Summary: We're provided a file containing the save state of a computer implemented in Conway's Game of Life (GoL). It'sa modified version of [Quest for Tetris](https://github.com/QuestForTetris/QFT). The CTF problem is the same CPU implementation, but with different ROM values. Solving the problem required dumping the ROM from the GoLfile, writing a disassembler for instructions in ROM, running those instructions in an interpreter, and figuring out theinitial starting value in RAM slot 1 to get the program to write the flag.
