First your sound issue is more than likely hardware, fixing it can be a bitch, but if you want to try Complete PSP Disassembly. Secondly your pandora is probably just losing its charge I recommend just buying another fat battery and using it as your main battery (you can of course keep the pandora for recovery and modding). Third you don't get too much upgrading your firmware but I recommend updating to 5.00m33-6 and then installing the latest promethus mod which will allow you to play new games with on-the-fly encryption (http://www.pspmod.com/forums/psp-beg...-one-link.html. For your last question, converting ISOs to CSOs is not advisable because compression hurts file performance meaning it may not work right, I suggest using UMDGen to open the ISO and rip out the crap, check my sig if you're interested (http://www.pspmod.com/forums/softwar...33-manual.html).
