OK,
you are using the igames theme, so you need to edit your themes/igames/theme.php.
To remove the buttons you don't want, find the main_menu2 template, as here;
$template_main_menu2 = <<<EOT
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td class="top_menu_left_bttn">
<a href="{ALB_LIST_TGT}" title="{ALB_LIST_TITLE}">{ALB_LIST_LNK}</a>
</td>
<td><img name="menu_spacer" src="themes/igames/images/menu_spacer.gif" width="2" height="35" border="0" id="menu_spcer" alt="" /><br /></td>
<td class="top_menu_bttn">
<a href="javascript:;" onMouseOver="MM_showHideLayers('Menu1','','show')">@</a>
</td>
<td><img name="menu_spacer" src="themes/igames/images/menu_spacer.gif" width="2" height="35" border="0" id="menu_spcer" alt="" /><br /></td>
<td class="top_menu_bttn">
<a href="{LASTUP_TGT}">{LASTUP_LNK}</a>
</td>
<td><img name="menu_spacer" src="themes/igames/images/menu_spacer.gif" width="2" height="35" border="0" id="menu_spcer" alt="" /><br /></td>
<td class="top_menu_bttn">
<a href="{LASTCOM_TGT}" onMouseOver="MM_showHideLayers('Menu1','','hide')">{LASTCOM_LNK}</a>
</td>
<td><img name="menu_spacer" src="themes/igames/images/menu_spacer.gif" width="2" height="35" border="0" id="menu_spcer" alt="" /><br /></td>
<td class="top_menu_bttn">
<a href="{TOPN_TGT}" onMouseOver="MM_showHideLayers('Menu1','','hide')">{TOPN_LNK}</a>
</td>
<td><img name="menu_spacer" src="themes/igames/images/menu_spacer.gif" width="2" height="35" border="0" id="menu_spcer" alt="" /><br /></td>
<td class="top_menu_bttn">
<a href="{TOPRATED_TGT}" onMouseOver="MM_showHideLayers('Menu1','','hide')">{TOPRATED_LNK}</a>
</td>
<td><img name="menu_spacer" src="themes/igames/images/menu_spacer.gif" width="2" height="35" border="0" id="menu_spcer" alt="" /><br /></td>
<td class="top_menu_bttn">
<a href="{FAV_TGT}" onMouseOver="MM_showHideLayers('Menu1','','hide')">{FAV_LNK}</a>
</td>
<td><img name="menu_spacer" src="themes/igames/images/menu_spacer.gif" width="2" height="35" border="0" id="menu_spcer" alt="" /><br /></td>
<td class="top_menu_right_bttn">
<a href="{SEARCH_TGT}" onMouseOver="MM_showHideLayers('Menu1','','hide')">{SEARCH_LNK}</a>
</td>
</tr>
</table>
EOT;
And replace it with this;
$template_main_menu2 = <<<EOT
<table border="0" cellpadding="0" cellspacing="0">

<td class="top_menu_left_bttn">
<a href="{ALB_LIST_TGT}" title="{ALB_LIST_TITLE}">{ALB_LIST_LNK}</a>

<td class="top_menu_bttn">
