If set, Sound Blaster ports alias by not decoding the LSB of the I/O port.

This option only applies when sbtype is set to sb1 or sb2 (not SBPro or SB16).

This is a hack for the Electromotive Force 'Internal Damage' demo which apparently relies on this behavior for Sound Blaster output and should be enabled for accuracy in emulation.
