Any way to rip Neo Geo sprites without using Winkawaks?

[eureka]

Yo, Noticed that there wasn't any Samurai Showdown III sprites on the site and wanted to fix that.  I plan on doing it, but is there an easier way to do that than just using the tile viewer?  Data ripping is difficult because the sprite data is 2BPP (Most Neo Geo games are encoded like this), unless they're a program that turns them back to 4BPP?
