In the command processor when FIFO_READ_POINTER is reading Is better return fifo.CPWritePointer instead fifo.CPReadPointer.

Browse source 
In this way it prevents wrong fifo.CPReadWriteDistance in the future. That should fix RE0 Issue 2846 and others "Warning: GFX FIFO: Unknown Opcode (0x4d)" in dual core mode.
