Function vtlb_MapHandler

pcsx2/vtlb.cpp:735–748

Maps the given hander (created with vtlb_RegisterHandler) to the specified memory region. New mappings always assume priority over previous mappings, so place "generic" mappings for large areas of memory first, and then specialize specific small regions of memory afterward. A single handler can be mapped to many different regions by using multiple calls to this function. The memory region start a
