First of all this only works with dashlaunch 3.03 .
You do not need to unistall dashlaunch at all either.
Use xexmenu , go to your Dashlaunch folder, locate default.xex and start it.
When in dashlaunch menu press LB and you will be in the setting mode of dashlaunch.
Next go to Unload Dashlaunch, and unload it.
Then go up to the launch folder and bring up the .xex file you want to load (or use nxe dash to start the game) and the game will no longer freeze on the 0 second mark.
