If the games are running well I'd say no .
it can do better than that, theres a turbo core which boosts FPS on games that struggled. Theres two games that are not fully playable or have some issues, Conkers bad fur day and something else which escapes me, playable but with issues. Its a really impressive core - i use it at 240p/120hz on my diamontron monitor and it looks glorious.Impressive if it can do n64 at full speed.
yes it works fine. You might have to remap controls in the core if you havent done it before. I use the N64 switch controller with mine and it works a treat. (xbox and 8bit do controllers also work fine for me)I tried Mario 64 with my usual 8bit do pad and couldn't run forward for some reason. Anyone else tried it yet?
