Ticky has been tinkering with the innards games most of her life, ever since decompiling games on her Casio Calculator in high school.
She's only really built one (at the time of writing). It was a school project, which was kind of cool. She made a platformer with sprites out of the The Simpsons arcade game on the now very much defunct Klik n Play game engine.
For obvious reasons that will not be distributed. ;)
