If you are looking for "indir" (download) sources or ROM files for legal backup or emulation, the community often points to the following repositories:

eBay, Mercari, and Japanese auction sites (using Sendico) often have Golden Abyss for $20–$40. A used PS Vita Slim can cost $120–$150.

A key driver for this specific search query is the exclusivity of the title. Unlike other entries in the Uncharted series, Golden Abyss remained exclusive to the PS Vita. It was never ported to the PlayStation 3, PlayStation 4, or PC. Consequently, legitimate access to this game requires owning legacy hardware and a physical copy or a digital license on a console whose store infrastructure has faced instability. This scarcity makes the game a prime target for emulation and piracy.
