So, I finally got NSMBe to actually run on my mac, and that's great.
There's a little thing though which isn't so little.

Say, I open a level. At first, everything looks normal and stuff, y'know:

Then, when I, for example, scroll with the horizontal scroll bar (I think it also fucks up with the vertical scroll bar) all the way to the end of the level and then back, I get this amazing, beautiful level start.

Basically, the graphics at the end overlap the ones at the beginning.
The thing is, though, the objects aren't really modified: it's only a graphical glitch and when you try to highlight the objects it only highlights the true ones.

Anyone might know why Wine hates me so much? (I doubt it's an editor problem)

Oh, also, I want to mention that I could not open a ROM at all when trying to use it with Mono. I do not recall the error but I can try again if no one has any idea about this.
I have a really cool hack idea but I can't ;-;
