Alright I'm back again since I haven't yet resorted to getting an NDSA+ just yet. Again used the latest update & the program just hangs up as before after pressing B. Also marc_max's slot-2 tool failed with some kind of "FAT file" error - I can't remember exactly what it said but I'll try again later & post it. Still using Datel's Max Media Dock & patched with the mmcf.dldi file. Details on the product can be found at us.codejunkies.com
EDIT: OK the error I got was after it identifies the cart as HG & comes up with some values, then prompts to press A to start the backup. It then gives me the error message "Initializing FAT... Failed!" & prompts to turn of the DS lite. Anything I can do to help figure out what's happening short of donating the actual hardware? It seems like everyone else is able to get slot-2 methods working except with the Max Media Dock. I'm too cheap at the moment to give up on it yet & invest in another slot-2/3-in-1 device.
