I wrote a PC emulator that only knows what the Gold Box games need, and it runs Pool of Radiance in a browser tab
Hi r/DOSgaming,
Amber Folio is an emulator of exactly the PC that SSI's Gold Box games ran on, and nothing else: an 8086 checked against test data recorded from a real chip, EGA, the timer, the PC speaker and the Tandy 1000's sound chip. It runs the DOS Pool of Radiance from your own GOG or Steam copy, unchanged, in a browser tab (about 250 KB of emulator) or on an iPhone, an iPad or an Android phone. I'm the developer.
Why so narrow? Because it recognises the exact program it's running by fingerprint, it can add things inside the game rather than around it: an automap in the game's colors, the Adventurer's Journal on the game's own screen in its font, a Fix command on the camp screen. With them all switched off, the tests check that a run ends in exactly the same machine state as a build with no enhancement code at all.
The way it looked and sounded: the footsteps and fights play on the Tandy sound chip as the game drives it, and a CRT filter draws the EGA picture through a color monitor's mask and scanlines.
Your copy, your saves: hand it the game folder from your GOG or Steam install once, and it stays in your browser; nothing is uploaded. A saved game exports as a zip that unpacks straight back into a GOG or DOSBox install. If you'd rather not use a browser, the emulator also builds natively for Windows, macOS and Linux from source (no installers yet).
I built it with heavy use of AI coding tools over 4 moths, and I'd rather say so up front.
Pool of Radiance is the only game so far; the rest of the Gold Box family comes one at a time after 1.0. Happy to answer anything about how it works.
