Mostly copied from my help thread
The status bar is infested with zeroes! It works fine on an expanded vanilla SMW ROM, even with all the other patches applied, but it doesn't work on the ROM that I've been using to make ExGFX, that only has custom ExGFX and some levels. I've been unable to recreate it manually with the insertion of ExGFX, even the same ones that were in another ROM that has the issue.
I'm able to consistently recreate the issue.
-Take a vanilla ROM in Lunar Magic
-Open this level in ROM, save it to the ROM (level removed)
-Apply status bar patch
-In an emulator, enter any level at all, even ones that are not the one you just inserted
(the level is supposed to have ExGFX and map16 tiles associated with it but you don't even need those, the ROM doesn't even need an ExGFX list)
(not sure if it needs to be level 105; it definetly doesn't break if you extract and then reinsert the original level 105)
