Hi all,
Here's a script to run MotoRacer from GoG. The main issue with this early 3D game is that it requires a 16bpp display (65536 colors), a setup that is now uncommon.
Under X, you need to restart the server to change bpp, but the script below can also use Xephyr to emulate a 16bpp display (with software rendering, but that should not be an issue with a modern CPU).

Enjoy!

Très intéressant ce script. Petite question: pourquoi le rendu des graphismes est-il si différent avec la version 1.3.23 de wine?

Salut,

Je ne sais plus trop pourquoi j'ai pris spécifiquement cette version, alors qu'à priori la 1.3.37 était déjà sortie à l'époque, et mes notes ne le mentionnent pas non plus.

Peut-être que les versions ultérieures ont le même problème que les 1.4, ou bien il y avait une différence de performance, ou d'autres soucis... Si je me rappelle bien il y a eut des turbulences dans le support du son dans les dernières 1.3.x, j'étais peut-être simplement de mes résultats de tests avec la 1.3.23...

Ou alors tu as trouvé qu'effectivement ça marche très bien uniquement avec cette version, auquel cas la réponse doit être dans les sources de Wine ;)

Je viens de tester le script, il ne fonctionne pas sous Ubuntu. J'ai commencé à déboguer:

- la variable BPP n'est pas renseignée, la commande permettant d'obtenir le code bit des couleurs (ligne 81) ne fonctionne pas

- le jeu plante dès le démarrage dans Xephyr
