En fait, non. Justement.
Cette build n'a pas besoin des switches.
J'en ai activé 2, pour des histoires de synchro: -synchrefresh et -triplebuffer (Hasary, tu devrais essayer ça).
Pour le reste, Groovy Mame ne fait pas le hwstrech par défaut et switchres automatiquement de base. C'est une build spéciale Cab, comme le faisait Mamecab32.
Je suis sous XP.
Mea Culpae

, en effet maintenant il a réussi à l'intégrer (en discussion à l'époque)
Je viens de jeter un coup d'oeil à son diff et les commentaires sont supers ^^
