Joy 2B+

joy2b

This small modification is to adapt two or three buttons to a joystick for ATARI 2600/XL/XE.

Some advantages of this project :

  • More than 40 games are available and growing in the future
  • Only the joystick needs to be modified by adding a resistor for each button added
  • Compatible with some SEGA gamepad to use two buttons
  • For developers it can be emulated from Altirra by configuring a custom joystick
  • Modifications of some commercial joysticks are also available
  • A test program is provided for proper testing of all buttons

Hardware changes

The technical details to proceed to perform the modification are documented here

Testing program

Thank you Eyvind Bernhardsen for your improvements to the test program.
