY announced a new official upgrade program and updated the system firmware to 2.0. since 2.0 was very different from 1.5, cracked games could not be run on the new system. once SONY learned of this, they turned the system upgrade, which was originally intended to increase functionality, into a means of resisting piracy. (By this point, everyone had the concept of an official upgrade program and a system upgrade)
As SONY upgraded the PSP system, hacking teams continued to crack its system to allow it to run ISO games. Once the new system is cracked, the hackers publish a downgrade program and an upgrade program. As I said before, the principle of bricking is to find a way to uninstall the original system and then put the special system on. At that time, the special systems were all modeled after the 1.5 system firmware. Therefore, brushing at that time was to downgrade the new system to version 1.5 and then upgrade to a special system that could run ISO games. (By this time, people have the concept of system downgrade and hacking program)
Following 1.5, SONY officially released systems roughly: 2.0, 2.71, 3.03, 3.10, 3.52, 3.71, hacking cracked system firmware roughly: 2.71secn, 3.03oec+, 3.10oear+, 3.52m33-4, 3.71m33-2, etc. Generally the purely numeric systems are official SONY systems that can't break solved games, and the numeric plus letter combinations are special systems that can run ISO games. (So far, everyone has the concept of official and special systems)
The concept of soft and hard drop
In this way, SONY releases a new version, the hacker spends effort to crack one so that it can drop to 1.5. But the latest system is always in the state of being cracked. Let's say, SONY released 3.03 system, the hacking team spent some time to crack 3.03 (hackers are not gods, it takes a lot of time to crack), SONY learned and immediately released 3.10 (this time is very short, because SONY technical power), the hacking team will start to crack 3.10 again, the player is again a long wait. In this state, the latest system is 3.10 (cracked, can not be downgraded to 1.5), but can play ISO games only 3.03 (cracked, can be downgraded to 1.5). What's worse, SONY now states that once a new system is released, all previous systems are discontinued, and all new consoles have to be pre-installed with this new system bundled together. This makes previously released machines that can be cracked very desirable. We call these machines that are shipped with a pre-installed cracked system and can be downgraded by running a hacking program a soft downgrade machine (3.03 in the example). So what to do with 3.10, the hackers came up with another solution. Instead of using a program to downgrade, the machine was disassembled, the chip was unplugged after being blown through a hot air blower, then connected to a programmer to be flashed, and then reinstalled on the PSP motherboard. This way the chip is replaced with the same as the pre-installed cracked system of the machine, and can be downgraded through the hacking program again. We pre-installed with the system has not been cracked together with the release of the machine, and by removing the machine to brush the chip to downgrade the machine is called a hard drop machine (example of 3.10) hard drop in the process of dismantling the machine, there may be damage to the PSP motherboard or the chip, resulting in the quality of the PSP hidden danger. Some friends bought a hard-drop machine with a period of time after the frequent crash is this reason. Therefore, Roger here also recommend that you buy soft drop machine, so as not to cause quality problems in the future. (So far, we have the concept of soft and hard down)
The above 3.10 and 3.03 is just an example, now have been cracked to realize the soft down.
Cracking the concept of cycle lag
So, with this knowledge in hand, Roger will analyze the current market for you. The market will cyclically alternate between the following three phases.
Phase 1: SONY releases a new system
Since the new system is not yet cracked, hard drop machines start to be released in large numbers. At this time merchants started to stock up on the soft drop machines on the market, and the hard drop machines would be slightly cheaper than the soft drop machines.
Phase 2: SONY's latest system is cracked
Since the systems of the newly released machines are uncracked, the machines with cracked systems are discontinued again. At this stage the market will be slowly digested with soft drop machines, and one day it will be digested. At this time the market is full of hard downgrade machines, soft downgrade a machine is hard to find. The price difference is huge.
The third stage: SONY's current latest system is cracked
This time the hard drop machine has no meaning, all the machines across the board price drop.
In fact, the third stage of the situation: the latest system is cracked, the updated official system has not yet come out of this period, almost very short. SONY in order to combat piracy, non-stop will come out of the new system to suppress. Therefore, most of the time is in the state of the latest system is cracked. We call this phenomenon crack cycle lag.
The concept of the boot disk
Then in the state of the latest system cracking out this problem. Didn't we talk about SONY requiring all new machines to be bundled with the latest system in order to combat piracy? Now SONY also requires that not only machines, but also all games and software that have not yet been released must be on the latest system (not cracked) in order to work properly. Won't all these new games be unplayable if the latest system is in a cracked state? What to do? Hackers have come up with a way to make these new games work on a special system by using a UMD disk of the original game. This is why genuine game UMD disks are often called boot disks. Note that it must be a genuine game disk to boot, a genuine movie disk will not work. And not 100% of all games can be perfectly bootable, after all, it's a pirated version lol.
Magic Battery's new brushing method
All of the brushing methods described above were before August 2007, and should be considered obsolete today (don't throw eggs, to become an expert, you must understand why). In August 2007, hackers breached SONY's internal specialized repair battery. With this battery, it was possible to downgrade or upgrade to any desired version (both official and special) under any version (both official and special) at will. This battery is called the Magic Battery. Therefore, after August 2007, with the Magic Battery, there is no longer any need to downgrade and then upgrade, and you can do it in one step.
System blueprint changes
In September 2007, Sony launched the PSP2000 console, which was bundled with the official 3.60 system, now upgraded to 3.71. It was this 3.71 system that, like 1.5 when it was cracked, became the new generation of special system blueprints. At the same time, the previous PSP1000 console system has stopped development until 3.52, and will no longer be released as an official upgrade. Currently all PSP special system (including 1000 and 2000) all through the magic battery for one-step brush, and all brush to 3.71 as the blueprint for the special system to run cracked ISO. the role of the boot disk is still valid to continue to this day. (I searched the internet and read this article before I bought my PSP)
The above is my own experience, I hope it can help you.
