Homebrew Question Installing NSP without actually installing it?

[cucholix]

Hi, have a particular situation here that hasn’t been able to resolve.

I'm trying to install a homebrew NSP forwarder BUT without actually installing the NSP, so I'm extracting it to romfs/exefs from the NSP, then via layeredfs overriding the files of a legit eShop game (a demo for example), but so far haven't had any luck, the forwarder throws me "Close software" error each time, I wonder if I need apply some patch before extract the NSP?
