Below is the concluding excerpt of the complete available HERE on Github by OSM-Made, to quote:


Now after two days I had managed to complete my goal of invoking both static and instanced mono methods. I was now able to call mono methods that were required to be called on the main thread. I now have set my sights on my next goals.
  • Refactoring my mono classes as they have a few issues at the moment mainly passing in pointers as variables.
  • Invoking constructor methods to create my own instances of classes.
  • Appending my own Widget to the TopMenu to begin work of drawing my own menu.
  • Making modifications to the current PlayStation user interface ie. Adding my own menus.
For now I am happy with my progress and I am very happy to share my journey with you all. I hope this has been an interesting read as well as informative. Hopefully it can serve as inspiration to others to learn more as well to contribute to the community.

Settings menu testing

Just a little test of the hook I wrote to make a new memory stream for the xml files that layout the PS4 settings menu.

Settings menu functionality

I finally got around to getting the settings menu to actually function :) Just need to set up an easy way to make this functionality easy to code for. I even got some of the debug menu stuff moved over soon no more need really for debug settings :D

This is great, this can lead to Debug settings on home screen and package installer instead of going to settings etc. Nice work.
