++description = "A port of the UAE4ALL Amiga emulator, which is itself a continuation of the E-UAE emulator, to libretro. It emulates most Commodore Amiga 500 hardware with OSC 1MB Chip. The core has no built-in Kickstart, so you need to provide one. This core is in the development stage (experimental)."
