Erik	4d36756b91	research: full acclient.exe decompilation — 22,225 functions, 688K lines ... Complete decompilation of the retail Asheron's Call client using Ghidra 12.0.4 + pyghidra headless. 22,225 of 22,226 functions successfully decompiled in 75 seconds. Output: docs/research/decompiled/ (54 files, 688,567 lines of C) Key findings already identified: - CLandBlockStruct::ConstructPolygons at chunk_00530000.c:2270 (split direction formula with 0x0CCAC033 constants) - Motion command handlers at chunk_00510000.c (0x45000005 etc) - Motion interpreter at chunk_00520000.c - Portal space UI at chunk_004D0000.c and chunk_00560000.c Next: identify CPhysicsObj, CMotionInterp, collision, and movement functions by cross-referencing against ACE's C# port.

Erik	370c6e3133	research: decompile acclient.exe terrain/physics via Ghidra headless ... Used Ghidra 12.0.4 + pyghidra to decompile 368 functions from the retail AC client binary (acclient.exe, 4.7MB, 2016). Output: docs/research/acclient_decompiled.c (13,560 lines) Confirmed the decompiled code matches ACME's ClientReference.cs: - ConstructPolygons split formula at ~0x00532610 with constants 0x0CCAC033, 0x6C1AC587, -0x421BE3BD, -0x519B8F25 - Same 2.3283064e-10 float comparison for split direction Regions decompiled: - 0x530000-0x536000: CLandBlockStruct + terrain (85 functions) - 0x536000-0x540000: nearby functions (168 functions) - 0x5A9000-0x5AB000: LandDefs region (111 functions) Tools: tools/decompile_acclient.py (pyghidra headless script) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-12 23:18:27 +02:00
