Yes, I found the Wombat3 VGA kml+bmp. It's good, but not the fantastic "looks like the real calculator" interface I'm hoping for.
On my other (QVGA) device, I've been using PPC horizontal, which looks similar to a real 48, but buttons are moved around. I'll start using Wombat2 so I can be consistent between PPC's.
I'm using 1.06... wasn't released very long ago. :approve:
