These are the 512 KB system ROM files (256 KB ROMs won't work on many mobile emulators) to run Amiga OS versions 1.2, 1.3, 2.04, 3.0 and 3.1 in emulated computers like the Amiga 500 and Amiga 1200.

Below is a list of answered questions regarding Kickstart ROMs (in no particular order), as answered by Jeff Weeks, Ville Jouppi and Mike Innes.

What are the exact dependencies that the Amiga 3000 Kickstart ROMs have on a MMU or other A3000-specific hardware? I know it uses 68030-specific MMU commands and I'm guessing it accesses the SCSI controller quite directly, but as before, I haven't disassembled it. Did more than one version of Amiga 3000 SuperKickstart 1.3 Bonus code exist?

What is the internal structure of a ReKick/ReCode ROM image? What encryption is used for ReKick images? How do these images differ from standard EPROM images?

Header = 108 bytes of text
'AMIGA ROM Operating System and Libraries: Copyright © 1985-1992 Commodore-Amiga, Inc. All Rights Reserved.'

Then 512KB of 'encrypted' ROM image, which is a simple XOR using $DEADFEED as the key

Finally, more text at the end:
'AMIGA ROM Operating System and Libraries: Copyright © 1985-1992 Commodore-Amiga, Inc. All Rights Reserved.'
'Beta Release! Do not distribute!'

They are different from a real ROM image (apart from the obvious change of base address from $f80000 to $200000)
Exec and Expansion had minor changes, the rest of the modules are identical.

IIRC, the ROM name was changed to 'Beta ROM', and expansion had some code to patch in the already existing expansion board list instead of trying to create it again, and also to remove the memory used by the ROM image from the memory list.

What is the meaning of the term 'Kickety-Split' (referred to by KickInfo)?

It's an 8 byte 'ROM header' found in the middle of some 512KB ROMs, essentially splitting the ROM into 2*256KB ROMs

As to why they added it, the only possiblese I can see for this is if some old game is trying to reset the Amiga and assumes it has a 256KB ROM and calls $FC0002 instead of $F80002.

What is the significance of the Ident field reported by KickInfo?

That's the first 2 bytes of the ROM, used as a chip identifier. Since the 68k bootstraps by setting its PC register to the address stored at address 4, the first 4 bytes are 'free', and normally have 2 bytes of ROM ID followed by JMP <coldstart address>.

Several IDs are used to specify what type of ROM it is:

All of the non-physical aspects of yourself — your thoughts, your beliefs, your memories, your emotions — are also made up of energy. The emotion code pdf. But there’s more.

$1111 = 256KB
$1114 = 512KB
$1116 = 'Rekick' 512KB

There might be other values such as a 256KB Rekick or 1MB or 2MB ROMs. Looking at the 68k, only the low nibble of each byte is used. This is the same loading scheme used by expansion ROMs such a the A2091.

What exactly does the following block of code do (presented in hex)?

That's the new privilege trap code installed by the decigel patch.
It checks for a MOVE SR,<ea> instruction and changes it to a MOVE CCR,<ea> instruction (and flushes instruction cache on 020+ too).

See attached disassembly, I also added the comments from the source on aminet (http://aminet.net/package/util/boot/Decigel)

Also note that Bryce Nesbitt's comments state that 'This code is not expected to function on the 68040.'
I've noticed this patch code is never immediately after the last module in ROM, which suggests to me it wasn't included as part of the build process, but added later.

Yes. This code will be either 8 or 16 digits. If your phone is asking you for a 'subsidy code' this is the same as an unlock code. Motorola c117 unlock code free online.

No idea if this was an 'official' mod by the developers though, it would be silly for a developer ROM to use code known to be a problem with an 040.
It would also be trivial to add this patch to exec if they really wanted to make it part of their build process.

Was Kickstart 1.0 ever made available in PAL form?

No.

What internal version were the A3000 softkick 1.4 boot ROMs?

Seems it is based on 36.16, but if you take a look, it has a second, newer copy of exec.library towards the end where it really boots from. This probably saves time, the superkick loading modules are right after it. I haven't done a disassembly though.

Were there any byte-level differences between the A3000 SuperKickstart 2.04 image and the physical ROM image?

No, the difference is that bonus code is added at the end.

Did an A3000 SuperKickstart 3.1 (40.068) ROM image exist? If so, were there any byte-level differences between it and the physical ROM image?

Educated guess: it probably did exist. All the 3.1 SuperKickstart disks I've seen floating around had the final version of the 2.04 bonus code tacked on the end.

What are the exact dependencies that the Amiga 3000 Kickstart ROMs have on a MMU or other A3000-specific hardware?

I know it uses 68030-specific MMU commands and I'm guessing it accesses the SCSI controller quite directly, but as before, I haven't disassembled it.

Did more than one version of Amiga 3000 SuperKickstart 1.3 Bonus code exist?

Yes, three versions:

28add9f722d4ab29a12d2d94244fafc5 (bonus.1.3-36.141 and bonus.1.3-36.143)
a6a808a0410c7d3ee5f083857a4c8c92 bonus.1.3-36.202
66a8d761932ef2c46a802c448002c2df bonus.1.3-37.175

Were any softkick tools available from Commodore other than KickIt?

Yes. Maprom, mmukick, ReKick (same name as a tool by Thomas Kessler). Also Dave Haynie's SetCPU can do ROM remapping via the MMU, but according to the documentation it was his personal project.

DISCUSSION

A: Amiga Forever Plus Edition (also included in the Premium Edition) includes ROM and system disks between version 0.7 and 3.X, including 1.0, 1.1, 1.2, 1.3, 2.04, 2.05, 2.1, 3.0 and 3.1.

To access the ROM files select Open Folder/Amiga Files from the File menu in Amiga Forever, then go inside 'Amiga Files/Shared/rom' (or see 'Amiga Files' at the root of the distribution medium).

Even the ancient 0.7 ROM image is included, as it is required to run some memorable software, such as the one that was demonstrated at the 1985 Launch of Amiga event in New York, with Andy Warh
