TL;DR: No difference between BizHawk and Fusion.
Hi, everyone. After reading discussions on Sega emulators accuracy for speedruns, including praises for BizHawk and criticisms on Fusion, I decided to make my own tests on different emulators, by recording and doing frame counts.
I used a segment of about 1m25s, that goes from the moment Riki starts leaving the room, after beating Wang from the left side, until the next title screen rolls once and cuts to black. Here are the results I got.
- Fusion 3.64: 5120 frames (1m 25s 333ms)
- BizHawk 2.8 (SMSHawk): 5120 frames (1m 25s 333ms)
- RetroArch (Genesis Plus GX): 5101 frames (1m 25s 017ms)
- BlastEm: 5128 frames (1m 25s 467ms)
This is just an informative post, so people know that, while emulators may differ from each other, I don't see Fusion as an issue for Black Belt, especially when compared to BizHawk.
I was able to record on my SMS console and frame count exactly like you did.
- SMS console: 5127 (1m 25s 450ms)
7 frames slower than Fusion & BizHawk
