on GitHub

FPKG (pkg) support is experimental, and a pkg game can run worse than
the same game in zstd packs. If a game stutters as a pkg, try it in zstd
packs and tell us in an issue.

What's new

• A new file index: every game's index is kept in memory as one compact
  table, built once when the game starts. It needs less memory, has no
  fixed 48 MiB cap, and opening a packed file no longer reads its path
  from disk.
• /data/ampr_cache no longer shows in a file explorer.

Fixes

• Large games that would not start with index tables need ... MiB, over the 48 MiB: Final Fantasy XVI (#53, #67), Demon's Souls (#61) and
  Returnal (#72).
• New game crash in Marvel's Spider-Man: Miles Morales (#63): the save
  icon path ran out of stack on the game's save thread.
• Stuck on "Closing..." with CE-108255-1 in AI LIMIT (#60), and saves
  that could not be created (#64): a busy save mount is now passed back
  to the game instead of being retried after unmounting its other saves
  (#66).
• Loading stuck at 20% or 60% after loading a save in Horizon Forbidden
  West (#23, #68).
• Folder handles of packed folders are now numbers below 1024, since some
  games reject larger ones (#58, #70).
• A folder is no longer hidden by a file with the same name in another
  case.

Thanks

• @jamesst20 tracked down the Spider-Man crash from core dumps (#71),
  moved folder handles below 1024 (#70), wrote a core dump payload, and
  dug through three Wolverine crash dumps (#48).
• @strongt1me fixed the save mount retry (#66), documented the
  ampr_emu.index rules for packer authors (#69), and found from the
  logs why Demon's Souls and FF16 did not fit in memory (#61, #67).
• @BXYMartin, in a first contribution, fixed the Horizon Forbidden West
  loading hang (#68).
• @dotpinheiro for the save mount investigation in #62.

Thanks to everyone who tested builds and sent logs: @Mrfireos (#60),
@WalkerAllen96082 (#61), @Zedan015 (#67), @fecent (#72), @xavi871b (#64),
@myselfayman2-sys and @linchiech (#63), @Libraaaaa2792 (#65),
@olizo53 (#48) and @PrivatePasta (#52).

How to use

FPKG games: launch with kraken-mount.

zstd, LZ4 and folder games: copy libSceAmpr.sprx into the game's
fakelib/ and mount the game with ShadowMountPlus (disable fakelib update
in its settings) or Kraken Mount.

zstd and LZ4 packs can be made with
ps5-dump-forge.

Please keep reporting how your games run with the game report form, and
name the format: pkg, zstd, LZ4 or folder.
