I have added it already. Can you use CVS version of ARAnyM?

I have added the 0x0f, 0x10 IKBD opcodes emulation to ARAnyM but I don't
see how that could help if linux-m68k sets the upper left screen as the
mouse origin (I am trying to avoid the "top"/"bottom" words as they are
implemented differently in the IKBD than in my head).

Anyway, just give it a try, please, and let me know.

You can attach any PS/2 mouse and keyboard to Atari.

It just adds new scancodes - I have provided a link to the scan codes
table in one of my previous mails.

The middle mouse button is mapped to scancode 0x37 (IIRC) while the
mouse wheels are provided in IKBD status packet.

Or check this:

search for SDL_BUTTON_MIDDLE and SDL_BUTTON_WHEELUP/WHEELDOWN.
