Really that happens because the fifo.CPReadWriteDistance is negative. Example: CPReadWriteDistance: -864 CPEnd: 10092672 fifo.CPBase: 9568416 In SMG this is because PI_FIFO_RESET is writing and after fifo.CPReadWriteDistance will be setted to 0. To Prevent that, I've Implemented AbortFrame function in the CommmandProcessor. It should fix overflown because of that. Note: There is other issue (Issue 2846) where the fifo.CPReadWriteDistance is negative too but the effect is different. I'm working to solve this. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6083 8ced0084-cf51-0410-be5f-012b33b47a6e
