Flashback for Genesis not detected about cartreader HOT 9 CLOSED

Can you replace MD.ino with this version, upload and then test again?
It forces the OSCR to overdump the cartridge, curious what happens.

MD.zip

Ok, could you do one more test and temporarily edit the size of Flashback to 4MB in MD.ino by replacing 0x200000 with 0x400000 in line 777:

Dumping will now ofc produce an error. But I would be interested in how the ROM looks like in an hex editor like Nexus HxD at Offset(h) 00200000

Thanks for these additions in code sanni :) That's what I wanted to investigate since a while (since we confirmed "Shining Force" correct size). We used the same approach, making an big overdump to check where the final padding stops, and where repeated data starts.

I don't see this fix as an overdump, but more a "full chip dump". Until now we followed the info given in header, which sometimes just gives the rom/game size, but not the chip size.

also reduced the code a bit, and merged previous fixes with yours :

Hi.
can you confirm that the rom you obtained got a size of 1572864 ?

from cartreader.

According to the dat-o-matic no-intro overdumps it on purpose even though the internal ROM header declares it as a 1.5MB ROM.

If you trim the 2MB no-intro ROM to the correct 1.5MB you also get the CRC32 of 23A9616D.

Does this mean it can't be detected properly by the reader, or can the info in the files be adjusted to make it detect/dump correctly? The ROM plays perfectly fine and that is the CRC32 I get, but I haven't compared ito an official no-intro, I'm just checking out my own. Or will the reader only use no-intro CRC32s even if they aren't quite right? Learning how all this ties together.

That caused it to identify correctly, with a CRC32 of 9FEFB1AB

Just checking, did you still need me to check those sanni, or does this being closed mean you have the info you need?

from cartreader.

Got all the info I needed, thanks.
