byuu says: I added (imperfect) memory conflict timing to the SA1. Before: - WRAM↔↔ROM ran 7% too fast - ROM↔↔ROM ran 100% too fast - WRAM↔↔IRAM ran 7% too fast - ROM↔↔IRAM ran 7% too fast - IRAM↔↔IRAM ran 287% too fast - BWRAM↔↔BWRAM ran 100% too fast - HDMA ROM↔↔ROM ran 15% too fast - HDMA WRAM↔↔ROM ran 15% too fast - DMA ROM↔↔ROM ran 100% too fast After: - ROM↔↔ROM runs 14% too fast - HDMA WRAM↔↔ROM runs 7% too fast - DMA ROM↔↔ROM runs 4% too fast If you enable this with the fast PPU + DSP, your framerate in SA1 games will drop by 51%. And even if you disable it, you'll still lose 9% speed in SA1 games, and 2% speed in non-SA1 games, because of changes needed to make this support possible. By default, I'm leaving this off. Compile with `-DACCURATE_SA1` (or uncomment the line in sfc/sfc.hpp) if you want to try it out. This'll almost certainly cause some SA1 regressions, so I guess we'll tackle those as they arise. |
