Options Advanced options Switch to classic mode.
Alternatively you can choose to have The Spectrum enter Classic mode every time
you turn the power on by changing the Boot mode, a configuration screen entered
by selecting Options Advanced options Boot mode from the game carousel.
Changes made to the Boot mode configuration take effect the next time you power
on The Spectrum.
To change the boot mode while in Classic mode, access the Boot mode item from
