I'm trying to simulte an SD card in ISIS but I don't seem to be getting any where
I created an card image ust using notepad (not sure if this is the correct way) but all that happens is, It asks me to insert card so I click to close card then it just says opening file and sits there and does nothing else.
I found a 32mb image file from here tried that and it just reports file exists.
What is the best way to create a card image file. It works in real life but I really want to use ISIS (been lazy and easier
)
