Project technical debt

Entries about one library or component are in debt, one file per library or component, under the same sections as this page. Entries that belong to none stay here.

Build

• Building on Windows requires a specific version of mingw - MinGW-w64 GCC 15.2.0 (winlibs-gcc15, x86_64-ucrt-posix-seh)
• Even compiled prx libraries on Windows require nearby (static linking of these dependencies causes conflicts):
  • libgcc_s_seh-1.dll
  • libstdc++-6.dll
  • libwinpthread-1.dll

Direct memory

• Windows direct-memory backing reserves a paging-file section and commits each mapped guest page before setting its protection. Committed physical contents remain in the section across unmap/remap and are released when the backing and its remaining views are destroyed; commitment is not recovered merely by unmapping a page. Linux retains its existing backing. Peak gameplay memory and Windows versions other than the tested host remain unverified.

Silent stubs

Throughout the project, every function at every stage either does exactly what it's supposed to or throws an exception. Everywhere... except:

Unknown function info

• AudioIn and NpSessionSignaling exports added without an implementation have assumed signatures
• Font, Http2, Net, Ssl, SystemService and libkernel exports imported by PPSA12544 and added without an implementation have unknown signatures
• The Share, NpTrophy2, NpEntitlementAccess and WebBrowserDialog exports imported by PPSA12544's Unity plugins and added without an implementation have unknown signatures
• Acm, GameLiveStreaming, Net, NpEntitlementAccess, NpManager, NpWebApi2, VoiceQoS, WebBrowserDialog and libkernel exports imported by PPSA14632 and added without an implementation are declared without parameters

Functional

• Cancellation coverage checks deferred request handling and recovery, not full asynchronous support or console ABI compatibility. Cancellation during file/socket I/O, sleep interruption, cancellation versus exit/detach, condition signal conservation under cancellation, and safe rejection of non-null invalid or reclaimed thread handles remain unverified. No console title or homebrew establishes the cleanup NIDs or buffer layout. Accepted asynchronous mode currently has no diagnostic for its deferred behavior.
• --to-intel guest module trampolines are covered only by a synthetic relinker test; no game title has been verified with them on Linux or Windows.
