UltraHLE 2064 is an old emulator that came out of an even older emulator. While it has a decent number of users today, the question you have to ask yourself is whether or not it is worth the trouble when you have so many modern alternatives to choose from.
What is UltraHLE 2064?
UltraHLE 2064 is a descendant of UltraHLE, an N64 emulator that RealityMan and Epsilon created. When UltraHLE came out in 1999, it was hailed as a revolutionary invention that advanced emulation technology significantly. The emulator was a marvel because it came out just three years after the N64 was released and yet, it could run commercial games at a decent frame rate.
Unlike earlier emulators that wanted to replicate the low-level operations of specific consoles, UltraHLE used the ultra-high-level technique which involved intercepting and reimplementing the C library calls.

Other developers used the work that Epsilon and RealityMan did to create emulators that could run games made for recent consoles. For their part, Epsilon and RealityMan won the respect of the emulation community. But the fruits of their hard work went up in flames soon after when Nintendo threatened to sue them. UltraHLE was discontinued as a result.
Following the leak of UltraHLE’s source code in 2002, UltraHLE 2064 was released a year later. Some people have dismissed it as a hack of UltraHLE but that is false.
UltraHLE 2064 is a new version of the original emulator that was based on UltraHLE’s source code. The original UltraHLE team has nothing to do with this program. The emulator was designed to improve upon RealityMan and Epsilon’s work.
However, by the time it came out, more powerful emulators had already flooded the market. UltraHLE 2064 failed to achieve the same success as the original emulator. It is still around but the official site is de-registered.
This version of UltraHLE can play more games. Besides fixing the speedup music issues that people had, not to mention the flashing GUI problems, it also improved third-party video plugin support.
How To Install UltraHLE 2064?
Step 1. Download the most recent version you can find.
Step 2. Extract the files from the zip folder.
Step 3. Run the executable file
How To Use UltraHLE 2064?
The program may confuse people that are new to emulation technology because it uses a command line. Most older emulators have the same issue. This doesn’t bother experienced gamers.
They do not need a GUI to configure and run emulators. But if you don’t have that sort of experience, you should download the full UltraHLE 2064 installer. It has all the relevant files and plugins.
As far as the ROMs are concerned, you can just drag and drop them onto the executable file.
Conclusion
You don’t have to use UltraHLE 2064. There are superior emulators on the internet. But this one is free, so you don’t lose anything by downloading it. Additionally, it is compatible with a decent collection of games. If you don’t mind the bugs and glitches, or the fact that the emulator hasn’t received an update in several years, you can have quite a bit of fun with UltraHLE 2064.
