Hi boardjunkie,
Some stuff will work by just copying it, most programs won't as they need to be installed. Regarding modelines, these can be saved/restored using Winmodelines.
The sound issue you mention is not such. You can't run most vertical games v-synced and still run at 100% speed, it's the whole game running slower not only the sound. Enable triplebuffer & multithreading for those games and v-sync will be disabled.
