Recover the Mac sound TXT descriptor arrays in constant data and stack storage

checked · by eejitgames · submitted 2026-11-07

Mac SOUNDHDR_Init copies two constant TXT field tables into stack objects still stored as one-byte undefined values. Decode the940 source bytes as24/23 existing20B D2BinFieldInputStrc records, including one end/type0 terminator each; all45 active names resolve to sound/environment columns. Native memcpy lengths480/460 and both dispatcher argument bases independently confirm the extents. Type both source globals and both stack copies as those arrays, and name only their default labels/locals. The source arrays end at003d08e4/003d0ab0; stack ranges fit without overlap, with4B between them. Current environment decompile over-infers464B. Windows already types corresponding local arrays24/23, corroborating the Mac bytes without copying its differing sound-record layout.1396 only fixes the dispatcher API;933 only the initializer prototype. No new struct/callback type or measured generated-code/runtime improvement is claimed.
