0.6.2 / 28-03-2019



BlastEm aims for cycle accuracy while also hitting lower system requirements than similar emulators. It has substantially higher compatibility than Exodus but falls short of Genesis Plus GX. Commercial game compatibility is close to, but not quite at, 100%. It is the only emulator other than Exodus that can properly display direct color DMA demos and to pass all of the tests in Nemesis' VDP FIFO Testing ROM.
