[[Media:ROMUP464.BIN | ROMUP464.BIN]] '''Basic 1.1 for CPC464''' Auto Installer.
Install Basic 1.1 and corresponding lower rom (English version!).
And for best compatiblity it will set M4 rom to 7.
Just copy the attached file ROMUP464.BIN to your microSD card and from Basic type:
RUN"ROMUP464.BIN
It will ask you to press M4 reset (or power cycle) when it's installed.
If anything goes wrong, put the microSD card into a PC and delete from folder M4 the files ROMCONFIG.BIN and ROMSLOTS.BIN to set it back to default settings.
If everything goes as planned your CPC464 will now display Basic 1.1.
