This was first ripped by Yawackhary. I converted this for SMW usage. The downside is that you won't be able to use bushes and slanted pipes. The Ice Planet was also first ripped by Belial. I did the same thing there. About the Ancient Planet tileset: you can use this for battling in an ancient dinosaur land. This does feature the following:
-the BG and FG are included and the design is just like how it's supposed to. If you do remove the dinosaur for the BG, then it can fit into a nice forest BG.
-the BG uses 78 tiles, but the FG is the real kicker, as that uses 312 tiles, but fortunately, there's the sample level with the BG and FG fully inserted.
-oddly enough, the BG and FG use the same palette.
Give credit to Yawackhary. Also, give credit to Belial if you use the Ice Planet set.
Also, not sure what tag goes here, besides ancient.
