I have been playing around with that, don't think that ever amounted to anything. After reading it all nobody confirmed launching an elf with the method. I was able to create the APA partition and view its contents. I also was able to inject an elf file into the IMAGE.DAT but have no way of launching it because i don't have the FFXI Original discs.
I have also been launching ps2 backups from disc using swap trick. I can also load elf files using the swap trick method but that was easy & not what i am trying to accomplish. Launching directly from XMB is what im looking for.
