The program throws a NullReferenceException when attempting to change the channel title of several Japanese wads. Attempting to edit the channel title of the following wads on Windows will reproduce the issue:

• Mr. Heli no Daibouken
• Bomberman Panic Bomber

The stack trace is as follows:

System.NullReferenceException: Object reference not set to an instance of an object. at ShowMiiWads.ShowMiiWads_Main.cmChannelName_Click(Object sender, EventArgs e) at System.Windows.Forms.ToolStripItem.RaiseEvent(Object key, EventArgs e) at System.Windows.Forms.ToolStripMenuItem.OnClick(EventArgs e) at System.Windows.Forms.ToolStripItem.HandleClick(EventArgs e) at System.Windows.Forms.ToolStripItem.HandleMouseUp(MouseEventArgs e) at System.Windows.Forms.ToolStrip.OnMouseUp(MouseEventArgs mea) at System.Windows.Forms.ToolStripDropDown.OnMouseUp(MouseEventArgs mea) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ToolStrip.WndProc(Message& m) at System.Windows.Forms.ToolStripDropDown.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

This points to a bug in the ShowMiiWads_Main.cmChannelName_Click function:

I could read my bootmii nand dump, but couldn't pack any kind of wad. Every time I selected the destination folder, this appeared to me:

Cannot call Invoke or BeginInvoke on a control until a window handle is created.

With the previous version of the app, I could pack wads no problem, but my wad manager couldn't install them because of mismatching TMD hash (Wii Mod Lite, Error -1022).
