The Nintendo 64 has always been a difficult machine to emulate correctly. But in 2025 - we should be well and truly past all of it right? Not exactly. Issues with Plugins, performance, graphical glitches, stutters. Unless you have a very powerful machine, these are common things many of us will run into when emulating the Nintendo 64. But why? And Is there any hope for fast, accurate N64 emulation in 2025 and beyond?
The core if it boils down to, when emulating older machines, is the consoles processor speaks language A, and our computers all speak language B
The emulator has to translate back and forth between A<->B faster than the speed the original processors would’ve just spoken A
So translating A<->B is a way tougher task than just reciting A. So you need a tremendously better CPU than what the console had to emulate it.
It’s kinda like, Dropping a rock in a pile of sand is easy. Simulating dropping that rock into the pile of sand in real time accurately is really challenging.
Not only that. Emulators must often ”cheat” to achieve high speeds. This means emulators doesn’t try to achieve a 1:1 replication of what’s happening inside the hardware, but something that’s gives close enough results and better tailored for modern hardware.
The reason why N64 is particularly difficult is because each game must be optimized individually (due to the heavy reliance on microcode). The emulator must replicate the hardware at a much lower level for an accurate emulation of all games. Emulator developers can apply optimizations on each individual game, but it’s incredibly time consuming to do so for every game in the N64 library.
