Paradise Arcade Shop has new technology for the 2014 year.
PAS developed a still unnamed add-on to the Sanwa Denshi JLF lever where players can program aspects of the lever including sensitivity, size of cardinals directions and diagonals and more. All of the programming can be modified through its dedicated USB port.
As an easy-to-install plugin to the JLF, it replaces the normal gate found on the JLF and players can also remove the stock JLF switches. It will require both a normal JLF harness as well as an additional 5v harness to properly power the accessory.
Still in development phase, the unnamed JLF add-on will be available sometime this year. You can check out screenshots in the link above.
