I write this text to see if you can help me with this problem:
I have a ROM expanded to 4MB, patched with the Custom PowerUps 3.3.3 patch, and the Speedbar, wall_kick and SMB3Koopers patch.
But, when I patch the Flagpole file from this pack https://www.smwcentral.net/?p=section&a=details&id=13882
the game crashes when I open it in an emulator!
I tested with a vanilla emulator and it works even without any Custom Sprite inserted.
Many of you could say to me "Then use the Flagpole sprite", but I don't want to use that sprite, since it occupies the SP4, and I want to use it for other custom sprites.
One possible solution that has occurred to me is to create a patch based on the Custom Sprite code so that the Goal Point Tape behaves like the Flag.
Somebody can help me, please?
