I have a copy of Gary's work before his webpage went down. Yes it can be 
fairly easily ported to any Xilinx FPGA if you want the basic ROMs internal 
to the FPGA. External ROMS would require some modification if you 
wanted to go into a smaller FPGA. 

Currently his work needs to be in an FPGA with at least 21 block rams in a 
Spartan 3 series. Far less if the Coco ROMs are removed to external
