Hi, Mednafen developer.
Can you add "Dendy-mode" to Mednafen please?
Most of modern desktop NES emulators already support it, as well as official NTSC and PAL timings.
"Dendy-mode" is name for pirate PAL timing that allows running NTSC games at 50 FPS while maintaining compatibility with them, unlike official PAL NES.
Here is complete information about timings:
Cycle Reference Chart - nesdev wiki
Table of differences
Global Nesdev F.A.Q.
Dendy mode have specific behavior, so here are region test roms:
Toggle Spoiler
240pee by Tepples (Damian Yerrick) must show timing:
note: cycles/line and cpu speed will show a bit lower values on Mednafen NES core, due it sprite evaluation inaccuracy.
Overclock test
How it must look in all 3 modes:
note: cycles/line and cpu speed will show a bit lower values on Mednafen NES core, due it sprite evaluation inaccuracy.
Battletoads and Double Dragon (U).nes
Must have glitches like this:
"Choujin Sentai - Jetman (J)" intro glitch:
Noise and DMC APU pitch tables are same as NTSC NES/Famicom,
so Sunsoft NTSC games must have correct pitch
