This 8-bit demake of Baldur's Gate 3 was made for a 40-year-old laptop, and it's a massive shot of pure 1980s gaming nostalgia
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. With an 8-bit processor running at 2.4 MHz, a few kB of RAM, and a built-in 240 x 64 LCD display, there's absolutely no chance of running one of the most hardware-demanding games out there.
Alex Bowen created Mol (as reported by Hackaday) as a piece of 'interactive fanart', a 1980s-era tribute to the first act of Baldur's Gate 3. So it's not a line-by-line perfect recreation of the game but if you watch the video above, many of the main events in the first act have been recreated.
Despite the limitations of the display, there's an undeniable charm to the simplistic sprites, and I'm sure BG3 fans will easily recognise the various locations, thanks to handy (or should that be Tandy?) text descriptions alongside them.
As someone who got into games and programming in the early 1980s on a Z80-powered home computer, I immediately got floods of nostalgia, especially seeing the assembly code used to create the demake. Where my first system only had 1kB of RAM, Bowen needed 24kB for the engine, basic sprites, and text.
Even that wasn't enough, so some ingenious tricks needed to be employed to get BG3's mountain of information, descriptions, and dialogue into a compact enough format to squeeze into the TRS-80's RAM. Today's games are hugely complex and require thousands of kB of memory to run, but most gaming PCs sport far more RAM than they'd ever need.
Forty years ago, that definitely wasn't the case, especially so when you're talking about a laptop. The TRS-80 Model
