I was trying to import some of the fan games to make it a little easier to extract information like game versions, etc. Most of them crashed WinAGI without warning on import, even though I was using 2.3.5 installed after uninstallation of the old version. Without a debugger it is hard to track down where it might be failing.
One thing that seems to work is to copy a stub WAG file with nothing more than the [General] section with no values except the the interpreter version added. This works to view logics and pictures, but none of the other resources. This may be enough for my current purposes, but it would be nice to be able to explore all of the resources.
