If you run .nds files of dsiware directly from twilight menu, the compatibility is not as good as you first install them to dsi and make .launcharg files and them launch dsiware from twilight menu.I thought twilight menu could launch dsiware. Why would you want to install them in the first place?
For example, if you run .nds file of 'WarioWare - Touched' directly from twilight menu, there will be no sound. But if you install the .nds file and them run it from twilight menu, it runs perfectly.
