こんな感じ(標準/5列/6列)横画面は(多分)使わないのでそのまま
  
……6列は流石に厳しいか(^^;
HYBRID W-ZERO3の画面の大きさに慣れると、WILLCOM03には戻れませんね
 
1.横画面は変更しないので、\Windows\SH_GridScene_854x480.cpr を単純に
  \Windows\SH_GridScene5_854x480.cpr、\Windows\SH_GridScene6_854x480.cpr とコピー
2.5列用 \Windows\SH_GridScene5_480x854.cpr

<Form Width="480" Height="854">
  <StartMenu_GridScene ID="Scene">
  <GridView ID="Start Menu Items List" Top="0" Left="0" Width="480" Height="750" Columns="5" Scrollable="TRUE" HexagonGrid="TRUE" HorizontalWrapAround="TRUE">
     <Image ID="Selection" Left="0" Top="-30" Width="120" Height="130" Source=".\StartMenu_Selection.png" />
     <Layer ID="GridItem"  Width="120" Height="120" OnAction ="GridItemAction">
        <Layer ID="Normal">
                <Image ID="Image" Left="30"  Top="4" Width="60" Height="60" ScaleStyle="Fit" />

        </Layer>

 6列用 \Windows\SH_GridScene6_480x854.cpr

<Form Width="480" Height="854">
  <StartMenu_GridScene ID="Scene">
  <GridView ID="Start Menu Items List" Top="0" Left="0" Width="480" Height="750" Columns="6" Scrollable="TRUE" HexagonGrid="TRUE" HorizontalWrapAround="TRUE">

  のファイルを作成
3.レジストリの変更
  [HKEY_LOCAL_MACHINE\Security\Shell\StartMenu\CustomGridForm]の値を
  5列なら"SH_GridScene5"
  6列なら"SH_GridScene6"
  戻すなら"SH_GridScene" に変更
4.再起動
