Resigining 'Eskiss'?

Hi, my favorite ps3 3.55 homebrew game was always Eskiss with move support by Kakaroto. However it won't install/play on 4.XX cfw (I'm currently on 4.30 ErmaC).

Can some kind soul please resign the pkg to install/play up to 4.30? Or at least tell me how I can do this? (Bare in mind though I am on a mac)

Thank you for any response,
