Can anyone send me a true way to convert a SEGA phaser or an NRES Light
gun to work on my ATARI 7800?
thanks

Yup.

The 26/52/7800 FAQ tells how to do it through internal modifications
to the SMS gun. A few weeks ago, I posted this simple external
adapter that requires no modifications to any hardware. Only needs
9-pin male and female connectors and a 7404 inverter.
