UPDATE!!!!!!!1111ONE
If you are reading this, keep in mind that this thread was made before the GTA eloader was developed. I fully intend on creating a new thread for helping people decide whether or not to update to even higher firmwares based on the capabilities of this eLoader. For now, I want those with GTA to know that the eLoader offers an interesting new homebrew launching method that is smoother compared to the previous TIFF exploit on 2.0. It works on firmware 2.0 and all current higher firmwares (through 2.6) and has the same compatibility list as the tiff exploit, to my knowledge. If you're considering updating to 2.0 or higher, look into it.
If you're a fan of homebrew and have remained at firmware 1.5 despite the features of 2.0, you're no doubt familiar with the restrictions that accompany this lifestyle. As a homebrew psp gamer, you often find yourself jealous of mainstream psp gamers, reluctant to purchase newer and better games for fear that they may require a forced update (after all, most of us got into homebrew because of the poor quality of games at launch), and unable to receive the features included in the newest firmware updates, such as the web browser and AVC support. As a homebrew gamer, at times you feel special, able to bridge the generation gap with parents and teachers by showing off old-school emulators; yet at other times you feel left out, stuck in the past. After all, you have forsaken the ability to play newer titles in order to play emulators and independent software that Sony doesnt even want you to play in the first place. It is true what Sony representatives say; "It's not what the system was meant for." We were never meant to have this choice, but since we do, it's made owning a PSP far more complicated than it ever should have been.
Luckily, however, our good friend Fanjita has uncomplicated things a bit. His 2.0 eboot loader has opened up new doors for the homebrew community, allowing us to blur the line a bit between homebrew and mainstream psp gaming, at least until Sony starts forcing 2.01 and higher updates on newer games. With the release of the highly anticipated "Grand Theft Auto: Liberty City Stories," many homebrew gamers have come to the point in their journey where they must make a choice. Well, don't fret gamers, because I am here to help you with that choice.
Is 2.0 really for you?
Before making the jump to 2.0, I encourage you to examine the differences between the two frmwares. In addition to helping you decide whether or not to upgrade from 2.0 to 1.5, I hope that this part of the guide may also help those considering downgrading from 1.5 to 2.0. The 2.0 System Update has many advantages over 1.5, and features you may find to your liking. However, by updating to 2.0 you may lose many of the freedoms you enjoyed on 1.5 concerning homebrew software. By comparing the capabilities of the two versions and balancing the advantages and disadvantages of each, I hope to help you, the homebrew gamer, come to a conclusion about which Firmware is best for you!
1.5
Pros
Intuitive Interface - Because of the way the 1.5 hack works, homebrew software runs as easily as if it were a downloadable game demo. It was Sony's original intention to allow interactive games to be downloaded to the memory stick in the form of pbp files called eboots. However, because they have taken so long to follow through with this and polish their execution, it made it easy for homebrew developers to create their own eboots. These eboots run from the games section of the PSP crossbar, in the highlighted white memory stick icon, not to be confused with the clear white memory stick icon (save files) and the UMD icon (UMD games). Once highlighted, many homebrew applications have cool looking animated menu appearances, much like when highlighting a UMD. Homebrew apps boot up with the PSP logo, much like UMD games.
Full Access to In-Game System Features - While playing homebrew programs on 1.5, you can still use the Home button and stand-by features, just like in a UMD. These features are currently unavailable in 2.0 and are very convenient. The home button allows you to see what time it is at any point in gameplay, as well as allow you to return to the psp menu without performing a hard reboot. This allows you to easily go from playing homebrew to listening to music, watching videos, or even playing a umd, and return to playing homebrew just as easily. In addition, the standby feature allows you to put your psp to sleep at any point during gameplay, and revive it hours later at exactly the same spot you left off. This can come in handy in rpgs where you arent near a save point, and it saves more battery than you would simply putting it on hold. However, sometimes the PSP will freeze in emulators if you attempt to standby mid-rom. This doesnt always happen, but its a good idea to exit to the emulator menu before going on standby, as you can easily return to the game from there once you revive the unit.
Full Homebrew Library - With the way homebrew functions on 1.5, the psp gives the application all the utilities it would to an official sony eboot or UMD. This means that any homebrew that comes out for the PSP will work on 1.5, including applications that require kernel acess such as UMD Emulators, ISO loaders, Wifi or IR applications, and others. If you intend on illegally downloading PSP games without purchasing them and playing them on your PSP, or if you just want to have full acess to any homebrew released, you will want 1.5. (Note: If you intend on using your PSP for piracy of UMD games, please do not seek assistance with the fine people at PSPUpdates, as it is against their policy. If I am correct, they do not supply UMD Emulators or Iso Loaders.)
