Vdp1 : The core uses arbitrary lines to draw the quads.The interpolation algorithm for line drawing needs to be fixed, there is pixel drop-out at the moment. Ought to be embedded into some other emulator (example: Genesis) and tested thoroughly. Is not as robust as it would need to be to run any sort of arbitrary code, but is enough to run the standard Sega sound engine that numerous Saturn titles use. M68k : Instruction level timing, messy and needs refactoring. I don't know how the fm works, so it is unemulated. The timing is emulated near the cycle-level, although this is not necessary. Scsp : Needs all floating point math removed. We need more test programs for the actual hardware to make sure the instruction set is correctly emulated. Lots of 7604 on-chip functionality is buggy or unimplemented. Sh2 : Instruction level timing, instruction set should be fairly accurate. Commercial games do not work yet as far as I know. gui_sdl insert_your_cd_filename_here.bin to run the sdl versionĪble to run some homebrew demos. Go to platform\build\cmake and type cmake CMakeLists.txt SaturnKi is an open source Sega Saturn emulator.
