GENS has a VDP viewer where you can browse the data. This is how I've ripped the majority of sprites I did.
What you use are the keys on the right side of the keyboard.
* scrolls through palettes.
- and + scroll up and down the data.
On the letter keys, X toggles to show the in-game scene. It also triggers a way of changing from underwater palettes.
There's probably more keys. Best to find a documentation about the VDP viewer via Googling.
Works for Sega CD games as well. Not sure about 32X though.
