| Unmapped write only EE memory (confirmed only for SIF) || Reads/Writes to 0x2000000+ shouldn't throw bus error on dma transfers. Write should be performed as successful, memory should stay unchanged. Reads should return 0. || Games developed by In Utero, while creating initial save file, send DMA where address is EE stack pointer. At the time of transfer start $sp is too high, and requested transfer size make MADR overflow above 0x2000000 at some point. This is game bug, and happen also on real hardware. Fixed by config. | | Unmapped write only EE memory (confirmed only for SIF) || Reads/Writes to 0x2000000+ shouldn't throw bus error on dma transfers.
