Added

• Buildbot system file download — Thin libretro wrapper now auto-downloads missing system files (e.g. prboom.wad, ecwolf.pk3, MSX BIOSes, FBNeo NeoGeo BIOS) from https://buildbot.libretro.com/assets/system/ asynchronously at core startup, matching the PVRetroArchCore overlay-download pattern.
• Legacy RetroArch directory migration — When Documents/RetroArch/system/ exists (users migrating from the old PVRetroArchCore backend), relevant system files and subdirectories are automatically copied into the thin wrapper's Documents/System/<name>/ tree. Copies are idempotent; the source directory is preserved.

Fixed

• PSP flash0/font auto-seeding — Thin libretro wrapper now seeds PPSSPP font files from the app bundle into System/PSP/font/ on every core launch, matching PPSSPPGameCore.mm behavior and fixing tvOS cache-purge recovery.
• Hatari TOS path — Thin wrapper now searches BIOS/com.provenance.atarist/ for a TOS image and rewrites szTosImageFileName in hatari.cfg at launch, fixing the hardcoded Android placeholder path.
