See the writeup for this project: Statically Recompiling NES Games into Native Executables with LLVM and Go

Note: This project is discontinued. See the above article for the explanation.

Features

• Recompile NES games into native executables
  • Only known supported game is Super Mario Brothers 1
• 6502 assembler / disassembler
• Unpack & disassemble NES roms and then put them back together
• Adds a small custom ABI which gives you putchar and exit for making test roms.

Getting Started Developing

1. Set up your $GOPATH. Make sure the bin folder from your go path is in $PATH.

2. Install the lexer:

   go get github.com/blynn/nex
   

3. Install llvm-3.1 or llvm-3.2 from your package manager.

4. Install gollvm (replace 3.2 with 3.1 if you want):

   export CGO_CFLAGS=$(llvm-config-3.2 --cflags)
   export CGO_LDFLAGS="$(llvm-config-3.2 --ldflags) -Wl,-L$(llvm-config-3.2 --libdir) -lLLVM-$(llvm-config-3.2 --version)"
   go get github.com/axw/gollvm/llvm
   

5. Install the rest of the go dependencies:

   go install
   

6. Install the C dependencies:

   sudo apt-get install libsdl1.2-dev libsdl-gfx1.2-dev libsdl-image1.2-dev libglew1.6-dev libxrandr-dev
   

7. Compile, run the tests, and then try it!

   make
   make test
   ./jamulator -recompile game.nes
