Code for the Nightfallcrew vhdl version is already posted, or have a look in the pdf "PLA Dissected", it's all listed.
You'll find the VHDL code in the link already provided:

Copy the part under "CÓDIGO: Bitte melde dich an, um diesen Link zu sehen."
Then just compile, set the pinout properly and you have your jed-file.
You'll have a pretty compatible version when done, if you don't want to spend 4-5 hours doing this (maybe 24 hours downloading software from Xilinx as the server is quite slow) then I suggest you just buy a U17 PLAnkton or maybe a RealPLA, that works a lot better than this almost ten year old non-refined "Nightfallcrew version", IMHO it's worth the money - or simply buy an XC9536 from eBay and you can use the already available file.
