PC can't read the PS2 file system. You need your PS2 to be capable of running homebrew, and then you need the latest version of uLaunchELF running on your PS2 to copy those files to a USB flash drive. Macro and map marker files are the few files that are identical between the PS2 and PC versions.
You can also use that to delete temporary files, if it can be figured out which ones are causing the problem, so the patch will work.
All you need to run uLaunchELF on an FFXI-compatible PS2 is for someone to set up FreeMCBoot on a memory card for you with an already modified system, as the system will boot the exploit from that memory card without modification. PSX-Scene has plenty of people offering to do it if you mail them a memory card to set up for you.
