These settings control which ROM image(s) WinUAE will use. At least a Kickstart ROM is required to emulate a classic Amiga.

WinUAE - ROM

System ROM Settings

Main ROM File specifies which Kickstart ROM file to use. ROMs in the specified path will be automatically detected.
Extended ROM File will provide CDTV or CD32 support (supplied with Amiga Forever).

MapROM Emulation will provide support for BlitzKick type tools.
ShapeShifter support will enable the ShapeShifter 'PrepareEmul' support, so you don't have to KickShift your ROM-images. This also allows Amiga Forever users (encrypted ROM-images can't be KickShift'ed) to use ShapeShifter.

Miscellaneous

Flash RAM or A2286/A2386SX BIOS CMOS RAM File will allow you to save to NVRAM (Non-Volatile RAM) like the CD32
Real Time Clock file allow you to specify a RTC file.
