Hello, I am using A570 1.01a I already copied PS.fir, DISKBOOT.bin and the CHDK folder into the root folder of my 2gb SD card. I tried to get to alt mode but I couldn't. Nothing pops up when I click the direct print button. Can anyone tell me what's wrong? Do I need to be in playback mode or shooting mode to do that? I tried both, but couldn't get the alt function to go. And I heard we can add games into the camera, how do we do that? Thank you in advance
