I have come to the point where I run WodeFlow, and pass the iso mount by auto-loading CFG.
The fun stops there though, as the screen freezes at a "Please wait" screen and eventually pops up a "Wode not found" message.
I don't really know what more info you want me to provide, as I'm pretty much blank on these things.
I do, however, use system 4.1, and I'm perfectly able to boot my iso files from the disk manually.
If you want more details, feel free to ask : P
