Created DS1204 device & switched megatouch to use it instead of it's own local version (driver could do with some more tidying up as not all games use a key but currently it is hooked up to all games). Default data comes from a region instead of coded in driver, commands & security match are now compared, data is clocked on the correct edge, key can be written to and is saved to nvram. [smf]
