Changes

On CPC 6128 and DDI-1, the internal ROM 7 can't be cleanly disabled (it works on some machines, but it means the internal ROM and the flash chip both use the memory bus at the same time, and it happens that the flash chip is stronger in this fight. But it could eventually damage the hardware).[https://pulkomandy.github.io/shinra.github.io/gordon.html Source]

On Plus and machines without disk drives, you the internal ROM 7 can enable itsafely be disabled.

ROM 0 can always be overloaded, but remember that you will not boot to the BASIC in that case ([[Hackit|the Hacker ROM]] is a popular replacement ROM 0, for example). [https://pulkomandy.github.io/shinra.github.io/gordon.html Source]
