Hello, the problem is that some pages are erased from B3000-B6FFF, CAP is completely busted, and the end of RAP too. CAP is not an issue, but RAP is, that block contains some data but i'm not sure if that's something critical, i should check...

I have attached the repaired RAP. It was recovered from Extra Space.

I can try to build a new ROM with parts from your donor, unless anyone has a better idea.

All I did was repair the RAP using the partial copy in the Extra Space, and then replace the CAP, UDSBFW and CELOG with the donor's. The latter two segments were clear in the donor ROM, but the patient's segments contained data. You could dump the ROM again and reexamine the UDSBFW and CELOG segments.

In the corrupt ROM, the UDSBFW segment has been shifted downward by 0x800 bytes, and its last 0x800 bytes have overwritten the CELOG segment. I have extracted and attached the correct (?) version of this segment.

There are a couple of areas containing 0xBEEF. I don't know what this means.

Code:

Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00001F30  EF BE EF BE EF BE EF BE EF BE EF BE EF BE EF BE
00001F40  10 00 EF BE EF BE EF BE EF BE EF BE EF BE EF BE
00001F50  EF BE 00 08 FC 00 EF BE EF BE EF BE EF BE EF BE
00001F60  EF BE EF BE EF BE EF BE EF BE EF BE EF BE EF BE

It would be interesting to see whether the latest ROM dump has the same corruption.
