This means the system is not powerfull enough to emulate the game/system at full speed. Given it's a Pi3, it's not unusual since N64 emulation is not fullspeed on it.
Yes, that's correct and this is how the image works. There are no games included with the image and you need to add your own games to it in order to play games.
and try to fix it but I really going to do anything. if you do know how to fix this please comment. but i don't feel like going on a emulator website and downloading all the game.
@mitu seems like I may have to settle for a middle ground then. Yes it is an interlaced image. I hate that There is no way to independently control the resolution on emulation station. Thank you for all of your assistance.
I may continue to tinker with adjusting the resolution.
