Ahh... ok. Thanks for deleting it. I'm too busy in college so I don't get with hacks. Well, about the correction for the Sand Background, I just researched it and here it is:
VV = 249FE4
WW = 24A37C
XX = 24A618
YY = 24A844
ZZ = 249F98
The image (VV) is 249FE4. And I also noticed the tilemap (WW) ends with 3 (having the offset 24A373). The tilemap is 24A37C. I've checked the entire pointers for the Sand background so I get to observe it. That's it. The rest are good. :)
