Thanks ace9094,Ill give that a go.
Also,I found out though with the Rogue FW it also has the option to change icon image,handy as well.
But ofcourse actually editing the opk file would be better cause you can use it on Stock FW too then.
But yeah,Ill follow your guide and see if I can do that myself to other emu's.
edit: Well it worked,sort of..the repacking went fine,the icons changed but the names in the RG350 were the same still even though when packing I selected a new name.
I think the top or bottom tab must be selected to edit the actual opk name when packing so it shows up in the RG350 changed?
But choosing either ones has other issues as asks for executable etc.
