Mortal Kombat 1 & 2 (Game Boy): Is there a way I can split the game ROMs from the main ROM?

I bought and dumped my own copy of Mortal Kombat 1 & 2 for Game Boy. The two-in-one cartridge, not the individual games. Why? Because I wanted to do it that way. I have my reasons.

I'm well aware that the game doesn't work through emulation because the menu screen boots you back to the copyright screen after you pick a game, no matter what you do. Thus I'd like to know if there's a way I can split the game ROMs from the main ROM so that they're playable through emulation. It shouldn't be that hard right?

If I can't, then that's fine. I plan on also buying and dumping Mortal Kombat 1 and 2 for the Master System later on.

You might be able to do that with a hexadecimal editor like HxD. The exact contents from Mortal Kombat are located on address range 40000-7FFFF. Mortal Kombat II is located in the range 80000-BFFFF.

I'm not sure if GB roms have any kind of checksum, but these address ranges are almost exactly the save as the individual MK1 and MK2 roms.

Look, when OP told that Mk 1 & 2 Rom is not playable on emulators, I decided to test out on my Everdrive X7. It didn't work either, but as I was on clone hardware, I gave no importance.

Tonight I tested on an original Gameboy Color, and... it not work either!!! Now I'm curious why. Do this cart use a mapper that the everdrive do not support?

Anyway, today I also update my SD2Snes, and not it officially features Super Gameboy suport. On the SD2Snes Mortal Kombat 1 & 2 rom works just fine.
