How entries are checked
Each claim comes from a page I opened and can quote. The quote sits on the game page next to its link. A developer or publisher page counts as a primary source. Press coverage counts as secondary and lowers the entry's confidence.
Status labels
Yes means a source states the feature works. Partly means it works for some platform pairs or some data. No means a source states it is missing. Announced means a source said it is coming and I have not seen it in the shipped game. Unconfirmed means I found no statement either way.
Staleness
Cross-save support changes with patches. The checked date on each entry shows when I last read the source. Treat anything older than a few months as a lead to verify, and check the publisher's own support page before you buy.
Corrections
Send corrections, with a link to the source, to crosssave@alleyne.dev.
