===XMB In-game icons removal===
*[[Rcomage]] usage notes:
The process is the same with the file '''[[xmb_ingame]].rco''' but this .rco contains the icon images, so for every icon removed at code is good to remove the icon image, is not needed to remove the images but this will make the final size of the .rco smaller
**dump resources raw, without conversion (unmark all the checkboxes)
 
**compile using zlib header compression (mark the zlib checkbox)
*Under '''ImageTree''' there are several '''Image''' elements that works as the 10 icons in main XMB
**Delete the '''Image''' line/s that defines the icon/s you want to remove
