That's some pirate group if they can modify a ROM... Seriously, how come that program has been up there for months? You'd have thought someone has had it removed, citing DMCA law and what not.

I'm sure that any determined cracker can break the copy protection mechanisms present inside any given computer---think of all those nice modchips available for game consoles. The question is, as always: is the way to crack the system difficult and expensive enough as to scare off sufficient amounts of would-be-pirates?

Some people say that cats are sneaky, evil and cruel. True, and they have many other fine qualities as well.

Remember that ROM means READ Only Memory. Just look at the kickstart. You can save that off to disk and even modify it or softkick it. Same deal applies here.. They could modify OS4 to load the rom image from disk and access it from ram.

True, but the original thread implied that the ROM itself was modified. I'd certainly be impressed by that feat of hackery :-D.

Apart from that, I seriously wonder about the feasibility of softkicking these modern machines. We're talking the boot ROM here. That is not the same as the Kickstart ROM. Besides which, the old Amigas allowed softkicking thanks to continuous RAM refresh and resident memory areas, the Cold-, Cool- and WarmCapture-offsets deep in ExecBase, and a very interesting library call called SetFunction(). I have strong suspicions all this functionality has been removed. I would have, if I were to develop AmigaOS 4.

No, methinks the best way would be to extract the code in the boot ROM, modify it, burn it back onto an EEPROM, and bypass the protections that way. (Provided the EEPROM is electrically compatible too!) Far too much hassle for the casual user, in any case. (There was a thread about someone ripping the ROM's socket from the motherboard not too long ago.) Then I also suspect that it will not be easy to boot your illegally acquired machine-readable, deprotected version of AmigaOS 4, as it assumes either a forgiving boot ROM, or that you are already running some OS. And that brings up the softkicking problems again. Double if the machine has set up MMU tables.

Doable, yes. Easy, no.

As far as the DMCA goes.. That's US law. Aminet isn't limited to US servers you know.

Your point...? :-D
