Thanks to the archive that SkymanDr uploaded days ago, Phantasy Star Cave now has most of Nak's old fan art that disappeared from his site a couple years ago. Be sure to check it out!
An updated patch for Shilka's Adventure has been released by M.I.J.E.T.! I would tell you what it changes, but the site doesn't tell you. In any case, Phantasy Star Cave has the updated patched ROM now.
