In 1983 Matthew Smith and published by Bug-Byte released the well known classic of Manic Miner for the ZX Spectrum. Although it was later released again by Software Projects, it was the first game in the willy series and was inspired by the Atari 800 game 'Miner 2049'. Not only was it voted number 25 in the Your Sinclair official top 100 Spectrum games of all time, but it had in game music, and sound effects, and if you ever remembered Jet Set Willy, a high amount of addictive gameplay. But today's news isn't for the ZX Spectrum, but a developer by the name of Tezz has ported over the original game to the Atari XL/XE!
Although a much deeper discussion on the game is found on the Atari forums, we can say that this is a faithful port of the original Manic Minor, and as the developer said "after being inspired playing Miner 2049er on the Atari, it is only fitting that we now eventually have a conversion back to the Atari". So far from what we can tell however, the major difference is the game speed delayed to run roughly at 140% speed on PAL systems compared to the original. As the ZX Spectrum version felt more slow motion compared to the PC remake of Manic Miner, which gathered more positive comments.
For further information it is well worth reading the main discussion thread and downloading it to see just how good this conversion is ( HERE )
