extern long physw_status[2];
static long kbd_new_state[3];
   sprintf(osd_buf, "1:       %8x  --> %8x", kbd_new_state[0]);
   draw_txt_string(20, 10, osd_buf, conf.osd_color);

   sprintf(osd_buf, "2:       %8x  --> %8x", kbd_new_state[1]);
   draw_txt_string(20, 11, osd_buf, conf.osd_color);
   sprintf(osd_buf, "2:       %8x  --> %8x", kbd_new_state[2]);
   draw_txt_string(20, 12, osd_buf, conf.osd_color);

Is the address of _platformsub_kbd_fetch_data  correct ?

I see the S90 build uses _GetKbdState, no idea why.

In the A2000 code, it says  :-

   // The following three lines replace the call to kbd_fetch_data
   kbd_new_state[0] = physw_status[0];
   kbd_new_state[1] = physw_status[1];
   kbd_new_state[2] = physw_status[2];

Replace _platform_sub_kbd_fetch_data()  with :-

   kbd_new_state[0] = physw_status[0]; // <---- Add this
   kbd_new_state[1] = physw_status[1]; // <---- Add this
   kbd_new_state[2] = physw_status[2]; // <---- Add this

That is slightly different to the version that you said does not work.


EDIT

Are you using _platform_sub_kbd_fetch_data()  or _GetKbdState()  ?
