Custom Homebrew Icons on more recent firmware??

Hi, I've been following the guide on making your own custom icons for homebrew apps here: http://www.dcemu.co.uk/vbulletin/showthread.php?t=11376

I wondered if everything in it still applies - specifically if an app doesn't have a Kxploit-ready folder?

Example:

/s9xTYL/
/s9xTYL%/ <- The EBOOT.PBP inside this folder is the one to be used/edited.

For newer homebrew apps/emulators, there is no second folder, only the main one and I wanted to know how to edit these PBPs, if it was the same, or there are newer/different ways of editing the icons in these.

Thanks. :)

I think it still applies, haven't tried it though, just use the eboot in the single folder
