Hi, I'm looking for the firmware for a the C8434 ARC Air powerbase. It's 'new' but i'm guessing old stock. It's currently on version 2.1 and will not work with the new ARC app and only the legacy app. Now it turns out that the firmware should be at https://www.scalextric.com/arc-firmware-update but the page is dead and just sends you to the Scalextric homepage. Does anyone have the firmware to hand? I've requested it from Scalextric/Hornby but I have not received a response. Many thanks
