rsn8887 has released a new version of the Amiga Emulator for the Nintendo Switch

Installation

Switch:
Download and unzip uae4all2_switch.zip
Copy the resulting folder uae4all2 to /switch/ onto your SDCard, ensure none of the "archive" flags is set.
You should now have the executable /switch/uae4all2/uae4all2.nro and a folder /switch/uae4all2/data/ with the keyboard icons and other data files on your SDCard.
Obtain and copy BIOS files kick13.rom (Amiga 500), and kick31.rom (Amiga 1200) to your SDCard into /switch/uae4all2/kickstarts/.
Optional: copy over additional BIOS files kick12.rom, kick20.rom, kickcustom.rom (for e.g. version 3.1.4 or any other user-supplied BIOS) to the same folder.
Use your favorite Homebrew Launcher or Homebrew Loader to start Uaeall2

MD5 of verified working kickstart rom files, you can test yours at onlinemd5:

kick12.rom (256 kB): (MD5) 85AD74194E87C08904327DE1A9443B7A
kick13.rom (256 kB): (MD5) 82A21C1890CAE844B3DF741F2762D48D
kick20.rom (512 kB): (MD5) FA4ACC75B49E880679FE02716AF24D71
kick31.rom (512 kB): (MD5) 646773759326FBAC3B2311FD8C8793EE

Other files might work, too.

You can purchase legal bios roms from Amiga Forever. They work. But since they are encrypted, you have to copy over your .key file along with the roms.
