There are several cores for a system to be emulated, such as for NES, the fceumm-, quicknes- and nestopia-core. But do we need for the n3ds so many cores for a system? Is there not a core which is the best? Especially for nes and snes?
What about Picodrive and Genesis-plus-gx ?
Thanks in advance.
Okay basically this is what I have found out so far, this is from my own personal experience.
I personally use Nestopia It works with no problems or when there is its easy enough to tweak and fix. I have heard FCEumm is good as well. I like Nestopia as I have it on my PC and I think the Nes DS emulator was a Nestopia build. and never had any problems.
Anyway you really only need one core for each system you want to emulate, some emulators only emulate certain games or hardware addons for that system. see below
Best Cores for best systems using latest build of Stable Retroarch (1.5) are as follows.
Pictodrive: Best systems emulated as follows, MegaDrive (60Fps) Mega CD (60Fps) and 32X (45-60 Fps game dependant)
No SG-100 emulation and Mastersystem has graphical Issues mainly vertical tearing form what i've witnessed still runs at 60fps.
Genesis Plus GX: Best systems emulated as follows, SG-100 (60fps), MasterSystem (60fps with FM sound), and Gamegear (60Fps).
Does also emulate Megadrive 60Fps (MD suffers from vertical tearing issues)and Mega CD at 35-40 FPS (60fps with mute)
Nestopia: Nes and Famicom Disk System games (60Fps) (even supports Konami's special VRC6 chip for enhanced sound in Castlevania III)
Snes9x2002: Slower than 2005 but some games have better compatibility.
Snes9x2005: overall best speeds do far but some games not working. Try in 2002 core
Mednafen Neo Geo Pocket: NeoGeo Pocket Colour Good speeds mostly 50-60 fps however some games run quite slow & choppy at around 45 fps.
Side note: 1:1 aspect ratio crashes certain games in retroarch under
Mednafen Neo Geo Pocket. Personal Favoured Aspect ratio is 16:15 haven't had any problems as of yet and near enough to 1:1
Edit: 1:1 ratio (maybe fixed since [retroarch 1.5] update) as after testing today seems to work fine without crashing.
Ultimately for the best Snes speeds and emulation including Special Fx chip games Use Snes9x_3ds standalone emulator installed as a Cia
