indeed. as long as the HBC installer is on the root of the sd card and named boot.dol you will have no problem there. and for the banner bomb you only have to backup the private folder from your sd card and then delete it (if there was one on it) and then copy the private folder from bannerbomb over to the sd card. either way if it won't install and the installer simply freezes that means that the systems IOS's aren't trucha compatible versions and the trucha bug is required for the HBC installer to install.
