For Yaba, enable "Low Latency Mode". | | Game crashes after Stage 3 | Corrupt ISO. Re-download from Redump, verify CRC32. | | Slowdown (emulated, not original) | Original Saturn hardware had slowdowns with 10+ sprites. To remove it, overclock the virtual SH-2 CPU to 200% (Beetle Saturn → Options → SH2 Overclock). But purists leave it at 100%. |
