Hi,
I've traced the IKBD rout I've included in my previous message.
I've put traces for all components and I get strange result.
I've moved the mouse very slowly not to have >127 or <128 values on both X and Y axes.
I've done the trace under hatari and I have no joystick configured and I don't press any key.
As you can see, I get some unwanted "ghost" keyboard or "joystick" packets.
Any idea where they come from ?
For the "multi packets" if a X value is >127, I think the ACIA sends sequences like this : $F8,$7f,$0, $f8,$5,$0 ... So this shouldn't be a problem (I'll verify this).
B00f8 IKBD_Main
0001 IKBD_Mouse_X
0000 IKBD_Mouse_Y
00f8 IKBD_Main
0001 IKBD_Mouse_X
0000 IKBD_Mouse_Y

00f8 IKBD_Main
0001 IKBD_Mouse_X
0000 IKBD_Mouse_Y
Another try (I've moved the mouse quickly on the left / right).
Here, the "IKBD_Keyboard" value is higher ($3e) (and it looks like a mouse_X value)
It looks as if in the second mouse detection, the $f8 of the next mouse command is into the mouse_y one and everything is moved by one byte.
It seems OK again after the 2 wrong keyboard commands.
Any idea ?
