This is Fairlight for Atari 8-bit, isometric arcade adventure from Bo Jangeborg, released in 1985 for ZX Spectrum and later in 1986 for C64 and Amstrad CPC. Atari version has been ported from C64, fixing major weak point of C64 version - slowness. Fairlight on ZX Spectrum is highly regarded game - at the moment its #1 game by World Of Spectrum visitors (http://www.worldofsp.../bestgames.html), the other game from #1 is Great Escape, also ported to Atari 8bit by me.
Game requires 64KB RAM, works on both PAL and NTSC machines, as well as CPU-upgraded Ataris.
Music for both game and intro has been prepared by Wieczór. Music supports stereo Pokey, but works correctly on mono Pokey as well. Atari graphics (loading, title and credits screens) have been prepared by Jose Pereira.
Game has built-in trainer: just press T on start screen.
I am also releasing full source code with all assets. Please refer to readme.txt for the detailed description how to build the game. Game itself is built on top of binary image of C64 version, with patches for input (joystick and keyboard), graphics and sound routines. For graphics I am using C64 bitmap-like mode with 256 pixels wide screen. With this layout, I had only to replace one routines which calculates screen address for given x and y coordinates to make video work. There are also several optimizations implemented.
Merry Christmas and enjoy new game!
