Okay, so I'm trying to get CHDK to work with my PS a3300IS. I've got the files on the SD card, and I'm all ready to start using CHDK. Except that there is no "firmware update" option on my camera. I'm starting into playback mode, I've tried it with and without the SD card in, and I simply can't find it. I checked that the PS.FI2 file is there, so that shouldn't be the problem. My firmware version is 1.00D, if that helps. Any suggestions?
