@Darksavior nes accuracy is measured through various tools to verify correct ppu/cpu/apu operation and proper support with the most popular nes mappers, support for obscure mappers isn't accounted during those tests tbh.
Mesen probably had missing/broken support for that mapper 078 used in 2 games (Holy Diver and Uchuusen - Cosmo Carrier) at the time of its release.
Afaik Mesen is the only emulator getting 100% at those tests, nestopia is around 80%, quicknes is around 70%, fceumm is only around 50% and the least accurate nes emulator available on retropie.
I don't know if there is any nes emulator with 100% mapper compatibility, there are several hundreds of them and they all need to be coded separately.
How do you enable Use Local Art? I have my videos named "romname.mp4" so I will rename them to "romname-video.mp4"
Open the Emulationstation menu with Start and try looking through the available options - I think it's in the UI sub-menu (?).
Also, so that is what that little pop up box is for, not sure how I missed that in the Docs. What does this part mean: "(the bottom face button is recommended as to not accidentally change anything) " ?
@vol-2 Oi, Phantasy Star is one game where the FM sound definitely was not better (IMHO). The author of the FM version didn't properly truncate notes and the bass line is nearly inaudible. FM sound is decent many other games, but not Phantasy Star.
@grant2258 Thank you for the response! I certainly can use the standalone version, which I will probably end up doing. I want to eventually (possibly) replace my Raspberry Pi with a small laptop that runs RetroPie, since I have access to better hardware. So I was hoping to setup a system I can connect to the TV and use the interface entirely with the controller.
I'll just have to make due for now, and choose a solution that suits me best.
