Hello i'm Mrnuage, some years ago I managed to get the third place on Castlevania 3 Sypha JP route.

Long story short, until now, I only had a laptop. At the time it was good enough to stream an NES emulator. But then for some overheating reasons, I couldn't have decent performances.

Now I got a new PC and I can stream again but there's still some details I don't know. At the time, I used Nestopia to achieve this time. Now I wanted to check again what are the authorized emulator for speedrun and found that FCEUX was authorized. I tested it but I wasn't satisfied because either I disable V-Sync and there are some stuttering, or I enable it but the sound crackles and I can't fix this.

So I quickly googled what is the most accurate NES emulator and found it is Mesen. I didn't know this one until now but after some tweaks, I've got what I want. The speed is perfect and there's no stuttering. So now my question, is it an authorized emulator since it's pretty accurate?