Cons
Limited UMD Library - In response to the Piracy aspect of the homebrew community, Sony retaliated by adding forced updates to all of their newer games (and as far as I know, movies). This means that if you remain at 1.5, you can only play earlier released UMDs, such as launch titles and a few after. However, through piracy options such as UMD Emulators, you may still be able to run newer games by downloading them illegally off the internet. (Note: Once again, we at PSPUpdates do not condone of this kind of behavior.) Regardless of this ability, with the release of GTA:LCS, it has become evident that soon even this may be phased out, as it may be possible for Sony to prevent newer games from being emulated on lower firmwares.
Lack of Web Browser - Though you can still get on the internet using homebrew alternatives such as the Tenchi No Mon Browser, it is at times buggy, slow, and unresponsive. In addition, you have to find it elsewhere, as it is technically piracy.
Lack of AVC Support - 1.5 still has the ability to play mp4 video, but once you've seen AVC quality, you can never go back.
Battery Guzzler - For some reason on 1.5, if there is ever a UMD in the tray, regardless of whether or not you're playing it, it still spins. This means that whenever you're listening to music, playing homebrew, or watching mp4 videos, you're also wasting battery life unecessarily. However, you can solve this by simply removing the UMD.
2.0
Pros
Browser - The king of 2.0 features, the 2.0 web browser allows you to easily navigate pages with the convenience of javascript support and Sony's seal of approval. Though it doesnt have flash support, you can easily navigate the QJ Forums, use web-messaging programs such as e-messenger.net, and download directly to your memory stick.
Custom Background Support - If your girlfriend nags that you spend more time looking at your psp screen than looking at her, slap a digital photo of her on your memory stick and set it as your background! :) Seriously, the custom background feature is fairly neat, and though it isnt a true necessity, it is part of what allows 2.0 homebrew t function...
AVC Support - If you intend on staying at 1.5, never have a friend show you the quality of AVC in comparison to regular mp4. AVC quality video rivals that of a UMD movie, and is a must if you intend on converting your movies yourself rather than wasting money on UMD movie releases when you already own the DVD.
Atrac3 - In addition to the video format AVC, the 2.0 firmware also supports a better audio format, ATRAC3Plus, which has an excellent compression rate.
Battery Conservation - I'm not sure if anyone else has noticed this, but if you pop in a UMD on 2.0 and listen carefully to the device, you can hear it spinning, preparing to load the game/movie. However, if you choose to go play homebrew or listen to music, the UMD slowly stops spinning. I have also noticed that while playing emulators I have significantly longer battery life, even with the UMD in. This means that you can take full advantage of the lower battery requirements of playing music, movies, or homebrew from the memory stick, even WITH a UMD in the tray.
Full UMD Library - For now... currently there are no UMD games or movies forcing updates higher than 2.0, but for now this means that you can play any PSP game released without worrying about losing homebrew.
Cons
Unintuitive Interface - On 2.0, eboots cannot be launched from the game portion of the psp crossbar. Instead, they must be launched within the Eboot Loader, a folder within your photo folder. Usually the eboot loader launches without a hitch, but on occasion, depending on the situation, this will cause your psp to freeze. This simply means that you have to perform a hard reboot and try again. From here on, however, the newest eboot loader's GUI (graphical user interface) is very attractive and fairly easy to use, though you do have to press X... too many times, once to select a homebrew, once again to load the eboot, and once again to REALLY load it.
Lack of In Game System Features - Because of the way the eboot loader works, we dont have as many tools to use on 2.0 as we did on 1.5. This means that in 2.0 we no longer have acess to the home button or the standby feature. However, with the release of eboot loader 08, you can restart your psp simply by pressing start in the eboot loader menu, or by holding L, R, and Start for a second within any homebrew program.
Limited Homebrew Library - Without Kernel Acess, Wifi, or IR capabilities, the list of working homebrew on 2.0 is limited, and though it is growing every day, most new homebrew programs dont always work on 2.0. Most of the more popular emulators are up and running, but as for popular homebrew apps such as the internet radio app and others, you may be out of luck.
Despite 2.0's disadvantages, its many features and the ability to play newer UMD games often make up for them. In addition, the possibilities of 2.0 homebrew are growing every day. In conclusion:
If you play homebrew and nothing else, 1.5 is for you.
If you play mainly emulators, 2.0 is for you.
If you play mainly independent homebrew games, 1.5 is for you.
If you play illegally downloaded PSP games, 1.5 is for you.
If 1.5 is for you and you are currently using a 2.0 psp, be warned that downgrading can damage your psp.
If 1.5 is for you and you are currently using a 1.5 psp, remain at 1.5.
However, if 2.0 is for you, then...
Welcome to the exciting world of 2.0 Homebrew!
