Action Replay ROMS (100%)

[andreas]

Well, someone might ask now: "What does he want now again?!"

But while talking with Toni about a related issue, I got the info that the first 8 bytes of the AR roms contain random data if ripped with a software ripper.

What we could need (CAPS guys listen, too! ) is a 100% AR dump ripped with a hardware ripper.

Does this already exist and/or is this possible to do?

I think as CAPS are now able to preserve ANY game 100%, so this might be a suggestion (not a real request!) to consider this in the future.
Maybe with original manual and all.

have always been $4e74,$4e74 then the String "ACTION REPLAY AMIGA MK III".... etc, etc.

If its was eight random bytes, then the string "ACTION" would be screwed up! I think someones telling you fairy stories!

Byte 0 is used by ROM code to detect the AR activation type, Amiga reset, freeze button or breakpoint, also writing to bytes 6 and 7 is used to switch chip RAM back to 0x0.

You are right, bytes 4-7 clearly come from ROM when reading.. I don't know why I forgot that.. Strange logic...

-> at least byte 0 can't be data from ROM. (at least not always..) Thats why I'd like to see real rom dump to confirm it.

I have two AR2-ROMs, both starts with $2018,$2018. And I have two AR3-ROMs, one starts also with $2018,$2018 and one with $4E75,$4E75. Doesn't look like random data to me...

Ok, lets change "random" to "something that is not from ROM"

I now have proof that first 4 bytes are not read from ROM:

First 4 bytes contain 4e74 4e74 when using freeze button and typing "M 400000" and 4e75 4e75 when AR was activated by break point.

and I was wrong again, status register is byte 1, not byte 0 (0 is used to hide AR ROM when exiting)
