Donkey Kong Foundry (hack) [Hack]

Donkey Kong Foundry is a critically acclaimed fan-created ROM hack of Nintendo’s iconic 1981 arcade classic *Donkey Kong*, developed by independent retro modders and released publicly for arcade emulation platforms in 2017. Unlike the original’s construction site setting, this hack reimagines the entire game around a gritty industrial steel foundry, while retaining the tight, satisfying core gameplay that made the 1981 title a foundational piece of video game history. In this modified version, the titular Donkey Kong has kidnapped Pauline and taken refuge at the top of a molten metal processing plant, and players control Jumpman (the protagonist later rebranded as Mario) as he climbs four entirely new, hand-designed levels filled with reworked obstacles and fresh challenges. The hack replaces the original’s wooden barrels with glowing molten metal buckets that roll faster and bounce more unpredictably, adds new hazards like steam vents, shifting conveyor belts, and falling steel ingots

Game Guide

Mastering Donkey Kong Foundry relies on a mix of knowledge of the original Donkey Kong’s core mechanics and awareness of the hack’s unique new systems. First, familiarize yourself with the adjusted movement and obstacle timings: molten metal buckets move 22% faster than the original game’s wooden barrels, and they bounce 30% higher when hitting gaps in the girders, so you will need to time your jumps 0.2 seconds earlier than you would in the base game to avoid taking damage. When you encounter the conveyor belt levels (stages 2 and 4), watch the small indicator lights above the belt at all times: a red light means the belt will shift to move left in 2 seconds, while a green light signals a shift to the right, and standing too close to the edge of the belt during a shift will knock you off the platform instantly. Steam vents on stages 3 and 5 erupt on a fixed 3-second cycle, so count silently as you approach them to time your jumps perfectly. The hammer power-up works slightly differently in this hack: it lasts 2 seconds longer than the original, but you cannot collect hidden foundry coins while holding it, so avoid picking it up if you are trying to collect all coins to unlock the secret bonus stage. For high-score runs, prioritize jumping over multiple molten buckets in a single jump: each extra bucket you clear in one leap adds a 1,200 point bonus, compared to just 300 points for clearing a single bucket. Finally, on the final boss stage, Donkey Kong throws steel ingots in a repeating three-throw pattern: he will throw one low, one high, one directly at the ladder you are climbing, so pause for half a second after the third throw before climbing up the next ladder section to avoid getting hit.
