Current version of the NES emulator that I am working on, I have learned so much about the console during the course of programming this. Currently functions for a couple of games, only those classified as NROM or UxROM. Currently the CPU functions correctly, the PPU is mostly working, and the sound chip need to be implemented-once I switch from using SDL to SFML. This is pretty much an alpha version that I am going to continue working on. The source code is here.

Space Invaders Emulator

This was an emulator that I wrote with the intention of learning more about how games are made in lower level environments. I learned some assembly along the way and a couple of neat optimization tricks. Also doing research for these systems is tedious but immensely rewarding when you get the emulation to work correctly. The source code can be found here.
Minesweeper(Java)
A fairly basic version of minesweeper I created in java using swing and awt. It features customizable difficulty and score tracking. The Source code can be found here.
