Just got a PAL xbox and would like to make it region free and capable of outputting progressive scan with PAL and NTSC games. Is there a chip that will direct boot both PAL and NTSC games in progressive on a PAL machine or is it necssary to get a US machine? Can such a chip be disabled - some US gamers have been locked out of Xbox Live when connecting with chipped machines? I would also like to run Mame - is it difficult for the non-technical gamer? How does PAL progressive compare to NTSC when the PAL game is set to 60hz? Is the PAL60 signal better than NTSC when in progressive mode?
