Leako, a ColecoVision clone project, has reached a critical buildability milestone with revision seven. The primary focus was enhancing reliability, driven by persistent component shortages and discovered reliability issues. USB power input replaces the barrel jack, addressing polarity concerns and leveraging widely available adapters, though regulation quality remains a variable factor. 74LS541 chips became a bottleneck, requiring over a month of waiting due to a TI fabrication delay, forcing a switch to a Maxim alternative. Controller ports were redesigned to prevent twisting-induced solder joint failures, though a footprint oversight initially weakened strain relief pins.

Color-coding for RCA jacks was introduced to aid assembly. A custom KiCad BOM generator script was developed to streamline ordering, handling Digi-Key field mismatches and enabling multi-project bag labeling. Component shortages were a constant headache, impacting parts like the RCA jacks and necessitating component substitutions. The project demonstrates practical engineering solutions under constraints.
