Okay, so I ed the App fine, but on launch, it immediately closes.
I have X11 installed. When checking Console.app, it says this:
"[0x0-0x3f03f].org.raeiphon.osu!wine[457] /s/kristi/Desktop/Nick's Stuff/osu!.app/Contents/Resources/script: line 6: /s/kristi/Desktop/Nick's: No such file or directory"
I'm on a 2.13 GHz MacBook Intel Core 2 Duo running Snow Leopard.
EDIT: Fixed the problem. It's seems the problem was "Nick's Stuff" and it viewed the space as the end of the line.
However, while running on a 1.83 GHz MacBook Intel Core 2 Duo, the screen would show up as white, but you could hear the music playing. I got the following error message in Console.app
"[0x0-0x1d71d7].org.raeiphon.osu!wine fixme:d3d:context_apply_blit_state Applying blit state for an offscreen target with ORM_FBO. This should be avoided."
This error was being sent at least 10 times a second. And repeated until the program and X11 was closed.
