Ripping Questions

[Yawackhary]

Sorry for the double post here, but I have a question. I'm trying to rip the sprites from Groove on Fight(which is Power Instinct 3) on the arcade, but I'm having trouble actually getting the sprites. I can find the "Press Start" and the title sprites, but I cannot find the character sprites at all. Is there a program that makes ripping sprites from arcade games easier? Or am I just going to have to just keep wanting the sprites?

EDIT: No, MAME's GFX viewer doesn't work.

I did a bit of research and it is a STV game that uses the Saturn hardware (which might explain why MAME's tile viewer doesn't show the characters, in fact the same can be said for most games that uses the Sega arcade boards [at least from Hang-On to when they full switched to just 3D only arcade games]).

The only option probably would be try to see if you can find the sprites in GGD/TileGGD which you would have to unzip the ROM so a bunch of files appear. If you can't find them there, well apart from capturing and getting screenshots I can't see any other way round it unless you grab the Saturn version but that apparently has missing sprites in that version. Most games that use Sega's arcade boards seem to be a bit on the undocumented side and even with TileGGD it can be a hit (like Crack Down) or a miss (Dynamite Dux due to unsupported bbp mode).
