 UAE also supports alternative system ROMs, such as those derived from the AROS project, however these do not provide the same degree of software compatibility as the original ROMs.UAE has been ported to many host operating systems, including Linux, macOS, FreeBSD, DOS, Microsoft Windows, RISC OS, BeOS, Palm OS, Android, the Xbox console, the PSP, PSVita and GP2X handhelds, iOS, the Wii and Dreamcast consoles, and even to AmigaOS, MorphOS and AROS.There have been many threads in the past on Usenet and other public forums where people argued about the possibility of writing an Amiga emulator.
