User blog:Jer155/how do i make a stage exclusive to certain characters?

i don't know if you know what i mean by the title, but if not, here's a more clear explanation:

i want to make a stage for the sub-boss in arcade mode, so i put it in, did the 'stage=mystage.def' stuff, but it appears when fighting characters that are not the sub-boss too. how can i fix this?

i figured i could assign every character his/her own stage, but for that, i would need a hell of a lot of stages for that. is there any other ways to take care of this problem?

please, help me.
