To open an Interface II ROM cartridge
On the File menu, click Open.
Locate the cartridge file, click it, and then click Open.
Tip
You can also use the shortcut key, Ctrl+O, to open Interface II ROM cartridges.
If you hold the shift key down when opening a cartridge file, Spectaculator will not switch to Spectrum 48k mode. This can be useful if you need to load something like the ZX81 emulation cartridge, which requires Spectrum 128 mode.