Congratulations! You're ready to make the jump from 1.5 to 2.0! Though 2.0 homebrew is still in its infancy, the list of working homebrew is growing every day, with the help of Fanjita (the creator of the 2.0 eboot loader) and the 2.0 homebrew community. You'll find that though 2.0 has its limitations, the boundaries are constantly being pushed, and when balanced with the great features of 2.0, these restrictions are easily forgotten.
Like many of you I had to make the inevitable jump from 1.5 to 2.0 when I purchased Grand Theft Auto: Liberty City stories, and though that may not have been your reason, chances are that if you're reading this thread, something has pushed you to update. Its true, the world of 2.0 homebrew is very different than it was on 1.5, and updating can be a stressful experience, but I hope to get you through it in a quick, easy, and convenient fashion. Trust me, you won't want to go back. :)
Getting Started
Your first step along the path of 2.0 homebrew is, obviously, updating your system's firmware. You can do this by either downloading the 2.0 update here: All Update EBOOTs and FAQ (24 June 2008)
Or simply by updating to 2.0 from a UMD, such as GTA: Liberty City Stories.
Q: But Jay, everyone says that the UMD update is somehow special, and cannot be downgraded!
A: Nope! Its just regular 2.0, and if you decide you ever want to return to 1.5, its as easy as a MPH downgrade.
The fact of the matter is, updating from the UMD can be very convenient, especially if you have a 56k connection. The update file may take an hour or two to donwload from the internet, and you'd be better off simply updating from the disk.
No matter what you do, however, DO NOT USE THE NETWORK UPDATE FEATURE IN YOUR PSP! This will update to the newest firmware, 2.5, which has fixed the bug that allows 2.0 homebrew. If you do this, you can never downgrade.
Now, if you updated to play a game such as GTA:LCS, I suggest you spend your first hour or two with the 2.0 firmware playing the game. If you love it, you know you're here to stay. However, if you dont think it was worth the update, then you may want to reconsider downgrading. Just remember, if you want to be able to play newer games, you're going to need 2.0... at least until a higher update is forced.
The next step is downloading the newest version of the Eboot Loader by Fanjita. You can grab it here: http://fanjita.org/psp.html
Once you have done this, check the faq on how to install it here: 2.0 Eboot Loader Guide and FAQ (This faq contains a lot of useful information on 2.0 homebrew.)
Now its time to try it out! For the 2.0 eboot loader, you will only need one eboot for each homebrew application, as opposed to the 1.5 method, which requires two. Many times when downloading a homebrew program from www.pspupdates.com, the download will contain two versions, a 1.0 and a 1.5. The 1.0 version is a single eboot, and can be used with the 2.0 eboot loader. However, if you wish to simply use some of your existing 1.5 homebrew without re-downloading them all, simply use the larger folder out of the two, as this contains the main eboot. This folder still goes where it would on 1.5, in the game folder.
Tip: Since you are no longer booting homebrew from the game menu on your psp, feel free to rename the folder something more easily recognized. For example, my NesterJ folder is labeled Nintendo so I can easily recognize it as the Nintendo Emulator. This will make the Eboots show up as corrupt from the game menu, however, and if this really bothers you, rename the folders to something like NES 1. This is a short capitilized name, under four letters, followed by thirty spaces, and a one. This will make it so that the eboot doesnt show up under game at all. It is, however, still there, and can be launched within the eboot loader.
Getting to know the Eboot Loader
Now that you have the 2.0 eboot loader, familiarize yourself with the way it works. Unfortunately you can no longer use the home button to check the time or exit from homebrew, but with Fanjita's newest version, you can restart your PSP as easily as pressing L and R, plus start, and holding them for a full second. In addition, you can no longer use the standby feature, however you do have a few options.
By creating a state save within the game, you can easily return to your exact spot later on. Just because you have state saved doesnt mean you have to stop using regular saves however, as they will still be recognized after you continue a state save.
If you only want to put your psp in your pocket for a few minutes, simply slide the power button to hold, making sure the yellow circle is visible. In the SNESX emulator, however, you may want to exit to the menu first, however, because the hold button oddly does not affect the thumbstick, and it may slide around in your pocket, altering frameskip settings and whatnot.
If you dont know how long your psp will be in your pocket before you can play again, depending on the situation, you may want to turn off the screen and mute the sound before putting it on hold. This should reduce the amount of battery wasted at least by a little bit.
You'll find that occasionally the eboot loader may freeze up when you try and start it. This can be frustrating from time to time, but usually its a result of not having a clean reboot. Simply reboot your psp by holding the power down for ten seconds, then turning it back on. You get used to this.
Despite these differences, if you're a fan of emulators you'll find that it pays off to be able to go from stomping goombas in Super Mario Brothers to running over mafia goons in GTA with ease.
