Quote from: zhulien on 06:16, 05 June 23Hi,In a CPC, are the external upper ROMs treated as ROM by the CPC, or is it only treated as ROM because it is ROM? i.e. if it were changed to RAM, would writes go to it or does the GA prevent writes going to the ROMs?
Quote from: andycadley on 13:01, 05 June 23The design of the CPC also relies on write-through being a thing. I.e. when ROM is paged in, it is expected (and required) that writes will still go to the underlying RAM that is present. Committing those writes to ROM instead of or as well as RAM would probably have unintended consequences.
