# lib68k
Motorola 680x0 Standalone Emulation Library
# Motive:
The motive behind this repository is to provide a surrogate means of aiding in relevant Motorola 68000 developments.
Such is the case with one of the many ambitions, to create a dedicated OS Kernel specifically for this series of microprocessors
Created using ANSI C99 standard, this project aims to promote an ease of use means of creating a library that emulates the likeness of these microprocessors
# Usage:
```
git clone this repository
make clean
make
```
the following output will vary depending on system:
### Windows:
```
lib68k.a
```
### UNIX:
```
lib68k.so
```
the makefile in question is universal, allowing for ease of use compiling on other systems
# Example:
Below is an example provided to showcase how the ``OPCODE_HANDLER_TABLE`` is able to store and evaluate respective Opcodes and Operands
You can find the provided example Assembly code [here](https://github.com/hazzaclark/lib68k/blob/main/hello.asm)
# NOTE:
Some of the Opcodes and their extended addressing capabilities such as IMM, EA, DI, PI, etc - are all reserved for an eventual expansion on this Library.
As of right now, I wanted to focus on getting everything working with 68000 emulation to prioritise [mdemu](https://github.com/hazzaclark/mdemu/blob/main) developments
