with an AO rating for its violence and the explicit sexual activity in the "Hot Coffee" minigame. At the time, Yee had been promoting the AB450 bill, which would require the state of California to place warning labels on violent video games and require retailers to check for identification before selling these games to customers. On the following day, while Vance criticised Yee for his "crusade ... to undermine the integrity of the ESRB", she also announced that the Board had opened an investigation into "the circumstances surrounding the 'Hot Coffee' modification". On 12 July, meanwhile, the Australian Office of Film and Literature Classification (OFLC) announced that it was opening its own investigation into the game at the request of Philip Ruddock, the Attorney-General of Australia. The OFLC had originally rated San Andreas MA15+, which limited purchase to individuals aged 15 or older. While "Hot Coffee" had been popular among the Grand Theft Auto modding community upon its release, Yee's comments drew the public's attention to the minigame. In a statement on his personal website, Wildenborg clarified that although he was not responsible for the creation of any explicit sexual material present in the game, such material was impossible to access without modifying the source code, and thus "Hot Coffee" could "therefore not be considered a cheat, Easter egg or hidden feature but is most probably just leftover material from a gameplay idea that didn't make the final release". On 14 July, Rockstar Games released a statement denouncing any responsibility for "Hot Coffee", stating that the minigame was "the work of a determined group of hackers who have gone to significant trouble to alter scenes in the official version of the game". On 20 July 2005, the ESRB announced that all editions of San Andreas would be re-rated from M to AO. While acknowledging that Rockstar Games had not intended to make any graphic material accessible to customers, they issued the re-rating on the basis that the material was present "in a fully rendered, unmodified form on the final discs" of the game, which, "compounded by the broad distribution of the third party modification", undermined "the credibility and utility of the initial ESRB rating". As a result, major retailers such as Walmart, Target, Best Buy, and Circuit City announced that they would immediately cease all sales of San Andreas for as long as it was rated AO. On 29 July,
