A 3-letter opcode for the 6502 processor. This opcode increases the 8-bit value in the main register (also called the Accumulator) by 1. This wraps around when the end is reached (that is, increasing a value of 255 ($ff) by one turns the value into zero).

Back to the 6502 opcodes metanode

INC - International Network of Crackers, an old pirate group from days yore, when one proved their mettle on BBSs and 31337 actually meant something. INC's major competitor in the 'scene' was THG. To be a distribution site for INC or THG was to guarantee a wealth of quality users, not to mention a visit from your local FBI agent.

The good 'ol days.

1. Abbreviation for incorporated.

2. A 6502 instruction that adds 1 to a memory location.

  • Function: N++
  • Updates flags: S . . . . . Z .
  • Opcode numbers:
    dp    $E6
    abs   $EE
    dp,x  $F6
    a,x   $FE

Don't forget to add 2 cycles, as INC is a read-modify-write instruction.
