Running a program with such opcodes would result in a program exception on modern systems. This option scans the program code segment at startup and replaces all detected privileged operations with NOP (no operation) instructions. Since these opcodes are often dedicated to interactions with sound hardware, the program will likely work with the possible side effect of some audio issues. Use this flag for games like Ubik.</span></p>
