Currently, the following instructions are translated: - CACHE (indexed) - CACHE (va based): translated to a SYNCI, overkill on D-CACHE operations, but still much faster than a trap. - mfc0/mtc0: the virtual COP0 registers for the guest are implemented as 2-D array. [COP#][SEL] and this is mapped into the guest kernel address space @ VA 0x0. mfc0/mtc0 operations are transformed to load/stores.
