You can get Pkunzip here,
but it's a little tricky. Geocities doesn't allow me to have files ending in .exe, and pkunzip is called pkunzip.exe, so this presents a problem. Fortunately, for those of you who are desperate, or have no idea about this stuff, I am intelligent.
You can get Pkunzip here, but hold on!!!!!!!
It is not a zip file, but it is stored on the server like that so I am allowed to hold it here. When you save it, instead of the name 'pkunzip.zip' save it as 'pkunzip.exe'. You need not do any more than that!
