allegro and cache here , i really never checked them thourougly to see what was the best , both do what i want and both is always mounted (as cd0 and cd1: respectively) but 1 thing is for sure , some cds (nightlong) required me to use allegrocdfs to get the cd name listed properly and i needed no assings for it etc.
(as a note , nightlong was fixed on this issue later on , and i use the new versions now so that bug aint troubling me anymore.)
cheers
