I’ve been getting a lot of complaints about my last article from the 10 Days of Hacking due to the sudden decrease of quality, and I want to apologize by creating a bonus day where I want to talk about some interesting hacks and developments.
Consider this the real Day 6 if you may.

ARK eCFW was released 1 month ago and has been the eCFW of choice for many of you. Sadly, updates are sparse and lots of questions remain unanswered. People contact us regularly about ARK with questions that actually have simple answers. Here is a quick reminder of what ARK can do for you. Below is the FAQ from Coldbird’s blog. Important reminder: ARK is currently not available for Vita OFW 2.05

Team PRO recently published an updated version of their CFW for the PSP. The new version is named PRO – C2 and basically solves some problems with the NoDRM engine. The changes are fairly “old” (if you have the guts to grab the nightly builds or compile by yourself, you might have had these changes on your PSP since December), but the binaries were published only a few weeks ago.

With the release of ARK, we have been seeing more and more questions which basically tell us that many users are having trouble using other menus in ARK. Today I will explain why TN-C menus will not work as is in ARK and I will also answer some questions that I am seeing all too often. Read the rest of this entry »

One of the biggest questions that users have surrounding ARK is compatibility with PSX games. In this post I’ll explain why psx doesn’t work natively on the vita, and how ARK managed to make it work.

ARKThe PRO team (the people behind the PRO Custom Firmware, probably the most popular piece of software of the PSP scene these days) are back with a huge release: a PSP CFW for the Vita, running on the recently revealed UNO exploit. Codename: ARK

If you’ve been using the UNO exploit, ARK is basically an alternative to Total_Noob’s CEF. At the core, ARK is a port of Pro CFW to the PS Vita, and seems to bring features that might be lacking in CEF. In particular, the Readme emphasizes the following:


  • PSX game support (soundless so far, our sound plugin is too glitchy for public use at the moment)
  • ISO/CSO game support
  • NoDRM Engine for decrypted dlc playback
  • MS-SpeedBoost (most noticable on games like soul calibur)
  • Stargate Game Patches (fixes several anti-cfw games)
  • Customizable Main Menu
  • Plugin support
  • Recovery support
  • ISO-cache support (speed up ISO gaming)

Some of you might remember a leak of some of Coldbird’s work a few months ago, which led him to leave the scene. ARK is the project that was leaked back then (although the leak was encrypted, and therefore not usable), and that the Pro team decided to release today. I assume the decision was taken a while ago, but porting the existing work to the new firmware 2.02 might have taken some time.

Although I haven’t tried this specific build, I was lucky enough to try early builds of the ARK project a few months ago, and overall I was impressed. Coldbird left the scene while he was in the middle of bringing sound support to PS1 games, so it is unclear if the sound plugin for PS1 will ever see the light of day, but independently of that, I am pretty sure ARK brings a nice new option to those of you looking for alternatives to CEF.

Credits for the ARK project are the following (from the readme):

  • Dark_Alex for the initial M33 CFW who guided us mentally through several CFW generations by giving good examples on how to patch Sony OFW.
  • VirtuousFlame: For the ISO Loading Code, Custom PSX EBOOT Support, PSPCipher and most of the CFW related code.
  • Coldbird: For Proshell, and all his CFW related code & Vita redesign of PROCFW.
  • Yosh: For the initial sceWlanGetEtherAddr leaked kxploit, yMenu, other kxploit related things and various pieces of code.
  • thecobra & frostegater: For precisions about this kxploit.
  • neur0n for his syscall execution in kernel mode, several bug fixes and other CFW related code.
  • ardi for his umd4homebrew to enable UMD in homebrews.
  • Zer01ne for the initial Uno exploit discovery.
  • All our testers.
  • And last but not least – Sony for making wonderful, however very locked down, portable gaming handhelds.

Download, install & use

You can download the files here. You’ll notice that one of the download links is “ad sponsored” (linkbucks). We offer alternate links, but the revenue from these ads go to the Pro team and help fund things such as the server for Prometheus online. Alternatively, the pro team has a donation link for those who want to show their support.

In order to install, just unzip the savedata matching your region to your CMA folder, and install the savedata using CMA, like you would install any other PSP savedata to your vita (more details in the readme). If you’re on Windows, we recommend to use OpenCMA when you copy files to and from your vita.

To run ARK, once you’ve installed the Savedata to your Vita, just run UNO, and press “X” when asked to do so by the game, this should load the eCFW menu.

Coldbird’s FTP for Vita is also a recommended tool to install once you’re all set, to make copying backups and homebrews easier.

As I said, I haven’t tested this build yet, so give the files a try, and post your comments here. In particular, I’m sure we’d all like to know how it compares to CEF :)

Important note: This release requires that you are running on a PS Vita with firmware 2.02 or lower. It also requires you to have a legit copy of the PSP game UNO installed on your Vita. UNO has been removed from the PSN by Sony a few days ago, so if you missed the exploit announcement and don’t have the game on your Vita, you’re out of luck, this release will not help you in that case.

We mentioned it earlier today: Frostegater, the dev we’ve been hearing a lot from lately has recently joined the PRO Team, a team that have great developers such as Virtuous Flame, neur0n and Yosh/wth (sadly, coldbird left, we miss you bro).

There has been news of a new exploit potentially being released soon. I am seeing a lot of enthusiasm from this, and that is to be expected. However, I will let it be known right now that those of you waiting up all night tonight refreshing these pages that there will be NO RELEASE TONIGHT. Heck, there may not be one for a couple days. If this release indeed DOES happen it will go through what is called a ninja release.

Update: Urbanix was now removed from the stores, so don’t try to get the offer. Check our latest blog entries to know what you should do next.

A few days ago a CFW was leaked, involving (among other things) a usermode exploit in the game Urbanix. You might remember that Urbanix was given away for free a few months ago, and people who were paying attention at the time could see there was a good reason we were excited about that free offer from Sony. It turns out the offer is still valid, you can still get Urbanix for Free on the PSN in Europe as long as you have a facebook account and a EU PSN account.

Due to DNS problems with the old domain, we were forced to move things around a bit.
The Prometheus CFW / Online Server Main Page can now be found on !
The Community Forums are now available via !

I’m sorry for any inconveniences caused.

Greetings, Coldbird ~

If you own a PSP and follow this blog, it is likely that you installed the latest Pro CFW on your console, and you might be enjoying the new online functionality that was added recently by Coldbird. (For those who don’t know what I’m talking about, the latest Pro CFW allows you to play online with games that would only allow adhoc mode otherwise. For details on this feature and the free service provided by Coldbird, check this article.).

Sadly, the central server for this service is currently down for a lot of users.
