Missing tiles

[Mariofan5000]

For some reason, when I'm playing, certain things like quicksand, waterfall tops and SMB3 Doors don't appear, even though their image files are in my graphics folder. I tried redownloading, they appeared, when I copied these redownloaded back-ups to my main folder, nothing changed.

It appears that the BGOs may be PNG file. GIF is compatible with SMBX, not PNG.

All of them are gifs. These missing tiles are still in my folder, untouched, yet they don't appear in my normal folder for the game after I changed most of the sounds and music to higher quality ones.

Re-installing SMBX usually fixes this issue.

As I said earlier, I already re-installed it, yet when I replaced the base folder's files (except the other folders), I it didn't help the original file's "Spirit Ball attack".
