This is the most important section. While emulation is legal, downloading files from public websites often enters a grey (or black) legal area.
There is virtually zero performance loss. Modern processors are so fast that they can decompress CHD or CSO data on-the-fly in milliseconds, faster than the emulator simulates the PS2 disc drive.
