Did small test below:
+ Skin.ini with the line "Version: 1" or none and NOT changing current skin's name to "User"
_ No small background on each mode of every beatmap
_ No "pause_retry.png" and "ranking_retry.png" conflict at the result board
_ Stilll have "ranking_replay.png"
+Skin.ini with the line "Version: 2" or "Version: 2.2 " or "Version: latest" and changing current skin's name to "User"
_ Has small background on each mode of every beatmap
_ Showing "pause_retry.png" instead of "ranking_retry.png" at the result board
_ No "ranking_replay.png"
