General questions
Which core is the best to emulate (some console / game) ?
There is no best core, each has a different use case (accuracy, speed...).
I can't load / the core crashes on startup with (some game)
Why does some core / game run slowly ?
It is likely because your system is too slow.
I saved in game but it didn't work / RetroArch crashed and I lost my save
RetroArch doesn't save in real time, SRAM is saved when you hit "close content".
In some cases it's possible that closing RetroArch without closing the core first loses the saves
from the current session (especially on Windows).
To fix this you can enable the "SaveRAM autosave interval" option under Settings > Saving.
Be aware that it might corrupt your save if you close RetroArch while the game is saving,
especially in games that heavily use the SRAM and with a low autosave interval.
Another option is to use save states.
If you're on Android, make sure your save folder isn't located on an external SD card,
it won't work.
Why is (some core) running too fast ?
It's likely because you have VSync and / or audio disabled.
Platform-specific
Linux
I can't download/update cores because the online/core updater is missing
Windows
When I try to load a core on RetroArch it says "No Core"
RetroArch crashes on startup
Your GPU or OS might lack OpenGL 2.0 support. To get around this, you can try changing the video driver by going to your RetroArch folder -> retroarch.cfg and change "video_driver" to either "d3d9" or "gdi". If that setting is not already there, you can add it.
I can't see (some core) in the download list
Maybe you have accidentally downloaded the Windows XP build, which is not compatible with all cores.
