Switch to Carousel mode
Selecting this option will abandon the current Classic mode session and present you
with the games carousel from which you can select and play one of the built in games.
Reset machine
This option will end the current The Spectrum classic mode session and start a new
one using the ZX Spectrum model set in Default machine settings. In doing so it wipes
the ZX Spectrum memory and ends the current cassette tape saving sequence and
nishes writing to the current cassette tape le.
Using custom operating system ROMS
Each of the original ZX Spectrum models had its own version of the Sinclair ZX Spectrum
operating system permanently stored within it on a Read Only Memory (ROM) chip. The
Spectrum is similar and has its own compatible version of the operating system which
is sufcient for most uses, but does lack a few specialist features found in particular
on later models of the ZX Spectrum.
Should you require the use of these additional features and you own the original ZX
Spectrum ROM chips, you can put the appropriate ROM image les on a USB stick
for The Spectrum to use instead of its own operating system.
The ROM image les must be stored in the folder /THESPECTRUM/roms/ on your
USB stick. The following table gives the lenames The Spectrum expects the operating
system ROM image les to use for each of the ZX Spectrum models:
Machine model ROM lename Description
16K / 48K
48.rom
A single 16K ROM le.
128K Universal
128-0.rom
128-1.rom
The 128K and universal models use two 16K
ROMs for a total of 32K of ROM.
+2A
plus3-0.rom
plus3-1.rom
plus3-2.rom
plus3-3.rom
The +2A model uses four 16K ROMs for a total
of 64K of ROM.
