Please add an emulation of Inkwell Systems lightpens. The code description is:

/* Inkwell Pen */
{ GUN, 0x04, 0x20, 20, 0 }

It emulates both the one-button 170-C and the two-button 184-C models.

    do you have a testcase for this?

    Added in rev 27371.

    Test case would be geos, since it has an input driver for this kind of lightpen.

    Test program and drivers for lightpen emulation

    I have attached a test program and drivers for the C64 and the C128. They are similar to the test programs for the mouse emulation. The two PRG files are self-contained; the drivers are linked into them. When you run the programs, calibrate the drivers by clicking on the vertical line near the center of the screen. Then, click off the white bar. The program will show where the pen is pointing; and, which buttons are being pressed.

    Those programs can be used to debug the NTSC mode bug (its lightpen Y co-ordinate is 12 too high).

    You may add them to the testprogs library.
