I encountered some problems with the 2.10 version. These are as follows :
1. The music seems cluttered, it seemed the midis didn't sound that smooth as compared to the 183 & 184 players.
2. Turning off VSync makes everything return back to normal, but the transitition between screens doesn't seem that smooth. Turning on VSync & everything is at supersonic speed.
When VSync is turned on for the 183/184, screens transition is very smooth.
3. The 210 player doesn't seem to remember the location of the custom quest when I reload the player. I played quests from another directory & it doesn't seem to remember.
Haven't tried the editor yet but it looks awesome.
