I ripped this BG and did the animations.
While the waterfall animation BG needed no treatment, the lava animation BG needed lots of work to animate properly.
Now it's all done via an ExGFX file. Check the sample level.
It's also comaptible with the Yoshi's Island - Cave Tileset.
Have fun using it!
Please remember to submit updates like this as a proper update to the old submission instead as its own separate submission. It's easier to keep track of them that way. You keep forgetting putting the full game title too, I fixed it.
Other than that, wonderful rip! old submission didn't include a palmask file neither the lava animation. Certainly a VERY welcome update, thank you so much
