Pinball Dreams Deluxe reverse engineered into a native C port

Two Claude agents reverse engineered the GOG version of an MS-DOS pinball game and wrote a native C port, then added quality-of-life features.

The full story

DropIn Classics is a project converting classic MS-DOS games into native Windows, Linux and macOS programs with no emulation. The first release is Pinball Dreams Deluxe: the whole game, taken from the GOG version, was reverse engineered and converted to C code, which the maker says took two Claude agents (Opus 5.5) a few days.

The maker tested it on all three platforms (not Steam Deck) and says it works fine, though testing was limited to their own play. With the C source in hand, Claude also added a launcher menu, mappable controller support, audio settings, direct-to-table launch and toggleable options to skip intros and speed up bonuses. The ports need the user's own GOG copy and include no game data.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count).
