All 2D systems had sprite limits, SNES Megadrive/Genesis included, its just how the hardware worked, and most emulators for those systems have options to turn off sprite limits. The pixels are 10:11, just like the Wii, so we don’t even need to tweak the video encoding. While Nestopia holds up reasonably well for its age, these days there are emulators with higher accuracy and a friendlier interface, like. Nestopia is also available as Libretro core (for RetroArch).

Another developer has continued work on it since, as 'Nestopia UE' (Undead Edition). Personally i use the Retroarch core though. Genesis Plus GX, Nestopia, and Gambatte all run at full speed from my tests, no frame drops or audio stuttering occurred in my testing. The original developer halted development of Nestopia in 2008. MESEN has been the best and recommended go to NES emulator for some years now, i have used it for probably 3-4 years myself. This is in Pixelmusement's video so I highly suggest watching it all the way through, it's totally worth it. To reduce slow-down go to Options>Emulation>Overclocking>set Additional Scanlines before NMI to 400. To do so you'd go to Options>Video>Advanced>Remove Sprite Limit (checkmark it) - this will reduce or eliminate the flickering of objects, uncheck the "Automatically re-enable sprite limit" option.

The next awesome part is that you can change the sprite limit to keep the gameplay smooth, reduce flickering, and prevent slow-down. okay so I know how to overclock but I am not sure how to change/use the fceumm Libretro/Retroarch core instead of the Nestopia core. What I took away from that video is that the Mesen emulator is incredibly accurate as it actually emulates the visual glitches and slow-downs that the actual hardware produces. I highly suggest you watch it as it's incredibly informative as to how the NES works. What an amazing video with the explanation about sprites and the drawing limitation per scanline.
