it's normal, just hit YES, RCO Editor will do for you.
I think it might be a good idea decompressing your rco with
Resurssiklunssi rather than converting in RCO Editor.
Try converting a topmenu_plugin.rco that way and you will destroy all of the text data.
thanks bro's for the advice i already figured it out! i decompressed it by ressullunski, decompressing the rco using rco editor will do but it destroy the txt data.
all i need now is a good OSK AND A GOOD GAMEBOOT for my REDHACKS THEME
any advice bro's?
