Unfortunately, I am not legally allowed to share most of my source due to confidentiality agreements but these are some of my hobby projects that I tinker with from time to time. Most of them are WIPs that I update when I get a chance.

Puzzle Cube

discontinued

Rubik's Cube mobile game for Android.

This was actually my first Java project. The only reason I started learning Java was due to the allure of Android development. R2 was on the play store for awhile until Google removed it due to copyright. R3 is unfinished because I abandoned it when it was removed. They are pretty old and I would use Unity3D or Unreal nowadays. You can download the APK for R2 if you want to see it in action.

BrewOS 64

active

64-bit hobby operating system for the x86_64 architecture.

There are many pieces that I am still converting from my 32-bit implementation. The boot loader has also seen some refactoring. Lately, I have been working on replacing my legacy BIOS boot loader with UEFI.

B1CPU

Homebrew CPU assembler (and eventually simulator).

I have been working on my homebrew CPU off and on for years. The design has been through many iterations as I end up making it more complicated than I care to. I have kept my latest design as simple as possible while retaining some of the features I wanted. I have been working on an assembler to test and tweak my instruction set. Next I will work on a simulator so I can actually see my test code in action. My hope is to finalize my design so I can start building my CPU.

Space Ace

Player vs player shoot 'em up game for the NES.

After recreating some of my Atari BASIC games in assembly, I thought it would be neat to make a game for the NES. It is not playable yet but I hope to come back to this one soon. I really enjoy working with the 6502 instruction set.
