Hi,bro.Thanks for you method to fix custome nsp to pack and play normal in fw 19.I'm not sure, sometimes when you remake them with the same icon files they work fine in FW19 so I think that maybe that there's an issue with the way that jpg files are being packed. I'm thinking about making a new nro forwarder gui with visual studio which can do better image conversion using this library:

I've had a look at the script that this program uses and installed AutoIT to compile the scripts into an exe, but I can't see anything wrong. TBH The program needs a refresh though and I have my own ideas on what I want to do.
Also I think that hbl.nsp/nsp-forwarder needs updated, wait unil the new Atmosphere is released.

(I've added the new debug flag to this).
I have to replace control nca icon less than 100 kb.
After I did this,hacbrew pack nsp can run normally after packaging and installation.
I will come to fix other fw19 error custome mod nsp game.
Thanks for you method.Your are the best!
