Nintendo Emulator

Current Status

• Realtime CPU, PPU, and ALU emulation

CPU

• Load iNES cartridge, parse headers, CHR, and PRG roms
• Enough features to play Super Mario Bros, Donkey Kong, Arkanoid, Gradius, and Metal Gear
• All memory addressing modes. All standard and some obscure opcodes.
• Decent cycle counting, including iffy page-boundary-crossing penalty calculator
• Memory Mapped IO with most PPU and some ALU addresses.
• Very nice disassembler output

PPU

• Vertical and Horizontal scrolling, Sprite DMA, Address Mirroring
• Per-pixel scanline advancement
• Sprite-0 hit detection, HBlank/VBlank support

APU

• Basic implementation: two square waves, enough to play SMB intro music.

Supported Memory Mappers

• NROM (iNES Mapper 0)
• UNROM (iNES Mapper 2)
• CNROM (iNES Mapper 3)

Input

• Basic joystick support

Dependency management using conan

1. Add repo: conan remote add bincrafters https://api.bintray.com/conan/bincrafters/public-conan
2. Download dependencies: ./conan-resolve-deps.sh
3. CLion/CMake will pickup dependencies automatically during build step

All 2015 goals were met!

Target Platform: Ported from Windows to OS X Primary Goals: CPU & PPU Performance, using C++14 features, scanline-accurate CPU<->PPU synchronization Stretch Goals: APU emulation, memory-mapper supports, pixel-accurate synchronization

Compatibility Goals:

• Primary: Super Mario Bros & Donkey Kong
• Secondary: other 32kB ROM + 8kB VROM games
• Stretch: Official Nintendo memory mapper powered games
