Thanks a lot chutia and foleyjo for your help.
I have just 3 games, Bandicoot PS1, all 3 roms are USA (america) so as bios i installed the USA bios "SCPH1001.BIN"
Except for not beeing able to save the game where i want everything else with this bios work fine, all games run smoody, everything perfect, no problem about sound too, all with the default setting, i did not change any setting, all are by default.
Thje only setting that i change I just hide onscreen controls cause i have the ps3 gamepad, about this subject i found a bug anyway this has nothing to do with this sobject, for the rest everything is fine except for save game, i'm not able to save them where i want.
I download bios "SCPH1001.BIN" from internet i did not rip by my self, i dont know even how to that, what does it mean rip bios? I extract from iso the bin file of the 3 above mentioned games, i did it by my self and that is all.
