I'm going to share some of my hacking notes for Bart's Nightmare on SNES.
In the Temple of Maggie, the top part of the screen (with the Maggie statues) will scroll at a different pace than the bottom of the screen where all the stepping stones are. This makes it impossible to align the Maggie statues with the stepping stones that would normally have a pacifier fly across them. In fact, the stepping stone walkway is a lot longer than the Maggie statue background at the top of the screen.
PAR code 7E0915?? was used to get the rest of what I needed from the top half of the screen. It only works when Bart is in the air, but paired with the code to make falling non-fatal this is not a problem. If the value is 01 the screen will scroll to the left. Set the value to 20 or higher to make the screen scroll to the right. The lava pool extends forever in both directions.
PAR code 7E00B200 makes falling non-fatal. If you jump on a flaming block and go into the lava you can just jump right back out. You can even out run the pacifiers by mashing right on the d-pad.
PAR codes 7E0E389E and 7E0E39E1 freeze the background animation.
The stepping stones in my maps represent the original position of these stones. This is the way the path will look before you take even one step. To do this, I went into BizHawk's hex editor and froze everything from 0E3B-0ECB in the WRAM.
36 stepping stones in a row multiplied by 4 rows = 144 total stepping stones in the Temple of Maggie.
