Wolf 3D levels (trying to convert Mac Levels to IIgs)

[Anonymous <x.y@tennis.net>]

Can anyone help me out with this?  I have a PC to download with.

I have tried a few times to convert some levels, but Erics' Level 
converter tells me the files I am trying to convert are not Macintosh 
scenarios.

My problem is unpacking the .HQX files, I think.   

Should my PC be able to unpack these files correctly?  I have unpacked 
them on my PC, and it does not give any error messages.  These files will 
not work with the converter program though.

I tried to unpack the .HQX files on my IIgs, first using GScii+, but then 
GShrikit shows the file as SHADOWED, and you cannot select it to unpack 
it.
