NSW-Custom-Game-Icons VS IconGrabber

just follow this guide -> https://sodasoba1.github.io/NSW-Custom-Game-Icons/

but you can also use NX-GIC icons to mass transfer icons as a temporary measure https://github.com/sodasoba1/NSW-Custom-Game-Icons/wiki

It's not worth it. I tried and actually succeeded with this Guide and its not all that

You need a Custom theme,Systweak for you current version of AMS, The easy way is to set up: Icon Grabber on switch(Needs set up from a computer) or NSW Custom Game icons(Computer and switch) or you need to manually set up each title.(I never got manual edits to work) Good luck and go slow it is a lot of work to get started. Using NSW custom icon grabber was the easy way to insert my own covers on my own forwarded homebrew apps.

A word of warning this theme is by no means is coming with the custom icons for your titles(games). To make this theme work you need systweak installed. As well as needing to set up each title individually with custom icons with either manual patches or using icon grabber And or Nintendo Switch custom game icons

I've written up a Tutorial

Been some time since I last used a Vertical theme so this may be misinformation, but I think you can use Icon Grabber to speed up the process/make it near automatic

here it is.

the icon ratio is 2:3 and fully supports https://github.com/Slluxx/IconGrabber (made by sluxx)
