Dump a multirom cart?

[XRed_CubeX]

Hi, since I was little I had 2 GBA and I had a cartridge that contained many games, this cartridge just started showed a menu with 4 games and selecting the fourth, all 123 games appeared.
This cartridge is called "123 in 1"
Now with a ds phat and an r4 I tried to dump the cartridge, I can dump the wwe rom, i tried to emulate the rom with 2ds virtual console and i also tried with mGBA, the game selection menu appears but only the first game works and the rest of the 3 games do not work so I can not even get to the complete menu with all the games. I would like to ask you if it is possible to dump the entire cartridge including the part that is apparently missing, I also attach photos of the cartridge and the first menu.
I also add that if I press L and R, the VisualNes menu appears.

That is what we call in the industry as a 'multicart'. Try dumping them with an insideGadgets GBxCart RW device, that plugs into a PC, you can set the ROM size to anything larger to look for the rest of the data. Otherwise, if you've only got a DS OG/lite model use the GBA Backup Tool.

Some multicarts won't otherwise allow you to dump the rest of the ROM space, something to do with the mapper or copy protection.

I only have a DS phat, I dumped with godmode9i and it gave me a 32mb rom and it has the problem I described in the post, I tried to dump with Gba Backup tool but I only used the first version because the others froze, the rom came out of 16mb but it always has the same problem. I don't have that device you mentioned, I live in Italy, I don't know if there are Italian sites that sell it but I don't want to spend too much for this curiosity I have to dump

Ngul! I have to pay 62€ for dumping a GBA Flashcart. They are somewhat expensive devices.

ships from france and shipping + the device should be cheaper overall

Long shot but see if GBABF is able to read this cart: https://gbatemp.net/download/gbabf.37005/

You definitely need a dedicated ROM flasher/dumper like the GBxCart RW, Joey Jr, or GB Flash. All 3 of these are supported under the fantastic FlashGBX software by Lesserkuma. It can auto-identify the flash chip used, and then you can dump the entire ROM chip.
