There is no longer support for ini files.
Your MXM_Entry.xml file should look like:
<Config>
<Item>
<Title>Rocky</Title>
<Description> </Description>
</Item>
</Config>
Also, don't set these:
<TitleDelay>0</TitleDelay>
<SaverDelay>0</SaverDelay>
to zero... try 5 and something large for SaverDelay (I'll have to check this, 0 may be OK)
Lastly, the MXM_Entry.xml file of course, belongs in the game directory.
