Okay... I'm new to all of this, but here's my situation. I upgraded from 1.52 to 2.00. I downloaded the 1.50 EBOOT as well as the MPHDowngrader. I used the MPHDowngrader successfully, then went on to do the 1.50 update. That was converted successfully, but for somereason everytime I try to play any game it tells me I can't untill I update to 2.00 and there is a 2.00 update icon under the game menu, but not on the memory stick. Can someone please help me or point me to a link that can.

What games are you trying to use?

-edit from what you are telling me, each UMD Game you put has a 2.00 Upgrade icon. That means that each game you want to play requires the firmware 2.00

Some games with 2.00 Firmware upgra can be used without the necessary upgrade, however some have differently encoded files and as of right now this cannot be bypassed.

Try the SXT Version Changer v2.02, it will not work with some games like Socom, GTA, and King Kong.
