Ive fixed definitely Pokemon XD in dual core mode. This game is doing something not allowed. It attach to CPU the same fifo attached to the GPU in multibuffer mode. I added a check to prevent overwrite the GPU FIFO with the CPU FIFO. If the game do that on breakpoint the solution can fail.

Fixed ReadWriteDistance calc when CPRead > CPWrite.
Added Token and Finish cause to GP Jit checking.
