Thanks for the prompt reply guys. I did install rev20 and rev21 as base56 (on both 249 and 250) but didn't work. I tried installing the cIOSX rev21 d2x v3 but when the download starts, the installation is interrupted with the following error: "HASH BAD", so I installed via ModMii / MMM (249 on base ios 56 and 250 on base ios 57). Updated CFGLoader to the latest version (68d). Also didn't work. Froze at the same place. Argh! I am playing the undub version btw.
