A Space Invaders emulator in C#
Aren't there already many space invaders emulators out there? Yup. Are they better than this one? Probably
I didn't really intend on creating an emulator for space invaders, I was helping someone in the /r/emudev slack (now the /r/emudev discord) with questions that they had about the Intel 8080.
That turned into implementing parts of the i8080, which then turned into this.
