We Ranked Every 6502 Instruction - From the Commodore 64 ROM

The MOS 6502 microprocessor was released September 1975, and has now turned 50 years old. To celebrate, we're counting down the top 50 instructions as ranked by use in possibly the most-executed 6502 software ever written: the built-in BASIC and KERNAL ROMs of the best-selling Commodore 64 home computer. We'll also look at a bit of microprocessor history, another contender or two for software to examine, and give a real-world use for every single instruction, as found in the 16KB of ROM code in the C64. Happy birthday to the 6502 processor family! Links: Michael Steil's Page Table Dot Com: https://www.pagetable.com/ C64 BASIC & KERNAL ROM Disassembly: https://www.pagetable.com/c64ref/c64d...
