Eugen focused on stabilizing the LXH Attack Chopper Emulator within the OpenRakis/Spice86 repository by addressing memory alignment issues related to DOS system variables. Using C# and system programming expertise, Eugen implemented a fix that ensured fields accessed via INT 21h, function 52h remained within the correct memory block, preventing potential overwrites and improving emulator reliability. The work involved adjusting the DosSysVars layout to maintain proper access paths for DOS-era variables, reducing memory-related risks in emulation flows. Although the period included only one bug fix and no new features, the solution demonstrated careful attention to low-level emulator stability and correctness.
