So after repointed standing map sprite table at 0xb2a610(free space), I inserted a custom map sprite at B2AE10(0x6B). And this happens...
It only displays a shadow.
I'm sure that map sprite itself works perfectly fine in other games. So I guess it must have something to do with hex. I already changed all these address 26706 2678A 2680C 26C68 27250 27B96 27C82 27D30 27DF0 27E84 27F5A 2804C to FF. But it didn't seem to work.
Please help :(
Edit: Never mind I figured it out lol
Edit:Solution
After use Standing map sprite editor in nightmare, open your rom in HxD, go to the address of your repointed table, to the address of that map sprite, you'll find it displays like 02 FF(unknown number) 01 FF(size 16x32) B4 C9 B2 08(graphic address). Change FF to 00 to solve the problem. (Don't know if csv have the same issue though)
