| DMA between SPR and VU1 memory cause emulator panic. || Currently cause is unknown. It seems that functions responsible for transfer don't check that VU is running. Manual state that dma can be performed only when VU is not active, and pcsx2 wait until VU end. Games affected in emulators on ps3 display this warning in pcsx2 if mtvu is enabled: "MTVU: SPR Accessing VU1 Memory". Affected games are fixed by rearranging code to do lq/sq loop instead of DMA. || Summoner 2 (SPRfrom to VU1 data mem), Kaena (SPRto from VU1 data mem). | | DMA between SPR and VU1 memory cause emulator panic. || Currently cause is unknown.

| IOP SIF0/1 DMA IRQs can be disabled (masked), which is not true on real hardware. || IOP interrupts 0x2A and 0x2B should always trigger. Fixed by patches to IOP code. Ps2_emu seems to be unfacted, probably handled on real hw in CXD9208GP | | IOP SIF0/1 DMA IRQs can be disabled (masked), which is not true on real hardware. || IOP interrupts 0x2A and 0x2B should always trigger.
