As Boogerman pointed out on Discord, the Section Z games in Capcom Z80 have 'variant_select' in the JSON rather than 'core_select'. This fails on his JSON validator. The JSON still work on their own, though, because if a core isn't specified, it'll select the first one in the list. But, for posterity and correctness, may as well update them.
