BES

An attempt to code a NES emulator in BeefLang. Making each component of the NES independently.

Components

1. CPU (Central Processing Unit)

6502-based CPU with no decimal mode (still programmed in to pass tests but disabled)

2. Memory Mapper

Memory mapper to handle memory mapping for different cartridges. Just implemented a basic memory mapper interface and created a 64kb memory array that implements it.

3. PPU (Picture Processing Unit)

NES' PPU, responsible for rendering graphics. Just started.

4. APU (Audio Processing Unit)

NES' APU, responsible for generating audio.

5. Input Handling

I guess this goes with the memory mapper. Will work on it

6. Cartridge Handling

Cartridge handling to load NES ROMs. Also think it's linked to the memory mapper.

7. Debugging Tools

Debugging tools to help with development.

Progress Overview

Memory Mapper	Work in Progress (WIP)	Basic memory mapping implemented
PPU	Work In Progress (WIP)	Just started
APU	TODO
Input Handling	TODO
Cartridge Handling	TODO
Debugging Tools	TODO
