Feb 1, 2025February 2025 focused on data integrity and emulation fidelity for the mamedev/mame repo. Delivered a targeted bug fix to correctly identify the Eternal Champions: Challenge from the Dark Side US version as a clone of the PAL version by updating megacd.xml, improving clone resolution, data integrity, and emulation accuracy. This change reduces misclassification risk and ensures correct ROM relationships for downstream tooling and user reports.
