Well I also tried to make your pkg by deleting the native folder because I had not done that before. It didn't seem to have any effect on the game, so I wondered maybe I need to install the package through Target Prodg and everytime I try it says it needs 3.7 SDK or later so i downloaded the SDL installed it, but it doesn't seem to recognize that.
I do not currently have USB drive that can hold the game, so I thought Game mounter ment I I could do it right through a network cable.
I have no idea what Debug settings are in my favor I know when I change something to Release and not Development and it asks me to restart the PS3 then Target ProDG won't connect to it.
The Game does show up in the app/home folder it just gives me that insert disc error.
