     For this NDS ROM I combined an asteroids style demo with a memory editing tool. My game testers had a field day with this capacity, drawing things I never would have imagined to play with!

     This ROM showcases a number of programming algorithms, such as pixel perfect collision detection and sprite management.

     Recommended emulator: DeSmuME DeSmuME

     For my graduate research project I learned to program the Nintendo Entertainment System. This required knowing 6502/2A03 assembly language and the NES's memory map on a very intimate level.

     While most "hello, world!" programs are a few lines of code, the source code for this ROM—if printed out—would be 21 pages long!

     Recommended emulator: Nestopia Nestopia

     This project is an early prototype of a comprehensive game engine developed in Unity, highlighting my ability to collaborate effectively within a team environment. Our team coordinated using Discord and a privately hosted Git server that I managed.

     Sideload to an Android phone or emulate.
