Sony quickly patched the firmware again, continuing the cat-and-mouse game with the hackers and users. Dark_Alex had released a Custom Firmware called "Dark Alex's Open Edition firmware" or "Custom Firmware (CFW)" which opens the firmware and allows users to use the existing feature set of the current edition. One of the drawbacks of downgrading the PSP is that new official media may require the presence of a new firmware edition. Dark AleX, as well as other variations of the name, is a pseudonym under which he worked. Dark_AleX Two PSP-1002s running on 5.50 GEN-B.ĭark AleX (aka Dark_AleX, Dax) was a Serbian programmer who wrote homebrew applications for the PlayStation Portable. This reportedly caused more buzz in the community than any recent official offerings for the device. In mid-2006, after several months of problems in defeating the PSP's firmware a file was posted online which allowed new PSPs running firmware version 2.6 to downgrade to 1.5 so they could then be hacked using older methods. Over the course of 2005 Sony released six different versions of the firmware and hackers typically responded to it by downgrading to avoid the new security updates. Users attempting to downgrade their PSP using this software instead found that it was rendered inoperable as this software deleted mandatory/important system files. Symantec called this trojan "Trojan.PSPBrick". Hackers and other homebrew enthusiasts then encountered the first trojan for the PSP. In August 2005 Sony released version 2.0 of the firmware which included the web browser, file compatibility updates and other features. BusinessWeek dubbed this the "carrot-and-stick" approach. Hackers refused to apply updates which would render their hacks unusable so Sony attempted to convince users that there was a benefit to upgrading by including new features in the firmware updates, such as a web browser, and not just security patches to plug the vulnerabilities. On 15 June 2005 the hackers distributed the cracked code of the PSP on the internet. Sony released version 1.51 of the PSP firmware in May 2005 to plug the holes that hackers were using to gain access to the device. Soon after the PSP was released, hackers began to discover exploits in the PSP that could be used to run unsigned code on the device. Several demoscene non-interactive creations were released targeting PSP such as Suicide Barbie, purely to demonstrate optimisation skills of the developers and the power of the handheld. This effort led to development of Toolchain and SDK by enthusiasts and paved the way to utilise vector floating point co-processor, GPU and audio capabilities of the device without asking Sony for permission. The reverse engineering process to understand the PSP hardware started shortly after the advent of homebrew unsigned code execution. PlayStation 1 emulation was native, made by Sony. Numerous different emulators were created for the most popular consoles. Homebrew emulators were created for NES, SNES, Game Boy Color, Game Boy Advance, Sega Genesis and Nintendo 64 console systems among others.
