I am working on a game for RMXP that is based off of NES "retro" graphics. A lot of which I am putting together on my own, with a little bit of help from other already made resources. Well here is a cave tile-set i am working on. This is an early submission, so expect changes. Feel free to use this if you would like to, just credit me. That's all i ask. Have a nice day.
Oh, here are the auto tiles that go along with it.
