By the way, if you're worried about this overwriting variables that you use for other things, which it most probably will, you should back up all your variables and then restore them after this is done. You can do this by copying all the variables (which occupy 54 bytes starting at _E86EC) to another place in RAM before running this and then copying them back after it's done. Just don't copy them to the end of L₁ because I use the last 8 bytes of it for temporary sprite data. You can always move my temporary sprite data somewhere else if you want though, just replace the two references to _E89EC-8 (the last 8 bytes of L₁) with some other location.

EDIT: I just remembered that I was using a fairly complicated sprite-drawing loop to draw the center line because it used to be drawn as a white line on a black background, but it's now drawn black on white and just inverted later. I couldn't use the Line() routine before, but now I can. If this program is compiled as a part of one that already uses the Line() routine, the attached file will be more optimized.

Alright, for all thos pixel artist out there, I have a new request.
I'd like a flowing water animation which can be any number of frames you see fit as long as it's reasonable (not more than like 16).
I'd also like the overworld sprites for Roland and Aria modified so the bottom 8 pixels (if you imagine the sprite in an 8x16 rectangle)  are standing in the water.
Thanks in advance!

Bump?

8x8, monochrome. Kinda in the perspective of the water FF1-3 is what I was thinking.

Looks good!
As for the character sprites, I'm using Deep Thought's Aria sprites, and for Roland I'm using yunhua's up and down sprites and nemo's left and right. I slightly modifed yunhua's down sprite by making the eyes one pixel taller. So yeah, the page 1 sprites with some modification.

Finally got some time...    
anyway, i actually modified the last two rows, since it looked messed up other wise, but yeah.  

can you rephrase that?  I didn't really understand
