    Libs: add libSceDiscMap HLE exports (ported from Kyty) (#79)

    Ghost released this 2026-07-12 11:24:11 -04:00 | 526 commits to 1016_part3 since this release

    Port the libSceDiscMap stubs from Kyty (InoriRus/Kyty, MIT) into the
    SysAbiExport model. Disc-installed titles probe these NIDs on most file
    accesses to decide whether a read must be redirected to the disc drive;
    answering that every request is already resident on internal storage
    keeps I/O on the regular file system path instead of failing with
    unresolved-import errors.

    • sceDiscMapIsRequestOnHDD (lbQKqsERhtE): validates args, writes 1 to
      the result pointer, returns 0
    • fJgP+wqifno / ioKMruft1ek: zero-fill the three output pointers,
      return 0 (names not present in ps5_names.txt; kept as descriptive
      Unknown exports like the existing sceKernelUnknown* convention)
    • DISC_MAP_ERROR_INVALID_ARGUMENT (0x81100001) on null pointers,
      matching the documented libSceDiscMap error range
    • optional tracing via SHARPEMU_LOG_DISCMAP=1
