I think it is overdumped. After trimming it to 64 Mbit it works and matches 2278 - Dogz (U) except for serial and complement (just 2 bytes total).

2668 - Dogz (E), 128 Mbit -> 64 Mbit, 61F88CA6 -> AA8DEA30

Please, could anybody confirm it?

If you inspect the data at 0x800000 and onward it's characteristic of reading beyond the cart size limit. Coupled with there being 0xFF's leading up to this it's my cursory glance that you're right.

If I still have the cart, I'll check it again.

Trashman's is at 64Mbit (#2278) so I probably screwed up. ;)

If they're all at 64Mbit, then 2577 is also overdumped.

However I don't think 2577 - Dogz (E) (M4) is overdumped. The data past the 64 Mbits mark (0x7FFFFF) doesn't looks like overdumping stuff, maybe it is language related.

I've performed a size comparison between dupes in each "family" of games. The result is the following list, where there are differences in 39 families. I found the 2668 possible overdump by looking at this list. It seems to me to be the only possible overdump, but I post the list here anyway just in case someone wants to give it a look.

I checked out 2668 (B82P) this morning and indeed it should be 64Mbit.

The header information of file Dogz (E)
-----------------------------------------
Software Title: DOGZ
Game Serial: AGB-B82P-EUR
Maker Code: 41
Publisher: Ubi Soft
Version: 1.0
Logo Code: OK
Complement: BCh
Save Type: EEPROM_V124
File Size: 64 mbit (8388608 bytes)
CRC32: AA8DEA30
-----------------------------------------

Kazumi, if all you did was ROM Trim from 128Mbit to 64Mbit, then there is no need for a patch.

===============================================

Yes, I simply trimmed it, so no patch needed, of course. The file above is just a list, a .TXT file.

I am interested to know how you confirmed the size of the game?

As a followup to this report, someone could scan their entire gba collection for the following sequence, and if found at a position in the file that corresponds to a power of two it is likely an overdump. I'm too lazy tho.

Code: Select all

 
 00 00 00 00 02 00 02 00 04 00 04 00 06 00 06 00
 08 00 08 00 0A 00 0A 00 0C 00 0C 00 0E 00 0E 00
 
If they're all at 64Mbit, then 2577 is also overdumped.

This is clearly not the case at all. There's an obvious end to cart data at 0x92b060 and nowhere does it display the previously mentioned characteristic.

Furthermore, doing a quick debug run reveals the following:
.text:080EDC70 LDR R5, =off_885D1D8
(snip 2 instructions)
.text:080EDC76 LDR R1, [R5]
Meaning the game is loading data from 0x885D1D8 into cpu register r1. 0x885D1D8 being in the 64mbit you suggest is overdump data.

At 32Mbit, the game has graphical anomalies, so the game is indeed 64Mbit.

Please use my previously listed information for the corrected DAT and for the Wiki.
