N64 CPU Instruction Timing (NTSC) using CP0 Count Register. Based heavily on N64 'Bare Metal' CPU Instruction Timing (NTSC) Test Demo by krom (Peter Lemon).

Code can be compiled using the bass assembler (by byuu). I've used the version by ARM9 with MIPS/RSP/RDP output.
Special thanks to PeterLemon for his awesome N64 assembly library. It's a great learning tool and a resource with lots of utility for better understanding the N64 hardware.

How to Compile:
All the code compiles into a single binary (ROMNAME.N64) file. Using bass Run: make.bat
