I have a Dell OptiPlex 390MT, and I have the PS3 XMB WALLPAPER, the 2009/2013 slim OS startup sound, but I would also like to have the startup beep. IDK if i could code it using some method on the bios, but I do have another motherboard that i could practice flashing to do so. I also want to eventually get a working ps3 XMB Menu that is compatible with a wireless PS4 controller(or a wired Power A PS3 controller specifically), and using all of the original PS3 icons. I want to eventually build a pc in a PS3 slim case, which is why I want to figure out all of the software side stuff first. I already know its possible with those size constraints plus or minus a few modifications.
