I had made a discovery involving the osu!mania .ini files. This discovery involves the numbers of ColumnWidth (CW) and ColumnStart (CS).
These numbers deals with how many pixels on a 640x480 screen. When you're playing a osu!mania map on a W x H screen,
The left side of the play area starts at CS*H/480 and the right side ends at (CS+Sum of CWs)*H/480).
I made that discovery after realizing when I play on a 4:3 window with the settings CS =440 and (sum of CWs) = 200, the right side of the play area was just at the right side of the window.
The maximum width for the left stage sprite is 738 pixels, which covers the left side of the play area when you set ColumnWidth to 460.
