Demakes of the latest popular 3D games are often designed to emulate how they might look on hardware a few years old, sometimes a couple of decades. Taking Baldur's Gate 3 and getting it to run on something that's over 40 years old, though, is on a whole new level—but that's exactly what one ingenious software engineer has managed to do.
Strictly speaking, the project isn't an exact clone of BG3, nor could it be, as the hardware in question is a TRS-80 Model 100 computer—arguably the world's first laptop.
