Core library guide

Import core library into your project

import "github.com/rdzhaafar/emu6502/core"

Initialize the system bus and write the program to it. For this example, we're going to write

    LDA #88 ;load the accumulator with "88"

which, translated to 6502 machine code is

    A9 88

bus := core.NewBasicBus()
bus.Write(0x0000, 0xA9)
bus.Write(0x0001, 0x88)

Then, initialize the registers and lastly the CPU itself.

registers := core.NewCPURegisters()
cpu := core.NewCPU(bus, registers)

You can then execute the program by using the Execute function.

cpu.Execute()

You can send an interrupt to the cpu using cpu.Interrupt. To send a non-maskable interrupt, use cpu.NMInterrupt. To reset the cpu use cpu.Reset.
