The bounded hunt succeeded on its first lead. archive.org item
`play-station-programmer-tool-runtime-library-version-4.2.7z` (383 KB) is the PsyQ Runtime
Library 4.2 (LIB/*.LIB + INCLUDE, 1998-01-21) plus LIB/42PATCH/J421PD.ZIP — SCE R&D's
1998-02-26 "Libpad.lib version 4.2.1 for the Analog Controller (DUAL SHOCK)" patch, shipping
LIBPAD.LIB 4.2.1 with LIBAPI.LIB 4.2 and LIBPAD.H/LIBAPI.H/KERNEL.H.
Placed and byte-verified against the EXE (psyq_identify 0x8005CE18-0x800629DC, then
psyq_link.py per object): libpad 4.2.1 7/11 — PADENTRY, PADMAIN (760 ins, the 4.2.1 build,
exact), PADCMD, PADIF, PADPORTD, PADSEQD, WAITRC2 — and libapi 4.2 39/88 — the 21 band
trampolines, COUNTER, L02/L03, and the apicard-region C112/A50/A51/A54/A65/A67/A69/FIRST/A66/
PAD/A18-21/PATCH/CHCLRPAD. All 46 PASS. Neighbours for the record: plain libpad 4.2 and the
4.3 disc (DTL-S2340, 1998-05-18; PADMAIN 832 / PADIF 380 / PADSEQD 292) each place only 4;
4.2.1 is the unique exact match, so the game was built between Feb and May 1998.
Banked (R20): the 7z tracked under tools/psyq/ with sha256 + provenance in CHECKSUMS.sha256;
extracted to gitignored tools/psyq/lib42/ and lib421/ (the 4.2.1 headers are the band's
prototype oracle from now on); ELF in .run/obj42/{libpad421,libapi42}. Docs: psyq-worklist
"S79 task #13", SETUP archive table + §5.1 + S79 tool table, CURRENT_PHASE (#13 log; the S79
FINAL block's §5 records the archive and §6 is the re-scoped task #5 brief: link the whole
0x8005CE18-0x8005FC68 band and re-source the apicard region's libapi from 4.2).
