All of the Kodak drivers have a simulation mode that allows you to test their devices. Download the drivers for the Kodak i100, i200 or i600 (or whatever device you’re interested in).
then go into %windir%twain_32kodak
you’ll see a ‘a shortcut to const.ini’ and a ‘a shortcut to ramscan.txt’
From the ramscan.txt, you can see what sim modes that device supports, and you just modify the const.ini to reflect the sim you want,
so if I want to simulate a duplex device, I could download and install the i100 driver, and in const.ini set Simulate=i160 (the i160 has duplex support the i150 doesn’t)
I’ve got the i100, i200 & i600 installed along with the video DataSource from http://www.dosadi.com/beta_products.htm and of course the sample Source that came with the twain toolkit, and I rarely have to connect to a ‘live’ device to do debugging or testing.
If you come across more device simulators, post them.
