Yup, you can get Sonic 1, 2 and CD on the amazon store, IIRC you'll have to sideload kodi though, not a massively difficult task. It's as simple as turning on developer mode in the settings and then using an app on your phone to adb install the kodi APK to the fire stick. You can also just use adb in a terminal on your PC or whatever, up to you - but there's some apps on the play store that make it super easy.
