Since you all are here using this patcher i take it none of you are playing online as this WILL get you banned.
Now thats out of the way, once you have the latest firmware for your dvd drive there is NO need to wave patch ANY iso as the firmware is waveless and will boot the game regardless.
Getting the latest firmware is highly recommended, the latest firmware will still play your old burns.
If you are playing offline there is no need to buy an iHas burner, you can just truncate the burn with imgburn. You burn as you always has done, imgburn will then tell you the file is too big do you wish to truncate? Yes you do. Verbatim DVD+R DL are the only recommended discs for burning so if you have any problems burning with something else thats your own problem.
Again, wave patching and truncating WILL GET YOU BANNED, please update your firmware.
You can also inject topology data to enable XGD3 games to be played on LT2.0 but thats just an annoyance and i wont post it. Goolge is your friend their.
