MSX Joystick are atari-compatible. Only 1 trigger will be available, as 2nd one is an MSX variant.
Atari mouse protocol is different from MSX. Look at the bottom of this page:

Really strange
I think it will not work for MSX, as pin 5 is +5 V, pin 9 is GND and pin 8 is "strobe" for MSX mouse protocol. Maybe it will work as a joystick or do random responses...
