Titre: [Code source] de Sonic 1 MD Posté par: Miles Prower le Juin 09, 2005, 10:20:26 am Hivebrain a réalisé une nouvelle dissection de la rom de Sonic 1 MD (version : juin 2005). En la décompilant et la documentant, on retrouve ainsi une sorte de "code source" fait maison du jeu, peut-être proche du vrai code du jeu.
Cette décompilation est en assembler. Citation de: "Hivebrain" I've finally released the June 2005 version of my Sonic 1 disassembly. New stuff: - Most of the subroutines are labelled - Many things have been commented - This version compiles a lot faster - Compressed data is automatically decompressed (recompression is not automatic by default because it's very slow) - Some parts of the ASM are separated into _ANIM, _INC and _MAPS folders - The compiled ROM is automatically padded to be a "power of 2" in length (i.e. $80000, $100000, $200000) IDB, for use with IDA Pro: http://sonicology.hacking-cult.org/S1idb_June05.rar Split ASM: http://sonicology.hacking-cult.org/S1asm_June05.rar Citation Yes, there are a few unused bits of code: MoveDemo_Record - for recording demos. Just after locret_132D2 - subroutine that squashes Sonic and stops him moving. This was possibly used when Sonic runs into a wall at speed, although there's no way of knowing for certain. FloorLog_Unk - records something to do with collision. I don't know what. Just after nullsub_2 - limits Sonic's speed in the special stage. |
