Sorry to hijack this thread but I recently bought "Eye of Judgment Legends" and "Metal Gear Solid: Peacewalker" on UMD and I've upgraded to 5.50 GEN-D Prometheus but I can't run those games as it needs me to upgrade to official 6.20 FW and I don't want to do that.
Is there any way I can play UMD games that are 6.00 and above on CFW without upgrading to official FW