Next, familiarize yourself with the working homebrew. Not all homebrew releases work on 2.0 currently. This is because many homebrew applications utilize a feature called "kernel acess." Don't worry yourself too much about what it is, just know that it requires functions within the PSP that cannot be acessed via the 2.0 exploit as of now. This means any homebrew application that uses kernel cannot operate within the eboot loader. Before you launch an eboot, the loader checks for any instances of kernel acess within its programming. If it finds any, it will tell you, and ask you if you want to go ahead and try to launch it. Some homebrew, such as PSPGenesis, may suggest kernel acess, but still work on 2.0. However, if the program cannot work within the loader, it will tell you so. Usually you can skip checking if the eboot works yourself by looking over at the working homebrew list here: *Official* PSP 2.00 Working Homebrew Discussion
In addition, if there is an application not on the list and you have checked whether or not it works, please share your findings on the thread mentioned above.
Tip: I am currently using PSPGenesis version 1.18c, Rin version 1.32, NesterJ version 1.07, and Y's newest SNES. Most of these are emulators I was using on 1.5. For emulators that do not work, such as the newest GBA, try using these other emulators to fill the void. You'd be surprised how many GBA games are simply rehashings of other games on currently emulated systems!
Currently, one of the main issues with the 2.0 homebrew community is the lack of concern for the limitations of the firmware. As of now, we're still working with eboots designed with kernel acess in mind, and as it seems kernel acess can be avoided, I look forward to seeing more 2.0-friendly releases in the future. Because of this, the future of 2.0 is looking brighter and brighter every day.
Getting to know the 2.0 Firmware
At first, you may find the restrictions of 2.0 homebrew dissapointing in comparison to the freedom of 1.5. Once you get the hang of it, however, the new features of 2.0 combined with the capabilities of the 2.0 eboot loader can ultimately increase your PSP's overall value as a universal media device.
The Browser, for instance, is one of 2.0's most prized new features. If you are never near a wireless access point, this feature can seem meaningless, but let me be the first to tell you that you can find wifi in some of the most unlikely places. For example, I was sitting in Church before a service, goofing around in my network connections, not expecting to connect. I did, however, proving that there is a wifi acess point SOMEWHERE in my church! :) The keyboard is much more intuitive than it was on the Tenchi Browser, and pages load faster than they ever did on it either. With the addition of javascript capabilities, the 2.0 browser allows you to navigate the internet nearly as easily as you would from a computer!
In addition, you'll find that the quality of AVC is FAR superior to that of 1.5's standard mp4. Never again will the action be skewed by tiling and blurring. If you dont intend on purchasing UMD videos, but rather ripping and converting your own, you'd be stupid not to update. To obscure the dvd's original quality by forsaking AVC for standard mp4 is a crime. With AVC you can watch movies in their full glory, without having to buy a UMD of a movie you already own.
(I would seriously appreciate it if someone gave me some links to sites for DVD to AVC conversion methods. I would link you to PSPVideo9, but it seems like I'm the only one that finds this program to be the poorest peice of crap I've ever seen. If you message me with some links I'll be sure to post them here)
Despite the limitations of 2.0 homebrew, some of 2.0's features actually HELP it rather than hinder it. For example, you may have noticed on 1.5 that if you ever have a UMD in the tray, despite whether or not you're playing it, the motor still spins. This wastes valuable battery life, no matter whether you're watching an AVC, listening to MP3s, or just playing homebrew. The only way to solve this problem used to be taking out the UMD, but if you're like me, being able to carry a UMD within the PSP itself saves space in your pockets.
On 2.0 however, the motor slows to a stop if you arent actually playing the game in the UMD tray. If you don't beleive me, put your ear to your psp after putting in a game, then launch the eboot loader. You can hear the whirring of the motor slowly die down. This greatly increases battery life, especially when playing homebrew without overclocking. To get the most out of playing emulators, for example, systems such as the NES and Gameboy Color run at full speed on 222. This means playing Super Mario Bros 3 on Nes as opposed to playing the All Stars version on SNES saves much more battery life, meaning you can play longer. This is one of 2.0's greatest features when it comes to homebrew, and in my opinion makes up for the eboot loader's limitations.
2.0 Also has increased image support, allowing you to view bmps, gifs, and pngs on your psp, meaning you dont have to resave images as jpegs just to show them off. In addition, you can send them to other 2.0 users via wifi. In addition, you can now create your own custom backgrounds by simply setting an image as your wallpaper. Technically you HAVE to have a custom background to use the 2.0 Eboot loader, so find yourself a good one!
Closing Statements
There you have it! Hopefully if I have done my job, your transition from 1.5 to 2.0 will go smoothly. Please enjoy the new features you have gained, and if you are new to the forums, be considerate to the long time members by searching for answers before asking a question that may have been asked before. If I have made any mistakes in this guide, please tell me and I will fix them post haste. I want everyone to get as much help out of it as possible, and I dont want anyone receiving the wrong information.

). Something like 95% of known LUA scripts run perfectly on 2.0.
