This issue focuses on system programming and ZX Spectrum hardware, covering undocumented Z80 instructions, hidden flags, overlay development for Jemmini Commander, TR-DOS drive detection, pathfinding algorithms, and a water ripple effect simulation. Hardware articles analyze keyboard ghosting during two-player gaming, IM2 mechanics, and software standardization practices. Additionally, a comprehensive technical guide explores various disk operating systems and image formats, ranging from MS-DOS, CP/M, and IS-DOS to specialized systems for Agat, BK-0011M, and Radio-86RK computers. Software coverage includes a walkthrough for the strategy game Alien, descriptions of graphics editors, Universal AntiProtector, and the Exhumator recovery utility, alongside an insider report and official results from the DI:HALT:99 demoparty.
