PlayStation makes them far more difficult to emulate, even for the original manufacturers. The most technically advanced consoles that can currently be successfully emulated for commercial games on PC are the PlayStation 2 using PCSX2, and the Nintendo Wii U using the Cemu emulator. A PlayStation 3 emulator named RPCS3 is in development, although it can currently only run small Homebrew games and certain old arcade titles that were originally ported to the PS3 from older platforms. Most emulation software mimics a particular hardware architecture, often to an extremely high degree of accuracy. This is particularly the case with classic home computers such as the Commodore 64, whose software often depends on highly sophisticated low-level programming tricks invented by game programmers and the demoscene. Other projects aim to bring compatibility of older games and its features back to modern platforms such as WineVDM (for running 16-bit games on 64-bit Windows), nGlide (for enabling Glide (API) to other video cards), IPXWrapper (for enabling IPX/SPX based LAN play). Controversy PC games have long been a source of controversy, largely due to the depictions of violence that has become commonly associated with video games in general, with much of the criticism stemming from the fact that the PC gaming industry isn't as regulated as on other platforms. The debate surrounds the influence of objectionable content on the social development of minors, with organizations such as the American Psychological Association concluding that video game violence increases children's aggression, a concern that prompted a further investigation by the Centers for Disease Control in September 2006. Industry groups have responded by noting the responsibility of parents in governing their children's activities, while attempts in the United States to control the sale of objectionable games have generally been found unconstitutional. Video game addiction is another cultural aspect of gaming to draw criticism as it can have a negative influence on health and on social relations. The problem of addiction and its health risks seems to have grown with the rise of massively multiplayer online role playing games (MMORPGs). Alongside the social and health problems associated with computer game addiction have grown similar worries about the effect of computer games on education. Computer games museums There are several computer games museums around the world. In 2011 one opened in Berlin, a computer game museum that documents computer games from the 1970s until today.
