Google молчит о данных программах для MSX, куда уж мне

Даже самый продвинутый эмулятор openMSX, ничего не знает о Пистолетах со световым лучом

не, как раз о пистолетах там все верно !)
на msx все работает с:

Cosmic Sheriff
Solo
Target Plus
Duck Hunt
Mike Gunner
Dungeon Hunter (ASCII Plus-X Terminator Laser)

а так , да, тот софт для спека...

The light pen works just like an on-screen touchpad, and applications should be interchangeable between it and the MSX-Touchpad. The only subtle differences that applications developers should take into account are:

While the light pen works over the real screen, the touchpad is a "blind" device. Thus, the light pen will not require any kind of "mouse pointer" , while the touchpad will require one.
The light pen is designed to force the user to click the button to get a reading, while on the touchpad the user get a reading simply by touching the pad and the button can be pressed independently. On the light pen, to click the button without touching the screen the user must literally do that: click the light pen outside of the CRT glass area.
_____
There are two standards for the light pen interface. The MSX BIOS abstracts the differences in their hardware.
User software programmers *must* read the touchpad only by using the BIOS GTPAD call as described in the beginning of the article. The low-level implementation details listed bellow are explained just to provide information for hardware designers, emulator programmers and the programmers of the C-BIOS. В сети есть лучшее качество ниже приведенной фотки.

cherkasy, ясно... То есть пр наличии соответствующего по, мы можем припаять к msx, имеющему должный интерфейс, и пистоль от денди, и перо от ес7927
