    I found another Breath of Fire 2 NTSC/US Prototype cart. This one is different from the Carts on hidden palace. It has Capcom Stickers. It holds the US Version of the game CRC32: 72B5F02B . I used Sannis tool to dump the cart and it gives me a 4MB file that i compare with the final and the other proto. The dump work but im not sure about the 4MB, because retail and the other proto is about 3MB.

    Here a picture of the cart:

    What does the data look like at the end of the dump? I forget the text file settings for the retrode, but you may be able to set a size manually.

    Cart can take 4MB, that's likely why it's dumping as 4mb.

    See if last 1mb is blank or is repeating first 1mb

    Thanks for the tip Andrew! I checked the retrode site for instruction. But even if i force the retrode to do 24Mbit he gives me 32Mbit Rom. I tryed also the dump correction mode on and off. Hi/Low Rom... Than i was thinking to update the firmware of my retrode.
    But after the install of Flip Win10 dont get the DFU mode of the retrode. Always usb connection dont work any more ..

    Thats how the two roms end. Left the Protooverdumped 4MB and right the us retail version. Can i just cut it there?

    yes, FF is blank/nothing.

    Just cut the end off, make sure its exactly same amount of bytes as the retail.

    What does the internal header say about the ROM size?

    It can't be anymore than 3MB. The chips on the cart total 3MB.

    I was wondering if an improperly set ROM size in the header was throwing off the cartridge reader. Not that it really matters, I guess, since it overdumping instead of not dumping everything.

    The SNES header is located elsewhere. You can run the ROM through NSRT and it will give you a clear readout of the information in the header.

    The ROM size byte in the header is stored as the number of times you have to left shift 0x400 to get the ROM size. As a result, it can only represent powers of 2. It's presumably set to 0x0c, which would make the size 4MB and would account for the overdump.
