Method GetTerminator

pcsx2/SIO/Memcard/MemoryCardProtocol.cpp:199–206

This one is a bit unusual. Old and new versions of MCMAN seem to handle this differently. Some commands may check [4] for the terminator. Others may check [3]. Typically, older MCMAN revisions will exclusively check [4], and newer revisions will check both [3] and [4] for different values. In all cases, they expect to see a valid terminator value. Also worth noting old revisions of MCMAN will not

// Also worth noting old revisions of MCMAN will not set anything other than 0x55 for the terminator,
// while newer revisions will set the terminator to another value (most commonly 0x5a).
