To be honest, it really doesn't matter. Any way it's sliced the versions of the DC characters that appeared in that story, along with most of the inter-company crossovers, are assumed to mirror the "main" versions in print at the time. They are essentially one offs that don't need pages, maybe a note reference about which characters where the bases for the ones that appeared, and not appearance listings.
