Most of the hacks now use pretty common games like Lego Star Wars or Lego Batman that are not going for £100 on ebay. You can probably find them in the bargain bin or something. It's not THAT hard to find these games unlike previous hacks that used games that were out of print, and thus very expensive to procure.
Just be glad you don't have to buy some really shitty game like Hannah Montana. At least if you buy Lego Star Wars or Lego Batman, its actually a game worth playing.
And really? Is £12 too much money for you? You can get Lego Batman on Amazon UK New for that much. STILL too much. You can get a pre-owned version from GAME for £10. Save up your damn lunch money for a week and you can afford it. Don't expect us to pity you for being such a cheap bastard. You want to pirate games, is £10 really a deal breaker? Before you had to buy a mod chip for that much then pay someone to install it. Today you buy a game, follow some instructions and bam you're all set. WHAT MORE DO YOU WANT? Mana from heaven? Do you want us to send hookers to your house? A few kilos of cocaine?
