A later PC release appeared in 1986 which runs on any video card. The IBM version was originally on a self-booting disk it is incompatible with video cards other than CGA. The Commodore 64 had both a disk and cartridge release, with the latter having 32 levels. The VIC-20 version was released on cartridge, including the level editor. The original microcomputer versions were for the Apple II, Atari 8-bit family, VIC-20, Commodore 64, and IBM PC.
Lode Runner was originally released on June 23, 1983. ( November 2017) ( Learn how and when to remove this template message) Unsourced material may be challenged and removed.

Around Christmas of 1982, he submitted the game, renamed Lode Runner, to four publishers and received offers from all four: Sierra, Sirius, Synergistic, and Broderbund.
Smith borrowed money to purchase a color monitor and joystick and continued to improve the game. In a 2010 interview, game designer John Romero claimed that Smith added the level editing function at the request of neighborhood kids he had testing the game, and "a ton" of the levels they designed ended up in the final game. Smith was given a $10,000 advance by Broderbund to develop the inter-square animation, and to provide 150 levels of play. Smith's new game would be one of the first to include a level editor for user generated content, allowing players to create levels for the game. It was too primitive for an acceptable commercial product as Broderbund wanted detailed pixel-level movement. Miner, like its text-based Kong predecessors, had only simple animation where characters move across the screen in block increments. Unfortunately, it does not fit within our product line." He submitted a rough version to Broderbund around October 1982 and received a one-line rejection letter in response to the effect of "Thank you for submitting your game concept. Through the end of the year, he refined that version, which was black-and-white with no joystick support. Over one weekend in 1982, Smith recreated a crude, playable version in 6502 assembly language on an Apple II+ and renamed the game Miner. When Kong was ported to the VAX, some Pascal sections were mixed into the original Fortran code. The game was programmed in Fortran using ASCII character graphics. Kong was soon ported to VAX minicomputers, which had more terminals available on campus. Kong was written for a Prime Computer 550 minicomputer limited to one building on the UW campus. Bratsanos later left the project to pursue his studies, and Smith continued to develop Kong into the prototype of what later became Lode Runner. Following the release of Nintendo's arcade platformer Donkey Kong that year, the three students began working on a program called Kong, which evolved the concepts of Suicide. Īt the University of Washington in 1981, Bratsanos met two other students, architecture student Douglas E. This novel design later evolved into the concept of a level editor. Due to his lack of programming experience, there were no pre-programmed levels, but he instead built "an engine that could interpret a game level and then run a processing loop on the monsters". He began writing a Commodore PET program called Suicide, using simple text-based graphics. Bratsanos was intrigued by his friend's description of the concept, and wanted to develop it further. Around late 1980, high school student James Bratsanos heard from a friend about a new arcade video game, Space Panic by Universal, which involves climbing platforms and ladders while digging holes to trap monsters.
