Im not sure what your main goal is..
but i spent months trying to portabilize MagicDisc.
It's not possible because it utilizes a low-level driver "mcdbus".
But that's the hard way..
There's no need to portabilize MagicDisc, as there are working Portable ISO software available
I use these 2 software for all my ISO needs:PassMark OSFMountPortable WinCDEmu
As for your Gizmo.. im not sure what that is.. i don't use it.
but to find out whether a software writes to the registry, i use RegShot.RegShot Portable
: it takes a before and after snapshot of the registry and even drives if you specify. What i love about it over other similar software: is it's extremely fast! You will have to get used to reading the output log, but after a few usage, you'll start to see a pattern and understand how to decipher
If i can figure it out, anyone can!
