Dreamcast TEST GD-ROM "GD Drive repear program ver 0.1" en liberté

Laurent C. de notre beau forum et Darcagn, du forum assemblergames, ont chacun récupéré un GD-rom un peu particulier. Ce dernier en a dégagé les fichiers que contient le Dreamcast TEST GD-ROM "GD Drive repear program ver 0.1" (c'est son nom).




Le travail de Darcagn sur le GD-rom a été fructueux. En effet les deux GDI que contient le support ont pu être extraits : DCCheckerRepair et GDDriveRepair. Leurs noms laissent penser que ces applications permettraient la réparation (ou du moins le diagnostique de panne) sur la console pour la première et plus précisément la lecteur GD-Rom pour la seconde.


Voici le copié-collé du readme, traduit du japonais, contenu dans GDDriveRepair en lien de téléchargement ci-après :

Il ne s'agit pas de la première diffusion de disque DCCheckerRepair. Celui-ci est du même genre que les précédents.
L'archive GDDriveRepair contient des dossiers dans sa partie haute densité hébergeant une autre version différente de DC Checker, mais Darcagn 'a pas réussi à les utiliser pour le moment.
