I wonder how quickness determines the region - there's nothing in the Core Options (like Nestopia or Fceumm) which can select the Region. How is the ROM file named ?

@edmaul69 Yes, Thanks, I disabled it. But I also have sound problem with fceumm, and quicknes is recommended for achievements, so I'll continue to search why my PAL ROMs play awful :)

@edmaul69 said in NES emulators in 16:9 black bars discussion: @backstander it doesnt work in fceumm because it became a core option. And core options override retroarch.cfg files. in theory core options and retroarch.cfg options shouldn't really overlap. core options are those that are specific to the core you're using (enable_multitap or whatever), whereas retroarch options are potentially applicable to all libreto cores (enable_shader), although in retropie we have separate retroarch.cfg files for each core, as well as an /all/retroarch.cfg for generic options. so in my opinion, overscan options should either be a retroarch, or a core option, not both, but i don't really know the intention/history of that option.
