Hey, i havnt been on here for a long time.
So first things first, trouble downloading from this website, try this link.
Second, trouble updating the 1.5ee? Follow the instructions given in the email you received when you got the link.
Third, emulation running slow after updating amiberry? remake your emulator configs, old configs aren't fully compatible with new version of the emulator.
Fourth, Permission error? Type permission into the cli.
