The \"Kickstart ROMs\" box provides tips on how to buy a suitable package from the Cloanto store and where to find the correct ROMs therein. Of most importance is that you have Kickstart v3.1 for the Amiga 1200 (kick31a1200.rom) in the KICK partition on the microSD card. If you use an encrypted version of this ROM (from the Cloanto packages), the rom.key file must be in the same location.
Amiga Forever Essentials for Android  is far cheaper ($1.99); but it is only useful if you own an Android smartphone. There is no iOS version. Transferring the file involves a bit of work. The app shows the directory with the ROMs (/storage/emulated/0/Android/data/com.cloanto.amigaforever.essentials/files). The filenames of the two required files are identical.
The menu support allows selecting which amiga model to emulate. When switching model, UAE wii will try to load a matching kickstart image and thereafter reset the computer. If the kickstart is not found, it will keep the current, but remember that this might not give you a functioning Amiga. The model/kickstart mapping is as follows: 153554b96e
