The NES' impressive library of games was written using 6502 assembly language. Compared to assembly languages for modern processors, 6502 assembly is relatively simple, with only 53 possible instructions, one accumulator, two index registers, and a 256-byte stack.
C, C# and C++
Nintendo is using Unreal Engine 4, and Miyamoto says they have it 'mastered' - Polygon.
The game was written almost entirely in C and was compiled using a Silicon Graphics IDO compiler. 2 The compiled code was written to the read-only memory (ROM) chips contained in Super Mario 64 cartridges. The law concerning the reverse engineering of software is fuzzy, to say the least.
Back in the days of the NES, there was no programming language that compiled fast enough to run a good game that pushed the NES to its absolute limits. (It's a combination of the NES not having a strong enough CPU and compilers not being as good back then). Programmers had to write NES games using the same bytecode - set of instructions - that the NES used. Even C is high level compared to this assembly programming.
Here is a great resource from someone who created a NES game in modern times:
