@sorensenbrad - please see my sig for the main thread about PINN on this forum. It is a fork of NOOBS with enhanced functionality, including backup and restore, project spaces, password recovery, file system checking, OS customisation, recovery shell and much more. Yes it is also a boot manager and not just an OS installer.
Dougie suggested just installing new versions of Kali and Retropie as PINN supports both of those. This will be the easiest method for you, even if you have to reinstall your ROM games or whatever afterwards.
However, if you really want to copy your existing installations as they are, then there is a post on my wiki on how to do that. Please see:

PINN does not use SD card images because it needs to re-organise the SD card partitions to cater for multiple OSes. So it uses .tar.xz archives of each partition instead. The wiki article explains how to create them. Windows cannot easily deal with the ext format that is normally used for Linux partitions, so you will need to use Linux for some operations. But fortunately you already have a Linux computer - it's called a Raspberry pi!
