Charles MacDonald<\/em> nous fait part de ses avanc\u00e9es en mati\u00e8re de d\u00e9cryptage des jeux Sega.
\nAu menu du jour, Wonderboy III, FlashPoint et E-Swat, ainsi qu’un soup\u00e7on de d\u00e9sassembleur et de System24.<\/p>\n

Il a d\u00e9crypt\u00e9 une version \u00e0 priori plus ancienne de Wonderboy III (317-0085). Toutes les versions de ce jeu devraient \u00e0 pr\u00e9sent \u00eatre \u00e9mulables.<\/p>\n

<\/p>\n

Il a analys\u00e9 le code du MCU de Moonwalker, et a pour l’occasion cr\u00e9\u00e9 un petit d\u00e9sassembleur, dont il fournit le source.<\/p>\n

Il a d\u00e9crypt\u00e9 FlashPoint. Comme le CPU de cette version de Flashpoint n’est pas identifi\u00e9, il demande si quelqu’un sait \u00e0 quel num\u00e9ro de CPU correspond les composants EPR-12590B et EPR-12591B. (aux possesseurs de la PCB de Flashpoint)<\/p>\n

<\/p>\n

Enfin, il a aussi d\u00e9crypt\u00e9 E-Swat, version 317-0130 (317-0129 pr\u00e9c\u00e9demment). Il ne s’agit pas forc\u00e9ment d’une version plus r\u00e9cente.<\/p>\n

<\/p>\n

Rappel :<\/strong> contrairement aux jeux CPS2 (par exemple), chaque version d’un m\u00eame jeu doit \u00eatre d\u00e9crypt\u00e9e ind\u00e9pendamment.<\/p>\n

Il a eu beaucoup de questions concernant le System24. H\u00e9las, pour d\u00e9crypter, il lui faut un dump correct du programme ainsi que le CPU de protection, et aucun des jeux System24 utilisant un lecteur disquette n’est correctement dump\u00e9.<\/p>\n

Flashpoint et Wonderboy III ont pu \u00eatre d\u00e9crypt\u00e9s gr\u00e2ce au don de CPU et PCB de Thierry ‘ShinobiZ’ Lescot, et E-Swat gr\u00e2ce au don de CPU de David Widel et au dump de Zozo.<\/p>\n

Merci \u00e0 eux <\/p>\n
