Hello. I have problem with DMA. When I want to run one of game which supports DMA (for example f355 challange, sonic adv2) my console gets for a few second black screen, and reset itself. Everything works correctly when I unchecking DMA option. My Dreamcast had of course IDE mod and boot_loader_unlock_G1_IGR_dbs.bios. I have no idea what wrong with this DMA....

Regards

What image type? If GDI, it's optimized or not?
You use true async DMA or emulating async? Show settings screenshot.
