An experiment in building a small PC has unfolded across the fields of Terraria. An enthusiast tried testing a game within a game

From Scratch presented an interesting project to the Terraria community. He built a 32-bit computer inside the sandbox game.

To bring his idea to life, he used various Terraria mechanisms, such as the Logic Gate Lamp (Logic Gate Lamp). He succeeded in building the computer, but something happened during testing.

Terraria turned out not to be quite ready for such a gigantic structure (a PC) being assembled inside the game. From Scratch carried out optimizations, made a mod, and sped up the PC by 50,000 times: a leap in performance from ~0.1 Hz (0.1 instructions per second) to 5,000 Hz (instructions/sec).

Quite predictably, one of the first questions addressed not the implementation at all; the user was interested in running DOOM. For now, this Terraria PC cannot run DOOM, but the developer wants to try running a simplified version of the shooter in the future.
