If they'd have put the chips on the bottom of the HuCards instead of the top they could use most of the surface for the label.

That's true. They could've just put the labels on the back side, making that the front, and had you insert them upside down into the system. That would've been interesting.

Maybe they thought that was too much space.

They probably didn't think that they'd ever cover so much of the card with chips when they originally designed the hardware, and by the time they had such high capacity cards, it was far too late to redesign the card socket.  Still, they could've made those few cards upside down and wrapped the connections around the edge to get back to the front side.

they did put stickers on the back! But only on the korean turbo.

Yeah, in the Ten no Koe and Populous you'll find a battery in there. In SFII' and the Arcade Card Pro you'll find nothing.

No battery in Populous. Apparently.

Really? It says, "ROMRAM HUCARD" on the spine like the Bank does, and Mednafen specifically states, "Support for Populous's backup RAM" as a feature.

I don't own this game, so I can't look into it. Maybe it uses some sort of micro capacitor or...flash? It does save without a booster/duo/etc, right?

Yes I know, it's really strange. Someone on this board opened their cartridge and there was nothing in it. I think I remember a lot of members stating it wasn't possible to save in the game as well.
