No, there is no option for that. There is no way to get Folding@Home working again afaik. You could add a dummy icon anywhere you want easily enough but it would require you to edit some xmls yourself. If you are comfortable with that kind of thing here is a quick basic guide for adding a new dummy icon to the XMB:
1. First use FTP or a file manager to find the xml for the category you want to add something to. In this case it would be dev_blind/vsh/resource/explore/xmb/category_network.xml.
2. Copy the XML file to your PC, Then make an extra copy of this file in case you make a mistake and need to start again, or in case you want to revert your changes later. If you mess up this file the worst thing that can happen is you will have a blank network category. Simply replacing the xml with the original and rebooting will fix it.
3. Then you need to use a text editor like Notepad++ to add a new query like this at the top of the xml in with the other queries. This query is added so the OS knows to check if something exists lower down in the xml. The tags "key" and "src" can be anything you want, but it must be in this format:
Code:
<Query
class="type:x-xmb/folder-pixmap"
key="dummy_item1"
src="#dummy_item1"
/>
Note 1: On its own this above query will do nothing, you will see no changes on the XMB and it will cause no issues if you do not add anything else.
Note 2: The order of the queries in the XML is the order they will display on the XMB so add it where you would like your new dummy item to show up.
4. So with the above query added the OS will now check for a "View ID" item called "dummy_item1" lower down in the xml. You can put this next bit at the very bottom of the xml if you want, just make sure its before the very last </XMBML> tag. The order of the "View IDs" are not really important. So anywhere at all will do.
This example will add an item that will do nothing when clicked:
Code:
<View id="dummy_item1">
<Attributes>
<Table key="dummy1">
<Pair key="icon"><String>/dev_flash/vsh/resource/explore/icon/fah-xmb.png</String></Pair>
<Pair key="title"><String>Folding@Home</String></Pair>
</Table>
</Attributes>
<Items>
<Item class="type:x-xmb/module-action" key="dummy1" attr="dummy1" />
</Items>
</View>
This example will add an item that will act like an empty sub folder when clicked:
Code:
<View id="dummy_item1">
<Attributes>
<Table key="dummy1">
<Pair key="icon"><String>/dev_flash/vsh/resource/explore/icon/fah-xmb.png</String></Pair>
<Pair key="title"><String>Folding@Home</String></Pair>
</Table>
</Attributes>
<Items>
<Query class="type:x-xmb/folder-pixmap" key="dummy1" attr="dummy1" src="#dummy_sub_folder1"/>
</Items>
</View>
That's it really. This guide is for normal CEX FW or HEN, If you are DEX FW it gets a bit more complicated as you need to edit different xmls.
