if the imgburn version you are trying to use has issues, then try using an older version or use disk juggler.
imgburn needs the pftoc files to add diskjuggler support.
if you are having issues with any of the pso cdi files, make your own selfboot version from the raw gdi files and create an .nrg iso
then use nero to burn the .nrg
or buy a gdemu and use a gdi file from sd.
or buy a sd card adapter and play pso v1 only.
or play pso for pc instead
maybe your gd rom laser is slowly dying?
soon it will not boot any disk..retail or cd-r!
use flash eraser disk to clear dc memory.
use the serial from your retail pso disk if you have it.
if the serial is ver2 it should say so on the sticker that came with the retail pso disk.
if you want use a shared serial instead.
basically you can't have a unique guild card on server if you use shared serial.
easy way to tell what version of pso you have is: orange text for character name is v2, white text for character name is v1.
35 AE FF FF is v2
FF FF FF FF is v1
connect to sylverant server or connect to another server or host your own server.
there are different servers, you're not stuck with choosing only one.
at least there used to be... some1 will chime in soon?
if you want to host a server there is software available.
host a dns server or use dreampi master dns or use patch disk or use auto connect disk or use codebreaker codes.
there are probably a few things i am leaving out..but, you have many options.
idk maybe this helps?
