A couple of months ago I posted that UMD’s (Universal Media Disc that games are supplied on for the PSP) had been cracked. Two months down the line not only can all UMD ISO’s be downloaded from the net – they can now be played from a memory stick – PSP Warez is alive and kicking. The hacks that allow this only work on firmware 1.50. Sony has released two firmware patched since 1.50 but they are not compulsory so if you want to play warez, home-brew software and emulated games on the PSP stick to version 1.5. Some games will not play unless the firmware is at the latest version. What’s the betting that GTA:Liberty City Stories will be one of them? But then again – who’ll buy the original if they can download it from the internet and play it for free from a memory stick.
